ZORO SELECT Bimetal Thermometer
This ZORO SELECT dial thermometer measures temperatures from 0 to 250 degrees Fahrenheit and -20 to 120 degrees Celsius. It features a 5 inch dial diameter and a 4 inch stem with a 1/2 inch NPT connection. The housing uses 304 stainless steel and the lens is glass. An adjustable angle allows flexible mounting for environmental and mechanical checks.
HVAC Technicians and Plant Operators
The wide Fahrenheit and Celsius range suits technicians monitoring pipes, tanks or ducts up to 250 degrees Fahrenheit. The 4 inch stem reaches into standard fittings and the adjustable head eases reading from awkward positions. Buyers who need a longer insertion depth or a digital output for data logging should look at a different instrument.
5 Inch Dial with 4 Inch Stem
The 5 inch dial diameter provides clear visibility of the dual scale markings across the full 0 to 250 degree Fahrenheit span. The 4 inch stem length and 1/2 inch NPT thread determine whether the unit fits the specific process connection. Confirm these dimensions match the installation before ordering.

Questions about this item
How do I install the 1/2 in NPT stem correctly?
Thread the 4 in stem into a 1/2 in NPT fitting, then rotate the adjustable-angle dial to the viewing position before final tightening to avoid stressing the glass lens.
What maintenance will the bimetal element need over time?
The 304 stainless steel housing and glass lens resist corrosion, but the bimetal coil can drift; plan to verify accuracy against a known reference annually and replace if readings shift beyond your tolerance.
At what temperature does the dial reach its limit during sustained use?
The scale stops at 250 °F (120 °C); continuous exposure near that upper end will peg the pointer and risks permanent calibration loss.
