New PVC-insulated probes are ideal for quick readings in hard to reach areas. With exposed junctions, probes have a time constant of 3 seconds; response time is 15 seconds. Small diameter 24-gauge (0.020" dia) wire probes are 3-ft long. Probes include rubber strain relief and ANSI color-coded miniconnector. All insulated-wire probes include straight insulated cable with no handle and feature ANSI color-coded miniconnectors: type J—black, type K—yellow, type T—blue, and type E—purple. Fiberglass- and ceramic-insulated probes have exposed junctions; use for high-temperature applications. Note: Exposed-junction probes are not recommended for use with aqueous solutions. Do not subject type J exposed-junction probes to moisture—iron will rust.
