The Bacharach H25-IR PRO Industrial Refrigerant Leak Detector is capable of detecting over 40 of the most commonly used refrigerants and halogen gas compounds as well as R600a and R290. It can be used to locate and then quantify gas leaks, as well as log and totalize a group of leaks in a system. The H25-IR PRO adds new ground breaking capabilities, including proprietary leak quantification technology, that ensure accurate and reliable operation.

The H25-IR PRO raises the industry benchmark for high-production gas detection and analysis. In addition, a new menu system simplifies setup and operation while preserving the preferred digital numeric leak rate display. For users who are required to validate instruments against a known reference leak source, an optional leak reference tool, the LS-25 Series Leak Standard, is also available.
