Product Description
Calcium chloride brines are used for de-icing, refrigeration and dust control, and knowing their freeze protection is essential. This hydrometer reads both specific gravity and the corresponding freezing point, so you can confirm a solution will perform at the temperatures it needs to face through the season.
This listing is for catalog number 6611-3: Calcium Chloride Hydrometer, Specific Gravity/Freezing Point. The glass hydrometer is calibrated at 15°C (60°F) and measures specific gravity from 1.000 to 1.280 in 0.002 steps. A second scale shows freezing point from 30 down to -40°F in 5 degree increments. At 305 mm long, it fits standard hydrometer jars and needs no power or calibration fluids. LIGHT LABS stocks the Heathrow Scientific line, so racks, replacement parts and consumables are easy to reorder.
Key Features
