6 SALINITY COMPENSATION: The t able below illustrates the change in the solubility of oxygen in air saturated water as a result of chloride concentration or salinity .
7 PROBE & MEMBRANE MAINTENANCE: The D.O. probe body is made of reinforced plastic for maximum durability. A thermistor temperature sensor provides temperature measurements of the tested sample. It is always recommended to keep the protective cap on the probe when not in use, to protect the membrane against damage and dirt.
The Platinum cathode should always be bright and untarnished. If it is tarnished or stained, due to contact with certain gases or a damaged membrane cap, the cathode should be cleaned. You can use a clean lint-free cardboard or cloth. Rub the cathode very gently side to side 4-5 times.
BATTERY REPLACEMENT: When the battery becomes weak the meter will display the low battery indicator " ". When this appears, only a few hours of battery life remain. A low battery will result in unreliable measurements. Prompt battery replacement is required.
