Product Description
Hanna Instruments HI 98172N pH/ORP/ISE Meter: Industrial & Scientific. Input impedance is 1E12 Ohms and the device operates on four 1.2V AA rechargeable batteries. The HI 98172 is a portable pH, Oxidation Reduction Potential (ORP), Ion Selective Electrode (ISE), and temperature meter suitable for field use. The meter features five-point calibration with seven standard (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45) and five custom buffers. It can also measure with ISE electrodes on a ppm scale. The instrument includes replaceable pH and temperature probes, an LCD screen, and Manual or Automatic Temperature Compensation. Diagnostics provide a reminder when a new calibration is necessary and a calibration range warning to notify the user if a reading appears too far from the calibration periphery. The diagnostics also monitor electrode aging and alert user when the electrode needs cleaning. It also has a Good Laboratory Practice (GLP) feature to view last calibration data for each range, logging capability of up to 50 samples on each range, and a PC interface. pH range is -2.00 to 16.00 pH + or – 0.01 pH at 20 degrees C with a resolution of 0.01 pH. mV range is + or – 699.9; 2000 mV (+ or – 0.2 mV; 1 mV at 20 degrees C) with a resolution of 0.1; 1 mV. Temperature range is -20.0 to 120.0 degrees C + or - 0.4 degrees C (0.8 degrees F) at 20 degrees C (excluding probe error) with a resolution of 0.1 degrees C (0.1 degrees F). Dimensions are 196 x 80 x 60 mm/7.7” x 3.1” x 2.4’’ (H x W x D), and weighs 425 g (15 oz.). 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.
