Description
pH, ORP, Temperature In-line Controller. 1/8 DIN, RoHS compliant, panel mount pH/ORP/Temp controller with 2 sets of programmable on/off relay and backlight. Extremely price competitive.
- Easy to install 1/8 DIN plastic casing.
- Clear LCD displays pH, mV or temperature with backlight.
- Universal power supply input from 100 to 240 V AC.
- Automatic buffer recognition of US and NIST buffer sets. Calibrated data is stored in memory and ready to for use on power up.
- Automatic or manual temperature compensation.
- Displays absolute and relative ORP.
- Two sets of programmable on/off relays for pH or ORP & Isolated and reversible
4 to 20 mA current output for pH or ORP allows it to be used as a proportional output. - CE, RoHs compliant.
