These general purpose probes are designed for use with liquids, gases and semisolids. The small-diameter probes provide quick readings in hard to reach areas. Response Time: 1.7 seconds or greater. Acrylonitrile butadiene styrene (ABS) handles provide a light weight design for ease of use along with durability. Probe handles feature a strain relief spring that protects the cable connection against damage due to repeated flexing and tugging. Each probe comes with color coded ANSI miniconnectors: type J-black, type K-yellow, type T-blue, and type E-purple.
