Hanna Instruments HI 96831 Digital Ethylene Glycol Refractometer

The HI 96831 is a portable, water resistant, digital ethylene glycol refractometer that utilizes the measurement of refractive index to determine the percent volume and freezing point of ethylene glycol based coolants or antifreeze. The meter helps eliminate the uncertainty associated with mechanical refractometers, and is suitable for field or lab use. Samples are measured after a simple user calibration with deionized or distilled water and within 1.5 seconds the instrument measures the refractive index of the sample and converts it to percent volume or freezing point. The meter features Automatic Temperature Compensation (ATC) between 0 and 40 degrees C/32 – 104 degrees F, and temperature is displayed (in C and F) simultaneously with the measurement on a large, dual-level LCD display along with icons for low power and other message codes. Auto-shut off feature turns the meter off automatically after three minutes of non use. Volume % range is 0 to 100% + or – 0.2% with a resolution of 0.1%. Freezing poi...
