The HI 96832 Digital Refractometer is a rugged portable, water resistant device that utilizes the

measurement of refractive index to determine the % volume and freezing point of propylene glycol

based solutions.

Propylene glycol is used in many applications including:

• pharmaceutical solvent

• humectant food additive

• emulsification agent

• moisturizer in cosmetics, toothpaste, tabacco products, etc.

• hand sanitizer and lotion

• antifreeze

The HI 96832 device benefits from Hanna’s years of experience as a manufacturer of analytical

instruments. The digital refractometer eliminates the uncertainty associated with mechanical

refractometers and is easily portable for use in the field.

The HI 96832 refractometer is an optical device that is simple and quick to use. Samples are

measured after a simple user calibration with distilled or deionized water. Within seconds, the

refractive index and temperature are measured and converted into one of two measurement units;

% Volume or Freezing Point. The instrument utilizes internationally recognized references for unit

conversion and temperature compensation for propylene glycol solutions (e.g. CRC Handbook of

Chemistry and Physics, 87

th

Edition).

The temperature (in °C or °F) is also displayed on the large dual level display along with helpful

message codes.

Key features include:

• IP65 waterproof protection

• Automatic Temperature Compensation (ATC)

• Battery operation with Low Power indicator (BEPS)

• Automatically turns off after 3 minutes of non-use
