DR58 – Heated Diode Refrigerant Leak Detector

Sensitive. Portable. Durable.

Where to Buy

  • Sensitivity better than 0.03 oz/yr (1g/a)
  • Bright, LCD screen with easy-to-see bar graphs and numeric readings
  • 18-hour USB rechargeable lithium-ion battery
  • Detects all HFC, CFC, HCFC, HFO and blends
  • Flashing lighted tip, multiple alarms, and numerical leak size indicator
  • Manual or automatic zeroing

One-of-a-kind by design.
Since it’s a Fieldpiece, the DR58 Heated Diode Refrigerant Leak Detector is full of the features you need. It’s also designed to handle the abuse that most leak detectors can’t with an impact resistant IP54-certified body that fits easily in your hand.

Clearly see even the smallest leak.
Sniffing leaks at less than 0.03 oz/yr (1g/a), the DR58 detects all HFC, CFC, HCFC, HFO and blended refrigerants with superior sensitivity at detecting R410A refrigerant. On the DR58’s new, bright backlit LCD screen you’ll see easy-to-read bar graphs, numeric readings and customizable dual alarms. No more guessing about what’s leaking. Also, it can both automatically and manually zero to refrigerant gas concentrations giving you total control.

Detects faster. Lasts longer.
The DR58 boasts an 18-hour battery life that’ll last longer than you will on the job site. Yes, it’s built to perform. Soap bubble solutions can take several minutes to form visible bubbles and messy UV dyes can take several hours to travel through a running system.

Every feature you’ll love:

  • Ruggedized and IP54-certified body
  • Compact to fit in your hand
  • Bright, backlit LCD screen shows bar graph and numeric readings
  • Heated diode sensor 300 hour life, typical
  • Dual audible and visual alarms – turn the beep on or off when you want
  • LED lighted tip and loud beep help find leaks in noisy and dark environments
  • 18-hour USB rechargeable battery – work all day and all night on one charge
  • Numerical Leak Size Indicator with Bar Graph
  • Non-conductive, sturdy probe stays where you want it
  • Weighs less than a pound
  • Full control – Automatic Zero, Manual Zero and Mute functions
  • Works on A2L Refrigerants

  • What is the difference between the DR58 and DR82?

      1. The DR58 uses a heated diode sensor. The heated diode’s advantage is that it detects absolute concentration levels so it can be held on a leak and will continue to beep. It is also initially very sensitive. Its major disadvantages are that the sensor becomes less sensitive over life, eventually needing replacement and it is more sensitive to some refrigerants than others.
      2. The DR82 uses an infrared (IR) sensor. It detects a CHANGE in concentration, so the wand must keep moving. The main advantages of the Fieldpiece IR sensor are that its sensitivity will remain the same over the life of the instrument, the sensor will last the lifetime of the instrument, it will not trigger on humidity or on oil, and it has nearly the same sensitivity to most refrigerants. The main disadvantage of infrared sensors is their sensitivity to mechanical disturbances.
  • Why won’t it stay on / why won’t it charge?

    • If no sensor is installed or the installed sensor is broken when the unit is turned on an alarm will sound and the unit will turn off.

  • How long does the sensor last?

    • If it seems like your leak detector is no longer picking up leaks or is not as sensitive as it was when you first bought it, try replacing the filter. This should fix the issue. If this does not fix the issue try replacing the sensor

  • How do I order a new sensor?

      1. Contact your local Fieldpiece supplier and have them order part number “RHD1”
      2. Carefully insert the new sensor and replace snoot. The sensor can be inserted in two different configurations, either of which will allow the DR58 to function correctly.
  • Where is the sensor located?

    • To install or replace the sensor, make sure the unit is turned off. Then, unscrew the snoot on the DR58 and if replacing gently pull the sensor from the base.
