Digital pH Controllers is easy with the Alpha pH 190 limit controllers. Featuring 6 sub-menus accessible via a four-button keypad for quick, easy setup and calibration, the controller/transmitters also come with two levels of password to protect against unauthorised tampering.For faster and more convenient control, choose the Alpha pH 190 which allows direct access to the set-point adjustment and calibration menus.
Features:

• Easy push-button calibration with USA/NIST buffer recognition for fast, effortless calibration. Controller freezes data transmission and relay activities during calibration and maintenance

• Symmetrical mode of operation for clear, uninterrupted readings even in electronically noisy environments

• Two SPDT relays with independent hysteresis – effective high/low set-points limit control with minimal relay-chattering

• Choice of automatic or manual temperature compensation. Three-wire system compensates error due to cable resistance

• 85 to 250 VAC. 50/60 Hz or DC variable input allows controller to be used with a wide range of supply voltages

• Full-scale 4 to 20 mA galvanically isolated current

• Ooutput for process control
