Digital Battery and Antifreeze Tester

The REED INSTRUMENTS R9700 is a digital refractometer designed to check the freezing point of coolant in vehicle batteries. It provides readings for both Ethylene Glycol and Propylene Glycol solutions. The tool gives a direct measurement of antifreeze protection levels.

Automotive Technicians and Vehicle Owners

This suits anyone who needs to verify coolant concentration quickly without using a traditional optical eyepiece. It is not for users who require a laboratory-grade instrument with a wider measurement range or data-logging capability. Buyers needing to test other fluid types such as diesel exhaust fluid or windshield washer fluid should look at a different device.

Questions about this item

What is the first limit reached during sustained use of the R9700?

The R9700 runs on battery power, so extended testing sessions are limited by the battery charge remaining in the unit.

How much noise or heat does the R9700 produce when running all day?

The digital refractometer has no moving parts and draws very little power, so it operates silently and generates no noticeable heat during continuous use.
