Dial thermometer for industrial temperature

This Ashcroft dial thermometer covers a range of -20 to 120 degrees F and -30 to 50 degrees C. The bi-metallic movement drives the pointer without external power. A 304 stainless steel housing and stem resist corrosion in harsh environments. A glass lens protects the dial face from impact and contamination.

Steady readings under continuous process conditions

The bi-metallic element responds directly to temperature change along the 4 inch stem. Sustained exposure within the rated range does not degrade the mechanical linkage. The 1/2 NPT back mount threads into a thermowell or piping for permanent installation. A NIST-traceable certificate confirms calibration accuracy at the time of shipment.

Verify connection and stem length before ordering

Confirm that your process fitting accepts a 1/2 inch NPT male thread. Ensure the 4 inch stem reaches the measurement zone inside the vessel or pipe. The back-mount orientation requires clearance behind the dial for installation and reading. No power supply or signal wiring is needed for operation.

Questions about this item

Does the 304 stainless steel stem transfer heat that could affect the -20 to 120°F reading during continuous use?

The bi-metallic movement is calibrated for the stated range; the 304 stainless stem and housing conduct process temperature to the sensor without electronic self-heating.

What fitting do I need on my pipe or vessel to install the 1/2 NPT back mount?

A female 1/2 inch NPT threaded port is required; the thermometer screws directly into that opening.

Will the 4 inch stem reach the flow in my existing 3 inch pipe tee?

The 4 inch stem extends from the back-mounted case; verify that the insertion depth places the tip in the fluid stream of your specific tee.
