Fieldpiece - DR58 Heated Diode Refrigerant Leak Detector - Ultra-Sensitive Leak Sniffer with Large, Backlite LCD Screen - Lightweight HVAC Tool

Finally bought my first refrigerant leak detector as a HVAC technician after getting tired of trying to use the dye and uv light method. I am very happy with my new leak detector. Sniffing leaks at less than 0.03 oz/yr (, the DR58 detects all HFC, CFC, HCFC, HFO and blended refrigerants with superior sensitivity at detecting R410A . This refrigerant leak detector is also compatible with the new A2l refrigerants being released this year. Very happy with my purchase!

Fieldpiece make a high quality leak detector. Very sensitive. I am very impressed.

I work as a techn. in the phx area so far only had about 3 weeks have found 99 % accuracy for leak on indoor evap coil fin pack area R410a,other leak detectors seems to not work as well for this refrigerant wil be useing for R404a,R134a,R22,407c mostly hope it works as well had basic inficon housing cracked at battery cover worked ok for about a year then could not find anything,had yellow jacket hot tip work very well for about 10 years but went to change tip and all wire came out, too expensive i think but did work very well, happy so far with fieldpiece performance and price,have other products, meters,clamp on all work well

Great sensor except one flaw… if tip of probe is farted into directly, will completely destroy sensor. Sensor replacement is not readily available anywhere close by so keep this in mind and keep the sensor away from your lower half after a night of miller lites and corned beef/sourkraut on rye bread.

Work well for finding general vicinity of leak but not great at pinpointing. Still need big blue to locate. Does save time i guess

Works great much better than my Tif more accurate and quicker.

Very good detector ?!

We have a few other leak detectors in our automotive shop and this is the most accurate one we have used.
