Product identity

The Value Brand 23NU30 is a 5 inch stem analog dial pocket thermometer covering a 25 to 125 degrees Fahrenheit range. It is built for technicians and inspectors who need a simple, battery free way to spot check air, liquid or surface temperatures in the field or on the bench.

Thermals noise power

The stainless steel stem and polycarbonate lens withstand the measured range without electronic drift or self heating because the mechanism is purely mechanical. No power source is required so there is no electrical noise, no battery drain and no warm up time before the first reading.

Build fit

The one inch dial fits in a shirt pocket or tool pouch and the five inch stem reaches into ducts, tanks or machinery openings where a probe must stay clear of moving parts. The instrument ships without a NIST traceable certificate so users who require documented calibration will need to arrange that separately. Buyers who need a wider temperature span, a digital display or data logging should choose a different instrument.

Questions about this item

How do I install the 5-inch stem into a process and what step is often missed?

Insert the stem at least 2 inches into the medium, wait for the dial to stabilise, and remember to calibrate using the hex nut on the back before first use.

What maintenance or replacement will the thermometer need over time?

Recalibrate periodically with a reference bath; if the polycarbonate lens cracks or the stainless housing corrodes, replace the entire unit.

What limit appears first when the thermometer is used continuously near its upper range?

Sustained exposure near 125 °F can accelerate lens clouding and housing stress, so monitor readability and plan replacement if drift exceeds 1 °F.
