## Questions & Answers

**Q: Can you use it to measure air mass? Like kg / hour? And does it compensate for air temperature and air pressure?**
A: It measures air velocity, period. Does not compensate for pressure or temperature. Does not measure air mass flow directly.

**Q: Can it calculate or convert to Feet per minute?**
A: Here are the specs you are looking for:

Measuring range: 0 to 6,000 fpm
Accuracy: ±(20 fpm +5 % of m.v.) (0 to 394 fpm) / ±(59 fpm +5 % of m.v.) (394 to +3,000 fpm)
Resolution: 1.97 fpm
Volume flow: (cfm) 0 to 99,999 cfm (Resolution: 0.1 cfm)

**Q: Can you use it to measure the delta?**
A: There's a trendline function that can keep track of changing temp over time.

**Q: Does this device show a live CFM reading?**
A: Why yes it does sir

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

Very useful gauge, hardly use manifolds anymore whilst debugging heatpump.

### ⭐⭐⭐⭐⭐ Excellent bluetooth current clamps
*by B***Y on 21 January 2026*

Excellent bluetooth current clamps. Robust and pretty accurate Recommended

### ⭐⭐⭐⭐ 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!
