Value Brand Bimetal Thermometer 5 in Dial 0-250°F 2.5 in Stem

SKU CH-VZW0-QS7EH

Measures 0 to 250 °F with a 5 in dial, 2.5 in stem and 304 stainless steel housing

  • TypeEnvironmental & Mechanical
  • Wide 5 in dial for easy reading
  • Dual scale 0-250 °F and -20 to 120 °C
  • 5 in stem fits standard 1/2 in NPT fittings
  • 304 stainless steel housing resists corrosion
  • Glass lens protects dial in harsh environments

Purpose & Audience

This bimetal thermometer measures temperatures from 0 to 250 degrees Fahrenheit and -20 to 120 degrees Celsius. The 5 inch dial provides clear readings for industrial or commercial monitoring tasks. A 2.5 inch stem with 1/2 inch NPT bottom connection fits standard process fittings. It suits technicians who need a direct-reading instrument without electronic components.

Thermals Noise Power

The all-mechanical bimetal element operates without a power supply, so it draws zero current and produces no audible noise. A 304 stainless steel housing resists corrosion in harsh environments. The glass lens protects the dial face while maintaining visibility. Performance stays consistent across the full calibrated range without drift from electrical interference.

Build Integration

The 1/2 inch NPT bottom mount threads directly into pipes, tanks or thermowells, requiring no brackets or adapters. A 2.5 inch stem length reaches into the process media while keeping the dial outside the vessel. The unit ships with a NIST-traceable calibration certificate, so installers can document compliance immediately. No wiring, software or external power is needed for operation.

Questions about this item

How do I install the 5 in dial thermometer with its 1/2 in NPT bottom connection without cross-threading?

Screw the 2.5 in stem into the 1/2 in NPT fitting by hand until snug, then tighten one full turn with a wrench on the hex; the glass lens and 304 stainless housing must not be used as leverage points.

What part of this thermometer will need replacement first and how often?

The bimetal coil inside the 304 stainless stem can drift over time; plan to verify accuracy against a known reference annually and replace the unit if readings shift beyond your process tolerance.

At what temperature does the 0 to 250°F range limit continuous use?

Sustained exposure near the 250°F upper mark accelerates coil fatigue and can stress the glass lens seal, so operate below that ceiling for maximum service life.
