The Dissolved Oxygen Meter is a true all-rounder for checking water quality. The portable data logger is used to control the water parameters pH, redox, conductivity, salinity, oxygen and is also very suitable for temperature measurement.
A 2-point calibration and an automatic temperature compensation guarantees high accuracy even with highly fluctuating measuring temperatures. The data logging meter is supplied with pH and conductivity probe. Different probes are available as accessories. All values can be stored directly on the SD card (1 ... 16 GB) as an Excel file or transferred via the RS-232 interface directly from the device to a PC. For this we optionally offer software and the suitable RS-232 interface cable as an accessory.
