WARNING
Do not use decontamination spray on personnel. It could cause personal injury.
Do not take any of the chemicals in this kit internally. Personal injury can result.
Avoid direct contact with all chemicals in this kit, some cause skin and eye irritation. Wear protective clothing and eye or
face protection as needed.
DPD no. 1 chlorine test tablets are irritating to eyes, respiratory tract, and may cause allergic skin reaction. Provide
ventilation when handling and wear safety glasses and gloves.
Avoid all bodily contact with kit chemicals: some can be VERY HARMFUL to your health. Kit tests should be done only by
personnel who are properly trained and wearing chemical protective rubber gloves with inserts and industrial goggles or
protective mask. If exposed, follow FIRST AID INFORMATION inside kit lid or manual.
Alkaline chemical used in the mustard test is extremely hazardous. One drop of this liquid accidentally splashed into the
eye can cause permanent vision loss even if immediate first aid is applied. Immediately flush the eye with large amounts
of water for 20 to 30 minutes, if possible, with another person’s help.
Seek immediate medical treatment. If alkaline solution is swallowed, DO NOT induce vomiting. Dilute alkali by giving
water to drink, and seek medical treatment.

1-9.
CHEMICAL AGENTS: M272 WATER TESTING KIT.
Water samples are taken and test chemicals added to cause a change in color within test tubes and or a chemical coated
ticket. The color change is compared to a reference standard to determine hazardous levels of Lewisite, Nerve, Cyanide,
and Mustard agents. (See TM 3-6665-319-10.)

1-10.
TOTAL DISSOLVED SOLIDS METER.
Solids dissolving in a liquid leave ions suspended in that liquid. Ions conduct electrical current and can be used to
measure dissolved solids. The conductivity of a liquid is measured in microhms (µohm) and is directly proportional to the
total dissolved solids displayed by the meter in parts per million (milligrams per liter) (PPM (mg/l)).
A water sample is taken and placed inside the cell cup for test. The meter is set to the desired range and activated.
Reading is given in parts per million from an analog scale. A range extender is supplied for testing beyond the standard
meter range.

1-11.
TURBIDITY TEST SET.
Turbidity is a measurement of undissolved solids suspended in a liquid. A nephelometer emits a light beam into a liquid
sample and measures the amount of light reflected from undissolved solids. This measurement is automatically compared
to a stored measurement, usually taken from a known reference sample, and the difference is displayed by the meter in
Nephelometric Turbidity Units (NTU).
A probe is "zeroed" by immersing in a reference standard solution and activating the meter. The probe is then immersed
into the water being tested. Reading is given in Nephelometric Turbidity Units (NTU) on a digital display.

TM 10-6630-246-12&P
TM 09241B-12&P
1-12.
pH/TEMPERATURE TEST SET.
The concentration/activity of hydrogen ions in a liquid indicates how acidic (acid) or alkaline (base) the liquid is and
expressed as its pH value. pH is measured on a scale of 0 to 14 with 7 being neutral. A pH number less than 7 is acidic
and a number greater than 7 is alkaline.
The temperature probe senses actual temperature of the liquid being tested and provides temperature correction
information for accurate pH measurements.
The pH electrode and temperature probe is immersed in a reference standard pH solution and calibrated using the auto
calibration feature. The probe is then immersed into the water being tested. Temperature and pH readings are given on a
digital display.

COLOR COMPARATOR.
Water samples are taken and test chemicals added to cause a change in color. The color change is compared to a
reference standard color wheel through a comparator viewer to determine pH and chlorine content.

Section III. OPERATOR PREVENTIVE MAINTENANCE CHECKS AND
SERVICES (PMCS)
2-7.
GENERAL.
Preventive Maintenance Checks and Services means systematic caring, inspection, and servicing of
equipment to keep it in good condition and ready to use. As the operator, your mission is to:
(1) Be sure to perform your PMCS each time you use the Water Quality Analysis Set: Purification.
(2)
Do your "Before" PMCS just before you use the equipment.
(3)
Do your "After" PMCS right after using the equipment.
(4) Use DA Form 2404 (Equipment Inspection and Maintenance Worksheet) to record any faults that you
discover before, during, or after use, unless you can fix the fault. You DO NOT need to record faults that you fix.
2-8.
PMCS PROCEDURES.
a. Your Preventive Maintenance Checks and Services, table 2-1, lists inspections and care required to keep the
equipment in good operating condition.
b.
The "Interval" column of table 2-1 tells you when to do a certain check or service.
c.
The "Procedure" column of table 2-1 tells you how to do required checks and services.
NOTE
Terms "ready/available" and "mission capable" refer to same status: Equipment is on hand and ready to
perform its mission. (See DA Pam 738-750.)
d. The "Equipment Is Not Ready/Available If:" column in table 2-1 tells you when your equipment is non mission
capable and why it cannot be used.
e.
If the equipment does not perform as required, notify supervisor.
f.
If anything looks wrong and you can’t fix it, write it on your DA Form 2404 IMMEDIATELY, report it to your
supervisor.
g.
When you check for "operating condition", you look at the component to see if it is serviceable.

e. Calibration procedures. See figure 2-12.
NOTE
A one or two buffer calibration should be performed before pH is measured. It is recommended that a two
buffer calibration using buffers that bracket the expected sample range be performed at the beginning of
each day to determine the slope of the electrode. This serves the dual purpose of determining if the
electrode is working properly and storing the slope value in memory. Perform a one buffer calibration every
two hours during operation/testing to compensate for electrode drift.
There are two ways of calibrating the pH/temperature meter; auto calibration which recognizes the buffers
7.00, 4.00, and 10.00 included in the kit or manual calibration for use with buffers other than 7.00, 4.00,
and 10.00. The following procedures cover each method.
Table 2-4 lists and describes error codes that may be displayed during calibration and measurement.
If the meter does not function per the following procedures, see troubleshooting.
(1) Auto calibration with two buffers.
(a) Loosen cap on storage/soaker bottle (14) and slide bottle off electrode (11). Save for reuse.
(b)
If an air bubble is in electrode (11) tip, shake as you would a clinical thermometer to remove.
(c) Rinse two beakers (15) three times with demineralized or distilled water.
(d) Choose either 4.00 (16) and 7.00 (17) or 7.00 and 10.00 (18) buffers, whichever will bracket your expected
sample pH range.
(e) Open one each buffer capsule (19) and dissolve powder in beaker (15) with 3.4 oz (100 ml) demineralized or
distilled water. Use two stir rods (20), one for each, if needed.
(f) Rinse electrode (11) and probe (12) tip in demineralized or distilled water. Shake dry and place into lowest
prepared buffer solution.
(g)
Press power keypad (2) to turn meter on.
(h) While stirring gently, press cal keypad (4), CALIBRATE is displayed above the main readout and P1 is
displayed in the lower field. P1 indicates that the meter is ready for the first buffer. When the electrode (11) is stable the
ready prompt will be displayed and the temperature corrected pH value for the buffer is displayed. Press yes keypad (1).
The display will remain frozen for two seconds then P2 will be displayed in the lower field indicating the meter is ready for
the second buffer. Remove electrode and probe (12).

a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical and/or electrical
characteristics with established standards through examination (e.g., by sight, sound, or feel).
b. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics
of an item and comparing those characteristics with prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition, e.g., to clean
(includes decontaminate when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical fluids, or
gases.
d. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting the
operating characteristics to specified parameters.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
