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. Sniffing leaks at less than 0.03 oz/year, the DR58 detects all HFC, CFC, HCFC, HFO and blended refrigerants with superior sensitivity at detecting R-410A 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. The DR58 boasts an 18 hr 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.
