Jenco 6312PTB - pH / Temperature Controller

Jenco 6312PTB pH/Temperature Controller

pH/mV analyzer, dual current isolated reversible transmitters, RS-485, relays 2 high, 1 low and 1 temp.

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.
