## Description

Review: Very handy for heatpump debugging - Very useful gauge, hardly use manifolds anymore whilst debugging heatpump.
Review: Love it - Once I paired it the first time, then turned it off, then on, it wouldn't pair the second time, so you have to swipe away the app, then relaunch it and it works. 3 'blinks' and it pairs, every time, no problems. The distance you can take your phone away before losing connection isn't great, but I still love this thing, best gas gadget for me. I do upto 8 tightness tests a day.

## Questions & Answers

**Q: 115i differential temperature. answer confusing?? "has been added" - "you do have to calculate" do you mean "do not have to calculate? thanks.**
A: Deepest apologies, there has been a miscommunication, the app does the calculation for you. The app does all the calculations and does tell you what the difference is between the 2 temperature readings. Apologies for any confusion!

**Q: Can this be used to measure wooden floor surface temperature? Thanks.**
A: I would think so but don’t know for definite

**Q: what is the maximum pressure can do?can it measure 300bars?thanks**
A: On the assumption your question contains a typo (300 BAR ??? = 3,351 PSI !) I'll assume you meant 300mbar.
If this is the case, the answer is no, the device limit is +150mbar (+ve pressure) or -150mbar (vacuum) with a max (very short duration) overpressure rating of 500mbar.

**Q: can this be used to tell a pressure difference between two rooms, determining if there is a pressure differential?**
A: Yes it's a differential pressure meter with a measuring range of -150 to 150mbar and a resolution of 0.01 mbar

### ⭐⭐⭐⭐⭐ Very handy for heatpump debugging
*by P***R on 13 October 2025*

### ⭐⭐⭐⭐⭐ Love it
*by K***X on 6 August 2018*

### ⭐⭐⭐⭐ 450i anemometer: works fine
*by A***Y on 25 September 2021*

The 450i anemometer worked fine (screenshot attached). I did the math using the cross-section area of the duct, and the number was within 5% of than the rated output of the blower that I was to create the air flow. The app was easy to install, but asked access to my contacts and location. The manufacturer should offer options to disable this, and should not bundle reviews for all smart probes into one. Please offer the case with foam inserts to keep the probes. Thanks!
