Description
pH, Temperature In-line Analyzer. 1/4 DIN, IP65, panel mount pH/Temp analyzer with two sets of 2 wire 4 ~ 20 mA current output, 2 sets of programmable on/off relay, RS-485 output and backlight.
- Graphic LCD with manual backlight displays pH, temperature, relay status, and transmitter current mA output.
- Automatic buffer recognition of US and NIST buffer sets. Calibration data is stored in memory and is ready for use on power up.
- Two sets of isolated and reversible 4 ~ 20 mA current output for pH and temperature allows it to be used as a proportional output.
- 4 programmable on/off relays: 3 for pH and 1 for temperature.
- RS-485 output for remote access allows multiple units to be connected and ganged together.
- Password protection.
- IP65.
