The Hanna HI 2211 is a microprocessor-based pH, mV and Temperature bench meter.
This instrument is equipped with a large easy-to-read LCD which shows the pH ( or mV) and temperature simultaneously, together with graphic symbols.
The HI 2211 can also measure ion concentration ( ISE) and Oxidation Reduction Potential ( ORP) in the mV range.
The calibration process is guided step by step through clear indications on the LCD. A stability indicator makes the calibration procedure error-free.
pH measurements are compensated for temperature effect manually or automatically with the HI 7662 temperature probe.
The HI 2211 is supplied with HI 1131B glass-body combination pH electrode with 1 m ( 3.3' ) cable, HI 7662 temperature probe, HI 76404 electrode holder, pH 4.01 & 7.01 buffer solutions ( 20 mL ea.) , HI 7071S electrolyte solution, 12 Vdc power adapter and instruction manual.
