The H25-IR PRO 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.

• Advanced Leak Quantification (ALQ™) technology eliminates the need for periodic adjustments to a calibrated reference leak source.
• Numeric Leak Rate Display
• Utilizes infrared technology to quickly and accurately pinpoint leaks as well as to extend sensor life and minimize false alarms.
• Excellent background gas rejection
• Automatic calculation of gas concentration regardless of flow rate
• "Search" and "Measure" mode
• Responds to leaks in less than 1 second and detects leaks as small as 0.03 oz/yr (0.9 g/yr)
• Improved menu system and navigation
• Assortment of probes available for specific applications
• Comprehensive diagnostics keep track of system parameters
• CE / EN50270:2006 / EN55011:2009 / EN61010-1 IEC61010-1 / UL61010-1:2001 / CSA 61010-1
