115i Clamp Meter - Amp Clamp for Heating & Cooling Systems - HVAC Thermometer for in-Pipe Measurements & -58° to 302 °F Measurement Range - HVAC Temperature Probe with Bluetooth & App Operation

i absolutely love this clamp meter! it works every time and i have had these for years!

Great very accurate to get reading for super heat & subcooling easy to use

When used with the other smart probes (pressure manifold, thermohygrometers, other temperature clamps and the Testo app) it makes HVAC work a breeze. I can keep an eye on every part of the system on my tablet, perform several different tests and get all sorts of measurements with a push of button. The accuracy of the probes is amazing. Lost the back battery plate on one of my clamps but I'm pretty sure that's more my fault than Testo's

Im a refrigeration technician. I use temperature clamps to get superheat and subcool readings on many different kinds of equipment. I bought these to replace the wired temp clamps on my testo 550s digital gauges because unfortunately they broke in under a year. Hopefully these will be different. The part that broke on the wired ones was the connection to the gauges. Overall i like these theyre accurate to each other and are fairly quick to adjust compared to Hilmors temperature clamps that I tested side by side. Will try to update if anything bad happens with them.

These are so awesome. I had the corded ones for several years and had to put new ends on because they would break. These have fairly good range. If I am inside a building, I may have to put my phone by a window to get the signal. I'd say I was able to go 30 ft. If I just want a temp of a pipe, I can do that and open the app to get the temp off my phone.

I love them

I've used these for about a month now. I bought two, one for each A/C line and sometimes One for the INSIDE and One OUTSIDE readings without having to back and forth in the house. 1. Bluetooth setup is AUTOMATIC / EASY! 2. Bluetooth RANGE, I have a 1 story ranch, A/C on one END and I can still receive signal at the other end of house, 3. BATTERY life, is extreme. After 8 hours a day usage for a Month the 1.5V AAA Batteries were only down to 1.49V. 4. App is easy to use and setup plus a lot of extra features. 5. QUALITY, Top Quality! As always, hope this helped at least one person. Vegas OBie
