Product Description

Hanna HI21211 is a wall mounted, microprocessor-based pH digital controller engineered for industrial process control and laboratory applications where precision and reliability are critical. Featuring dual setpoint operation, the HI21211 controller ensures targeted pH management for water treatment, chemical processing, and manufacturing environments.

The controller supports On/Off dosing control and has built-in fail safe alarm technology to protect against power supply failures or signal interruptions—these conditions are visually indicated by a front-panel red LED. Automatic temperature compensation is provided using a Pt100 temperature probe, guaranteeing accurate readings across a wide temperature range.

Microprocessor-based pH controller with dual setpoint for advanced process regulation.
Analog output options: 0–1 mA, 0–20 mA, 4–20 mA, 0–5 VDC, 1–5 VDC, 0–10 VDC for flexible integration.
Electromechanical relay SPDT contact outputs, fuse-protected for dosing and system alarms.
Dosing control terminals, maximum relay ON time adjustable from 1 to 60 minutes.
Automatic, one, two, or three-point pH calibration at 4.01, 7.01, and 10.01 pH.
Power supply: 115 VAC ±10%, 15 VA power consumption.
GLP features: storage of calibration date, time, offset, slope, and buffers.
IP54 protection rating, designed for quick wall mounting and robust industrial service.
