HVAC differential pocket thermometer
The UEi PDT655 is a folding digital thermometer built for HVAC/R technicians who need fast differential readings on the job. It stores two measurements and calculates the difference between T1 and T2 directly on the device. A 5-inch folding probe reaches into ducts, vents and tight equipment spaces while the main unit stays in hand. The instrument is supplied new and ready for field use.
Fits in a tool pouch and mounts on metal ductwork
When folded the body measures 6 by 1.5 by 0.75 inches, so it slides into a pocket or service bag without snagging. The built-in magnet holds the meter against steel panels, freeing both hands for probe placement or manifold work. A backlit display stays readable in dark mechanical rooms and the large buttons operate easily with gloves on. No external power pack or special mount is required.
One-second refresh across a wide temperature range
The probe updates every second from minus 58 to 572 degrees Fahrenheit (minus 50 to 300 degrees Celsius), covering refrigerant lines, combustion air and hot water systems alike. Min and Max capture lets you log extremes during a cycle and a low-battery indicator warns before the display dims. The unit draws minimal current from its internal cell, so a single battery lasts through extended service calls.

Questions about this item
How long will the battery last during continuous daily use?
The display includes a low-battery indicator so you can replace the cell before it dies during a job.
Does the thermometer get hot or make noise when left on all day?
The PDT655 has no moving parts and draws minimal power, so it stays cool and silent during extended use.
What extra equipment is needed to measure differential temperature?
The folding probe handles both T1 and T2 readings, so no additional sensors are required.
