The PL-PH Series temperature probe is designed for use in a wide variety of applications that traditionally required a thermal well. The unit uses a corrosion-resistant brass or stainless steel housing with a substantially increased wall thickness, eliminating the need for a separate thermal well. The design of the probe also provides for a fast-time response. In most applications, the probe can be inserted directly into the liquid being measured, even corrosive liquids. The standard probe is available with a choice of thermistor or RTD sensor elements and a wide variety of resistance curves. Additional options include various probe lengths, thread type and size, and standard or custom wire or cable.
