Bacharach H25-IR PRO

The Bacharach H25-IR PRO is designed for organisations that require more than a simple go/no-go leak detector. Its high-resolution NDIR infrared sensor provides precise, stable and selective gas measurement, supporting detection of over 40 commonly used CFC, HFC and HCFC refrigerants. Dedicated models cover R-290 (propane), R-600a (isobutane), R-744 (CO2) and SF6, enabling standardisation on a single analyser platform across chillers, refrigeration systems and specialist industrial equipment.

Very high sensitivity, with minimum detection limits down to 0.03 oz/yr (0.85–1 g/yr) for standard and SF6 models, supports early leak identification and helps reduce refrigerant consumption and associated environmental impact. A fast response of less than one second (probe-length dependent) allows rapid tracing of leak paths around complex pipework and components, improving productivity during surveys and service visits.

Patented Advanced Leak Quantification (ALQ™) technology differentiates the Bacharach H25-IR PRO from basic sniffers. ALQ™ provides quick, accurate leak-rate calculations without a dedicated reference leak source or routine adjustments, simplifying both deployment and ongoing operation. The instrument automatically calculates gas concentration or leak rate independent of flow rate, helping to maintain consistency between users and locations.

Dual operating modes support both rapid screening and detailed assessment. In “Search” mode the analyser focuses on fast leak localisation, while “Measurement” mode provides numeric leak-rate values on the digital display. Versatile units, including mass, volumetric and concentration formats (model dependent), support internal reporting and regulatory documentation. The ability to quantify individual leaks and summate a group of leaks provides system-level views of emissions, assisting with maintenance prioritisation and compliance planning.

The Bacharach H25-IR PRO is engineered for reliable operation in mechanical rooms and general industrial environments rather than controlled laboratories. A warm-up time of about 60 seconds reduces delays at the start of testing. Excellent suppression of interfering gases minimises false alarms, helps protect the sensor and supports consistent readings over time.

Automatic and manual background adjustment functions allow the analyser to compensate for changing ambient conditions, helping to maintain accuracy as temperature or baseline concentration shifts. The unit operates over a wide temperature and humidity range as specified in the technical data, making it suitable for diverse plant conditions.

A comprehensive probe range enables the Bacharach H25-IR PRO to be configured for different access requirements and working practices. The standard probe with flexible hose is suited to reaching congested areas around valves, joints and heat exchangers. The LED + Button probe adds a local control button for switching between search and measurement modes, along with visual leak indication for use in noisy or visually complex environments.

The smart probe extends this functionality further by mirroring the main instrument interface. Its integrated LCD, LEDs and keypad provide remote viewing and control when the main analyser is placed on a bench, cart or fixed mounting point, supporting safer and more ergonomic operation. Multiple probe lengths, typically 6 ft and 12 ft, help match the configuration to compact racks or large-scale plant installations.

Four integrated SPDT alarm relays allow the Bacharach H25-IR PRO to drive external alarms or interface with control circuits, while the 4–20 mA analogue output connects to data acquisition systems, building management systems or PLCs. Visual status indicators on the instrument and smart probe, together with audible alarms via speaker or headphones, help ensure leaks are recognised quickly in busy areas.

Built-in data logging and comprehensive diagnostic functions (model dependent), including automatic and manual diagnostic modes, support structured troubleshooting and record keeping. These capabilities assist with verification of system integrity over time, help prepare for audits and contribute to reduced unplanned downtime.

The Bacharach H25-IR PRO combines a rugged benchtop/portable form factor with a compact footprint, making it straightforward to deploy in plant rooms, workshops or on service carts. Universal 100–240 VAC, 50/60 Hz power input supports use across global facilities without specialised power arrangements. Safety approvals aligned with international standards, including CE and UL/CSA/IEC/EN 61010-1, underline its suitability for professional use.

The analyser is supplied with an initial probe and operating instructions, and a range of accessories — including replacement probes, filters, O-rings, probe tips and bench kits — supports long-term maintainability. A two-year warranty and manufacture in the United States to industrial quality standards contribute to a low total cost of ownership. By combining sensitive leak detection, quantitative measurement, logging and diagnostics on a single platform, the Bacharach H25-IR PRO helps organisations standardise leak management, reduce maintenance effort and protect critical cooling and process assets.
