Product Identity

The Value Brand 1NFZ4 is a bimetal dial thermometer built for industrial and HVAC professionals who need reliable local temperature indication without power. Its 3 inch dial and 2.5 inch stem suit panel mounting or direct immersion in pipes and ducts.

Range and Resolution

The instrument reads from 0 to 250 degrees Fahrenheit and from minus 20 to 120 degrees Celsius, covering common heating water steam and refrigeration lines. Outside that span the pointer saturates so the user must select a different range for higher or lower processes.

Upgrade Context

It replaces aging glass stem thermometers or uncalibrated dial gauges where a NIST traceable certificate is now required for compliance. The jump is not worthwhile if the application demands electronic logging remote transmission or a narrower span with finer graduations.

Questions about this item

Will the 1/2 in NPT stem thread into my existing 2.5 in immersion well?

The stem is 2.5 in long with a 1/2 in NPT connection, so it fits standard wells of that thread size and insertion depth.

How can I verify the dial reads correctly across the 0 to 250 F range after installation?

Compare the pointer against a known reference at several points between 0 and 250 F; the included NIST-traceable certificate confirms factory calibration.

Does the box contain a thermowell or mounting hardware for the 3 in dial?

The package includes the thermometer with 304 stainless steel housing and glass lens only; a thermowell or additional fittings must be sourced separately.
