Note: Save all packing material until you are sure that the instrument functions correctly. Any defective item must be returned in its original packaging with the supplied accessories.

GENERAL DESCRIPTION

With HI 93703-11 turbidity measurements can be performed with high precision in the field as well as in the laboratory. HI 93703-11 turbidity meter is a microprocessor-based instrument used to determine the turbidity of water and waste-water. The meter covers a 0-1000 FTU range in two scales: 0.00 to 50.00 FTU and 50 to 1000 FTU. The autoranging feature of the instrument sets the appropriate range for the measurement.

HI 93703-11 also includes a real-time clock and log-on-demand capability. The PC communication is made through a serial port of your computer and the 5-pin socket on the meter.

Note: HI 93703-11 has been designed according to the ISO 7027 International

Standard, consequently the turbidity measurement units are expressed in

FTU (Formazine Turbidity Unit). FTU is identical to the other internationally recognized unit: NTU (Nephelometric

Turbidity Unit).

The meter is housed in a rugged and lightweight case, with an easy-to-read LCD.

To save battery-life, the instrument is equipped with an automatic shut-off feature which is activated after 5-minutes of non-use. This feature is disabled when the meter is connected to the serial port of the computer.

All operations can be carried out with only five keys and troubleshooting functions can be performed with displayed error code guides.

A positive-locking system guarantees that the cuvet is firmly placed in the cell.

The keypad is water-resistant and can be wiped with a moist cloth for quick cleanups.

Two or three point calibration (0,10, 500 FTU*) can be easily performed using available standards, and the last calibration date is automatically stored for future retrivial.

We have chosen 10 FTU * as the standard calibration point because it best fits the water turbidity measurements in different applications, from drinking water to wastewater treatment.

HANNA instruments

®

uses the primary standard AMCO-AEPA-1 to avoid all formazinerelated problems. Formazine is a toxic, unstable substance, which requires particular care: its standards have to be prepared only a few minutes before performing the calibration, and cannot be reused because of their short life.

HANNA instruments

®

standards are extremely stable, can be reused, and last up to six months, if free from contamination.

HI 93703-11 can be used with both standards.

Battery replacement must only take place in a safe area and using 1.5V AA alkaline batteries.

To install or replace the batteries, turn the unit off and remove the battery compartment cover on the raer of the meter.

POTS

Insert the new batteries while paying attention to the polarity.

After the batteries have been installed, close the battery cover and make sure the gasket is in place before tightening the 2 screws, to ensure a watertight seal.

PC CONNECTION

To communicate with the instrument through the HI 92000 software, use the HI 920011 cable

(optional) to connect a serial port of your computer to the 5 pin connector of the meter.

When connected the meter will maintain full functionality, being able to perform a data transfer while the meter is being operated.

Notes:

• Serial communication is not allowed when the meter is being calibrated.

• The auto shut-off feature is also disabled when the meter is connected to a computer.
