Electronic Meter pH, ORP, EC, TDS, Salt Temperature

Without requiring additional reagents (tablets, drops, etc.), the Electronic Meters offer an absolutely professional way to measure various water values; such as, for example, conductivity, salinity (total dissolved solids), and pH value. The established value is displayed on the device within seconds after dipping the device in sample liquid. The sensitive electrodes, however, should always be kept damp. They should becalibrated at regular intervals, preferably before each measurement, by using a reference fluid. Both the batteries and the electrodes can be changed. The working range of the Electronic Meter is between 0 – 50°C; depending on the model temperature can be compensated for by determining the measurement value.
