Stainless steel 5 inch dial thermometer with glass window and 6 inch stem

Value Brand

Value Brand Bimetal Thermometer 5 in Dial 50 to 550F

SKU CH-2JNP-QKBZC

Measures 50 to 550 °F with a hermetically sealed 5-inch stainless-steel dial, ±1 % accuracy from 151 to 450 °F and ±1.5 % outside that range

  • Product typeEnvironmental & Mechanical
  • Wide 50–550 °F range covers diverse applications
  • ±1 % accuracy from 151–450 °F ensures reliable readings
  • ±1.5 % accuracy below 150 °F and above 451 °F maintains precision
  • Hermetically sealed stainless steel case resists moisture and corrosion
  • External adjustment allows quick field calibration

5 in Dial Bimetal Thermometer

This analog thermometer uses a bimetal sensing element in a hermetically sealed stainless steel case. The 5 inch dial displays temperatures from 50 to 550 Degrees F through a glass window. A 1/2 in NPT back connection and 6 in stem suit industrial process monitoring. External adjustment allows field calibration.

Accuracy and Environmental Performance

Accuracy is +/-1 Percent between 151 and 450 Degrees F. Outside that range, at 50 to 150 Degrees F and at 451 to 550 Degrees F, accuracy is +/-1.5 Percent. The stainless steel stem and case resist corrosion in harsh environments. Hermetic sealing prevents fogging and moisture ingress during normal operation.

Replaces Smaller or Less Accurate Dials

This unit replaces thermometers with smaller dials that are harder to read at a distance. It also upgrades from non-hermetic models that drift when exposed to humidity or wash-down cycles. The jump is worth it when a 5 inch face, 1/2 in NPT back mount, and external calibration are required for the application.

Questions about this item

How do I install the 1/2 in NPT back connection on a pipe, and what step is often missed?

Thread the 1/2 in NPT back connection into a matching female fitting, using thread sealant on the tapered threads. The step often missed is ensuring the 6 in stem fully inserts into the process flow so the sensing portion sits in the medium, not in the fitting cavity.

What maintenance will the hermetically sealed stainless steel case and glass window need over time?

The hermetically sealed case prevents internal moisture, so no internal servicing is required. Periodically clean the glass window and check the external adjustment for drift; if readings shift beyond the stated accuracy bands, replace the unit as the bimetal element cannot be recalibrated internally.

At what temperature does the accuracy tolerance widen first during sustained high-heat use?

At 451 Degrees F the tolerance widens from +/-1 Percent to +/-1.5 Percent, so sustained operation above 450 Degrees F is the first limit where accuracy degrades.
