The Hanna Instruments Hi99181 is a durable, waterproof, and portable pH and temperature meter designed specifically for analysis of skin. Automatic calibration is performed at one or two points with two sets of buffers. All calibration and measurement readings are automatically compensated for temperature variations.
PH Range : -2.00 to 16.00 pH PH Resolution : 0.01 pH PH Accuracy : ±0.02 pH PH Calibration : one or two-point calibration, two sets of standard buffers available (4.01, 7.01, 10.01 or NIST 4.01, 6.86, 9.18) PH Temperature Compensation : automatic from -5.0 to 105.0°C (23 to 221°F) Temp.
