Battery/Coolant Tester (Hydrometer)

Features: Use the left scale for propylene glycol-based coolants and the right scale for ethylene glycol-based coolants to determine the freezing point. Not suitable for methanol-based coolants.
Applications: An optical instrument for checking the freezing point of coolant and washer fluid, and the specific gravity and charge status of battery fluid using light refraction.
Notes:
* Do not use for purposes other than the intended use.
* Use the left scale for propylene glycol-based coolants and the right scale for ethylene glycol-based coolants to determine the freezing point. Not suitable for methanol-based coolants.
* The reading for washer fluid is an approximate value.
* If the liquid to be measured is hot, wait for it to cool down before proceeding.
* Not suitable for cutting fluids.
