Industrial Refrigerant Leak Detector
Bacharach’s H25-IR PRO is a next generation industrial-grade refrigerant leak detector and gas analyzer capable of
detecting over 40 of the most commonly used refrigerants and halogen gas compounds as well as R600a, R290 and
R744 (CO2). 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.
Features & Benefits
- Advanced Leak Quantification (ALQ™) technology eliminates the need for
periodic adjustments to a calibrated reference leak source.
- Utilizes infrared technology to quickly and accurately pinpoint leaks as well
as to extend sensor life life and minimize false alarms.
- Automatic calculation of gas concentration regardless of flow rate
- Responds to leaks in less than 1 second and detects leaks as small as 0.03 oz/yr (0.9 g/yr)
- Assortment of probes available for specific applications
- Comprehensive diagnostics keep track of system parameters

H25-IR PRO Probe Options
||Features an LCD display to show the current leak rate as well as an LED feedback indicator to signal the leak rate
frequency or a defined threshold. Most of the instrument’s primary functions, setups and features can be accessed via the probe’s keypad.
||Features a button that can zero the unit or switch between the instrument’s search and measure modes. The indicator LED provides visual feedback of the leak rate frequency or a defined threshold.
||Features flexible hose which enables basic pinpoint leak detection but does not provide any visual feedback or allow any user input via the probe.
LS-25 Leak Standard
||The LS-25 Series Leak Standard provides an NIST-traceable reference leak source for instrument functional testing or adjustment. The unit is factory calibrated and shipped fully charged with the selected refrigerant, sufficient to provide years of service. Annual re-calibration is suggested.
