Product Description
Hanna Instruments HI 99181N Skin pH Meter: Industrial & Scientific. The device operates on three 1.5V AAA batteries and turns off automatically after eight minutes of non-use. The HI 99181 is a portable, microprocessor-based pH and temperature meter with a flat surface probe suitable for skin pH measurement. The meter features replaceable pH and temperature probes, an LCD screen, and Automatic Temperature Compensation (ATC). A built-in temperature sensor allows simultaneous temperature compensated pH and temperature readings and an integral pH sensor preamplifier provides measurements impervious to noise and electrical interferences. Calibration is automatic at one or two points with two sets of memorized buffers (Standard 4.01, 7.01, 10.01 pH or NIST 4.01, 6.86, 9.18 pH), and calibration sachets are included. pH range is -2.00 to 16.00 (+ or - 0.02 pH at 20 degrees C/68 degrees F) with a resolution of 0.01 pH. Temperature range is -5.0 to 105.0 degrees C (23.0 to 221.0 degrees F) + or - 0.5 degrees C (up to 60 degrees C) and 1.0 degrees C (outside); 1.0 degrees F (up to 140 degrees F) and 2.0 degrees F (outside) with a resolution of 0.1 degrees C (0.1 degrees F). Dimensions are 152 x 58 x 30 mm/6.0” x 2.3” x 1.2’’ (H x W x D), and weighs 205 g (7.2 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.
