Description
1/4 DIN, IP65, panel mount pH/ORP/Temp analyzer with 4 to 20 mA current output and 2 sets of programmable on/off relay. Extremely price competitive.
- Clear LCD displays pH or mV, with temperature and relay status simultaneously.
- Automatic buffer recognition of US and NIST buffer sets. Calibration data is stored in memory and is ready for use on power up.
- Displays absolute and relative ORP.
- Isolated and reversible 4 to 20 mA current output for pH or ORP allows it to be used as a proportional output.
- 2 programmable on/off relays: 2 for pH or ORP.
- CE Approved
- Password protection.
- IP65
