The Phoenix Systems CoolantStrip tests an engine's coolant fluid while following MAP, ASL and ASTM guidelines for coolant specifications. With CoolantStrip, service centers can have a clear visual to show customers indicating when coolant correction or replacement is necessary. CoolantStrip measures the pH level and glycol percent of engine coolant. Because CoolantStrip uses a proprietary integrated Glycol color metric scale, it can be used with all coolant colors, including conventional coolant as well as long life, extended life, Dex Cool and Low Tox coolants.
