It measures differential temperatures (T1, T2, and T1-T2) with a wide range from -58°F to 572°F, displayed on a large backlit screen for easy reading in any environment. Designed for HVAC pros and managers who demand precision and portability, it fits comfortably in your pocket while delivering quick, reliable readings. ## Description The UEi PDT655 provides you with all the benefits from the PDT650 but with a bigger display, bigger buttons, magnets for ducts all in the same compact size to still fit into your pocket! Functions Temperature Range: -58 to 572°F (-50 to 300°C) Temperature Differential - T1, T2, T1-T2 Features Back-fold temperature probe Reads open or closed Min/Max Back light Large easy-to-read display°F or °C Auto power off Built-in magnet Low battery indication 1-Year limited warranty Includes Battery (CR2032) User Manual Review: The device is somewhat on the larger size, but for most users this is a plus. Its length is 6 inches and the width is 1.5 and it about ¾ inch thick. It will fit in a pocket but there will be no hiding it there, too long for that. However, it’s actually about ½ inch shorter that the Samsung phone I carry. The readout numbers are ¾ high and easy to read from 10ft away with good lighting. The display does light up, but only for about 4 seconds, just long enough to see the number if you’re in a dark basement or attic. The probe length is 5 inches and has enough mechanical resistance that it holds the position as you place it into a vent or hole. I was able to hang it onto a vertical return grill by the probe only, since in this case the grill was aluminum. The built-in magnets will hold it nicely on a flat metal area but probably not on a round duct. On those you could easily hang it by the probe though. It uses 1 CR2032 battery which helps keep the weight down. It’s a common enough battery that big box and drug stores sell them and they are cheap. It will self-power off after one hour, a nice feature, but it also means that any readings you have also disappear. It updates very quickly and follows the temp rise in a duct very near real time. It followed the rise I saw with my Fluke thermocouple and I was impressed with that. Accuracy seems reasonable and matches up nicely with other thermometers that I believe to be accurate. See photo Review: Used by pros for a reason. Easy to ready. Very handy. ## Features - DIFFERENTIAL TEMPERATURE: PDT655 can store temperature readings and measure differential temperature by Measuring (T1 - T2) - VERSATILE: The PDT655 fits in your pocket and can take readings in tight spaces with a folding probe. - EASY-TO-READ: The PDT655 comes equipped with a large digital display for easy reading.
