Digital Pocket Automotive Refractometer 300055
Measure concentrations in propylene glycol, ethylene glycol, battery acid and windshield washer fluid in the field with laboratory accuracy. Small, light and simple to use as optical refractometers, but with the precision of a digital readout. Reads samples as small as 1 mL. Sample temperature is initially displayed on the large LCD followed by the measurements results. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation and automatic shutoff (after 3 minutes). A sturdy water resistant case protects the electronics from wet environments and makes for easy clean ups.
Model features one button calibration to distilled water and indicates when the battery should be replaced (8000 readings). Comes ready to use with distilled water, transfer-pipet, "AAA" battery, instructions and carrying case.
Dimensions: 4 5/8" x 2 3/8" x 1 1/4"
Weight: 4.6 oz
Specifications
| Unit of Measure | Range | Resolution | Accuracy |
| Propylene Glycol | 32 (-50) F | 0.1 F | +/- 2.0 F |
| Ethylene Glycol | 32 (-50) F | 0.1 F | +/- 2.0 F |
| Battery Acid | 1.000 to (1.500) sg | 0.001 sg | +/-0.005 sg |
| *Windshield Washer Fluid | 14 (-40) F | 0.1 F | +/-2.0 F |
*Note: Windshield Washer Fluid is an aqueous cleaner used in a vehicle's automated spray system. It is not glass cleaner that is applied by hand and wiped with a towel. Windshield Washer Fluid is a mixture that may contain any or all of the following: detergent, methanol, propylene glycol, and silicone polymers.
The output of the refractometer is the freezing point of the windshield washer fluid.
