pH, Redox, Salinity, Conductivity, Oxygen and Temperature Meter / SD Memory Card

The pH-meter is a type of instrumentation for multiple capabilities for inspecting water quality. This portable pH-meter is used for controlling the value of pH, oxygen, salinity, conductivity and is also very suitable for measuring temperature. A 3-point calibration as well as automatic temperature compensation ensure great precision even with temperatures being measured that vary greatly. The pH-meter is delivered with a pH and conductivity probe included in the shipment. Different probes and a software with a data RS-232 cable are available as optional accessories. All recorded values can be stored directly on an SD card (up to 16 GB) in Excel format, or be transferred via the RS-232 interface in real time to a PC. For this latter, we offer as an optional software with a data RS-232 cable. This type of instrumentation is ideal for controlling water in swimming pools, aquariums, water treatment plants, etc.
