The Right Features To Measure, Analyze And Control pH And Temperature
- Accurate and stable readings.
- 5 programmable on/off relays: 4 for pH and 1 for temperature.
- Manual or automatic temperature compensated (ATC) pH readings.
- Programmable hysteresis for customized control.
- Isolated and reversible 4-20 mA current output for pH. This output can be used as a proportional output.
- DC voltage output for pH/ORP pre-amplifier.
- RS-485 output for remote access via an IBM compatible computer. This allows multiple units to be connected, ganged, together.
