Value Brand 5 in Dial Thermometer 0 to 250 F

Bimetal Dial Thermometer for Industrial Use

This bimetal thermometer measures temperature from 0 to 250 degrees Fahrenheit and -20 to 120 degrees Celsius. A five-inch dial provides clear readings for HVAC, plumbing, or process-monitoring tasks. The 304 stainless-steel housing and glass lens resist corrosion in demanding environments. A four-inch stem with a half-inch NPT bottom connection fits standard fittings.

Installation and Common Issues

Thread the half-inch NPT stem directly into a pipe or vessel fitting using appropriate sealant. Ensure the sensing portion sits fully in the media flow for accurate response. Over-tightening can damage threads or crack the housing, so apply moderate torque. Vibration may loosen the connection over time; periodic checks prevent leaks or reading drift.

Temperature Range Decides Suitability

The 0 to 250 degree Fahrenheit span determines whether this instrument covers your process limits. Applications exceeding 250 degrees Fahrenheit or requiring sub-zero accuracy below -20 degrees Celsius need a different range. The included NIST-traceable certificate supports calibration records for quality systems. Buyers needing a wider span or digital output should select another model.
