Hanna Instruments HI 2212 Flexible Calibration pH Meter, with Three Point Calibration

The HI 99141N is a pH and temperature benchtop meter suitable for lab use. The meter features pH and temperature probes, an LCD screen, manual or Automatic Temperature Compensation (ATC), and a Good Laboratory Practice (GLP) feature, which provides data consistency. A calibration expiration reminder can be set to alert the user when too much time has elapsed since the last pH calibration and a new one should be performed.

Calibration can be performed at up to three points using five standard (4.01, 6.86, 7.01, 9.18, 10.01) and two custom buffers, and calibration sachets are included.

pH range is -2.00 to 16.00 (+ or - 0.01 pH) with a resolution of 0.01 pH. Temperature range is -20.0 to 120.0 degrees C (-4.0 to 248.0 degrees F) + or - 0.2 degrees C (excluding probe error) with a resolution of 0.1 degrees C. Input impedance is 1012 Ohm and the device operates on a 12 VDC adapter. Dimensions are 235 x 222 x 109 mm (9.2” x 8.7” x 4.3’’), and weighs 1.3 kg (2.9 lbs.).

pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards.
