DIGITAL BATTERY/ANTIFREEZE TESTERS
(REFRACTOMETERS)

TWO (2) MODELS TO CHOOSE FROM (DR-GLYCOL (°F)
AND DR-GLYCOL (°C))

Applications: *Determination of battery coolant status: Good, Fair, Recharge
*Indicates specific gravity, freezing point temperature and battery charging level
*Scales for Ethylene Glycol and Propylene Glycol *Provides accurate readings
 within seconds *Checks freezing point temperature of cars, trucks, solar systems,
and standby battery stations *Only a few drops required for accurate measurement

Features: *Small sample required 0.4mL *Automatic Temperature Comp. *Stainless steel plate for optical sample prism *Use on sample temp. up to 100°C *5 Year Warranty

These testers are easy to use; just put a few drops of radiator coolant or battery fluid on the
instrument prism plate to obtain a direct reading of degrees antifreeze protection or battery
condition. That's all there is to it. Easier than any other method and more convenient. Takes
just a few seconds. These testers can be used for both Ethylene Glycol and Propylene Glycol
type antifreezes.

Measure percent concentrations in the field or plant with laboratory accuracy. As small, light
and simple to use as optical refractometers but with a digital readout (0.75" LCD display) to
eliminate misreadings that can occur with the optical refractometer. The sophisticated
microprocessor provides automatic calibration, automatic shutoff after 3 minutes, a low battery
indicator, and a low power consumption resulting in over 2,000 tests per battery. Water resistant
design protects the electronics from wet environments and makes for easy clean ups. This
model features automatic temperature compensation. Model comes with battery, instruction
book and carrying case.
