Overview
The Hanna HI-2211 is a reliable benchtop meter built for testing pH, mV, and temperature in laboratories. It comes with a clear LCD screen and digital push-buttons for easy daily operation. The device runs on a standard 12V power supply and includes an electrode holder for secure bench placement. It delivers high accuracy for routine research and quality control tasks.

Dual Measurement Modes: This device reads both pH levels and millivolt values in one single machine and lets technicians handle regular liquid testing and oxidation checks on the same work desk.
Extended pH Scale: Its internal software processes readings across a broad scale running from negative 2.00 up to positive 16.00 pH units to cover extreme acid or base solutions.
High Precision Decimal: Its screen updates measurements down to exact 0.01 pH increments and gives lab workers the sharp accuracy required for strict chemical research and medical testing.
Dual Range Millivolt Detection: Its system switches automatically to measure millivolts across a low span of plus or minus 399.9 mV and a high span reaching up to plus or minus 2000 mV.
Wide Temperature Measurement: A separate probe measures liquid heat levels starting from negative 9.9 degrees all the way up to 120.0 degrees Celsius during active testing tasks.
Digital LCD Screen: Its wide front screen displays your active pH reading on the main line while showing the sample temperature at the same time on the lower line.
Calibration Setup System: Its meter runs automated calibration routines using five preprogrammed standard buffer values to make daily setup fast and clear for new operators.
Active Reading Stability: A small hourglass icon blinks on the screen while the sensor stabilizes and stops moving once the reading locks in so you know exactly when to write down the data.
Onboard Data Memory Storage: You can save readings directly inside the machine memory by pressing the dedicated save button on the front control pad.
12 Volt Power Adapter: Its unit plugs into a wall outlet using a safe 12 VDC power brick rather than running on internal batteries, keeping power stable during long testing shifts.
