The instrument is a microprocessor-based pH, ORP, Conductivity, TDS and Temperature bench meter. Relative mV feature is also provided. The autoranging feature of the Conductivity and TDS ranges automatically sets the instrument to the scale with the highest resolution.
pH measurements are compensated for temperature effect automatically (ATC) using a temperature probe, while the EC readings can be compensated automatically (ATC) using the conductivity probe with built-in temperature sensor or manually (MTC). It is also possible to disable the temperature compensation and measure the actual conductivity.
The temperature coefficient is user selectable. The pH calibration can be performed at 1, 2 or 3 points with five memorized buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01). In addition, the instrument is provided with calibration timeout alarm, GLP feature to view last calibration data and automatic HOLD feature to freeze the first stable reading on the LCD.
