DO sensor pH/ORP sensor Protection sleeve Calibration beaker PRELIMINARY EXAMINATION SPARE PARTS Remove the probe/sensors from the packing material and examine it carefully to make sure that no damage has occurred during shipment. If there is any damage, please contact your local Hanna Instruments Office. HI769828/4 Note Conserve all packing material until the product has been observed to function correctly. Any defective item must be returned in its original packing. HI769828/20 Probe body with temperature sensor & 20 m cable HI769828 is the multisensor probe for HI9828. The probe has been designed to resist to all harsh operating conditions. It is very easy-to-use and can be installed for direct pipe measurements. The protection sleeve allows to dip the probe for a long period without damaging the sensors and the calibration beaker permits to perform maintenance operations directly on field. Calibration data are stored in the probe internal memory, so that sensors can be changed without needing recalibration. The user can disconnect all sensors separately for a better cleaning and to change the probe body, if for example a different cable length is required.

Blue Stainless Steel AISI 316 Body:PVC 111 x 14 Ø mm INSTALLATION D.O. sensor The temperature sensor built near the galvanic D.O. sensor allows stable temperature compensated D.O. readings in a few seconds. The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter. Oxygen that passes through the membrane causes a current flow, from which the oxygen concentration is determined. The D.O. sensor is shipped dry. Activate it before installing the probe. To hydrate the sensor and prepare it for use proceed as follows: • Remove the black & red plastic cap. This cap is used for shipping purposes only and can be thrown away. • Insert the O-ring in the membrane. • Rinse the membrane with HI7042S electrolyte solution while shaking it gently. Refill with clean electrolyte. Gently tap the membrane over a surface to ensure that no air bubbles remain trapped. To avoid damaging the membrane, do not touch it with your fingers. • With the sensor facing down screw the cap clockwise to the end of the threads. Some electrolyte will overflow. • Insert the sensor in the probe body with the right alignment to the corresponding white connector. • With the supplied tool screw the locking nut to fix the sensor. Conductivity sensor The conductivity sensor uses the 4-ring technology that allows stable and linear readings without any interference in the whole range. • Insert the sensor in the probe body with the right alignment to the corresponding blue connector. • With the supplied tool screw the locking nut to fix the sensor. pH and pH/ORP sensor The pH and pH/ORP sensors are gel filled and feature cloth junction, glass and Pt sensors respectively. The external plastic body is built to last even in harsh environmental conditions. • Insert the sensor in the probe body with the right alignment to the corresponding red connector. • After mounting the sensors, screw the protection sleeve for taking measurements or the transparent beaker for performing calibration. • With the meter off, connect the probe to the DIN socket on the bottom of the meter by aligning the pins and pushing in the plug. Tighten the nut to ensure a good connection. PROBE MAINTENANCE General maintenance After use, rinse the probe with tap water and dry it. The pH electrode bulb must be kept moist, while the D.O. and EC sensors should be stored dry. Maintenance of D.O. sensor For a top performance probe, replace the membrane every 2 months and the electrolyte once a month. Proceed as follows: • Unscrew the membrane by turning it counterclockwise. • Rinse the spare membrane with some electrolyte while shaking it gently. Refill with clean electrolyte. • Gently tap the membrane over a surface to ensure that no air bubbles remain trapped. • With the sensor facing down, screw the cap clockwise to the end of the threads. Some electrolyte will overflow. If any deposit scales the sensors, gently brush the sensor surface with the brush supplied in the maintenance kit, while paying attention to not damage the plastic body. Maintenance of EC sensor After every series of measurements, rinse the probe with tap water. If a more thorough cleaning is required, clean the probe with the brush supplied in the maintenance kit or a nonabrasive detergent. After cleaning the probe, always recalibrate the instrument. Maintenance of pH & pH/ORP sensors • Remove the protective cap. Do not be alarmed if any salt deposits are present. This is normal with electrodes and they will disappear when rinsed with water. • Shake the electrode down as you would do with a clinical thermometer to eliminate any air bubbles inside the glass bulb. • If the bulb and/or junction are dry, soak the electrode in HI70300 storage solution for at least one hour. • To minimize clogging and ensure a quick response time, the glass bulb and the junction should be kept moist and not allowed to dry. • Replace the solution in the protective cap with a few drops of HI70300 storage solution. Tap water may also be used for a very short period (couple of days). NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WATER. • Inspect the electrode for scratches or cracks. If any present, replace the electrode. • Cleaning procedure: clean frequently the probe by soaking it for 1 minute in HI70670 or HI70671 cleaning solutions. After performing this procedure, soak the electrode in HI70300 storage solution before taking measurements.
