Product Description

Hanna Instruments HI 2221N Calibration Check pH/ORP/Temperature Benchtop Meter: Industrial & Scientific. Input impedance is 1E12 Ohms and the device operates on a 12 VDC adapter. The HI 2221 is a pH , Oxidation Reduction Potential (ORP), and temperature benchtop meter featuring calibration check diagnostics for pH electrodes and buffer solutions during calibration. The function notes if the device is properly calibrated, and provides a calibration range warning to notify the user if a reading appears too far from the calibration periphery. The instrument can measure using Oxidation Reduction Potential (ORP) electrodes due to its capability to measure mV with a resolution up to 0.1 mV. The meter features five point calibration with seven memorized buffers (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45), Manual or Automatic Temperature Compensation, and Good Laboratory Practice (GLP) capabilities that allow storage and retrieval of all pH related data. It has a logging capability of up to 100 points. A built-in logging function stores measurements in non volatile memory and can be transferred to a PC through a USB port. pH range is -2.00 to 16.00 pH (+ or – 0.01 pH) with a resolution of 0.01 pH. mV range is + or – 699.9; 2000 mV (+ or – 0.2 mV; 1 mV) with a resolution of 0.1; 1 mV. Temperature range is -20.0 to 120.0 degrees C (+ or - 0.2 degrees excluding probe error) with a resolution of 0.1 degrees C. 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.
