The Right Features To Measure, Analyze And Control Conductivity, TDS And Temperature
- Accurate and stable readings.
- 3 programmable on/off relays: 2 for conductivity and 1 for temperature.
- Accepts 2-wire or 4-wire conductivity cells for K=0.1, K=1 and K=10 cell constants for improved flexibility and accuracy.
- Displays 3 selectable conductivity and TDS ranges per cell constant for a total of 18 ranges.
- Automatic temperature compensated (ATC) conductivity readings.
- Programmable temperature coefficient.
- Programmable hysteresis for customized control.
- Isolated and reversible 4-20 mA current output for conductivity. This output can be used as a proportional output.
- RS-485 output for remote access via an IBM compatible computer. This allows multiple units to be connected, ganged, together.
