Installation Location
The TB820D turbidimeter should be installed in a location:
• that is protected from direct sunlight and rain, i.e., the instrument should be installed indoors
or in a cubicle;
• that is subject to minimal mechanical vibration;
• where no corrosive gases are present;
• that is not exposed to high temperature and humidity. The temperature should be in the
range of -5 to 55°C, preferably at or around normal temperatures, and its fluctuation small.
The humidity should be kept between 10 to 90%RH. Prevent condensation which may
occur if the sample temperature is lower than the ambient temperature. Also, take protective
measures to prevent a sample and the tap water from freezing, if necessary;
• that provides adequate maintenance space and easy access for maintenance work; and,
• where the drain is provided.
