Value Brand 1NFZ1 Bimetal Thermometer 3 in Dial 50 to 550 F

Professional Temperature Measurement

The Value Brand 1NFZ1 bimetal thermometer provides direct temperature readings from 50 to 550 degrees Fahrenheit and 10 to 290 degrees Celsius. Its three-inch glass lens dial mounts on a six-inch stem with a half-inch NPT back connection for secure installation in tanks or pipelines. The 304 stainless steel housing resists corrosion in industrial and commercial environments. This instrument suits technicians who need a durable, analogue sensor for process monitoring.

Thermals Noise and Power Draw

As a purely mechanical bimetal device, the thermometer operates without any electrical supply and therefore produces zero power draw and no audible noise. The stainless steel stem conducts process heat to the coiled sensing element, moving the pointer across the calibrated dial without electronic drift. Because no circuitry is present, there is no self-heating effect to offset, and the housing remains at process temperature during normal use. Operators can rely on consistent indication in high-vibration settings where powered sensors might fail.

Bundled Accessories and Software

The unit ships without a NIST-traceable calibration certificate, so users requiring documented traceability must arrange third-party verification separately. No mounting hardware, thermowells, or configuration software are included in the package. The half-inch NPT thread allows direct fitting to standard process connections, but any required seals or adapters must be sourced independently. Buyers who need immediate certified accuracy or a complete installation kit should plan for additional procurement.
