Industrial thermometer for HVAC

This liquid-in-glass thermometer covers a range of 30 to 240 degrees Fahrenheit and 0 to 110 degrees Celsius. The adjustable-angle body lets operators position the 9-inch scale for clear reading in tight mechanical rooms or on piping runs. A 1 1/4 inch -18 male UNEF shank threads directly into standard thermowells for permanent installation.

Replaces fixed-angle glass thermometers on boilers

The adjustable head eliminates the need to re-pipe when sight lines change after equipment rearrangement. Graduations of 2 degrees Fahrenheit and 1 degree Celsius give sufficient resolution for hydronic balancing and refrigerant checks. The upgrade is worth it when maintenance teams need to read temperature from multiple angles without removing the instrument.

Limited by liquid-in-glass physics and UNEF mounting

The blue spirit fill cannot be read remotely or logged, so supervisory systems still need a separate sensor. Glass construction restricts use to non-vibrating, non-corrosive media and pressures compatible with the thermowell. The 1 1/4 inch -18 UNEF thread does not fit NPT or metric ports without an adapter.

Questions about this item

What thread size fits the 1 1/4 In. -18 Male UNEF connection on this thermometer?

The thermometer has a 1 1/4 In. -18 Male UNEF shank, so you need a matching female UNEF fitting with the same 18 threads per inch.

How do you set the adjustable angle after threading it in, and what step is often missed?

Thread the straight shank into the port, then rotate the case to the desired viewing angle and lock it; the step often missed is tightening the lock nut after positioning.

When should the liquid-in-glass column be replaced instead of just recalibrated?

Replace the unit if the liquid column separates, appears cloudy, or the glass cracks, since a liquid-in-glass thermometer cannot be field-recalibrated once the fluid integrity is lost.
