  • The Fieldpiece DR58
is an excellent choice for HVAC and refrigeration technicians seeking a sensitive, durable, and easy-to-use leak detector. It offers great value within the professional market and performs exceptionally well with systems using refrigerants such as R-410A.

  • Very effective leak detector
Excellent leak detector, though it does give a low level false positive when there are other odors present, such as dryer sheets or soap. Extremely sensitive, able to detect small leaks outdoors with a light wind. Highly recommend.

  • Very sensitive leak detector
Excellent product, this was the only thing that could find an ultra slow leak that not even the accutrak supersonic listener could detect, half the price too.

  • Good Deal
Good Deal, Would Do Again, Works great!

  • Excellent
Excellent, sensitive, very useful, and very well packed in plastic housing.

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

  • Very well made!
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! ... show more

  • DO NOT FART DIRECTLY INTO DETECTOR!!!
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. ... show more
