Bacharach H25-IR PRO Refrigerant Leak Analyzer

Industrial NDIR gas leak analyzer with Advanced Leak Quantification (ALQ™) for detecting and quantifying 40+ refrigerants (plus dedicated R-290 / R-600a / CO₂ / SF₆ models), 4–20 mA output, and four relays.

Key advantages

0.03 oz/yr class sensitivity — standard/SF₆ models 0.03…3.49 oz/yr (1…99 g/yr); response <1 s typical.
ALQ™ — quantifies leaks without a calibrated reference leak source.
Probe options — 6 ft / 12 ft; basic to smart probe mirroring the UI.
Plant I/O — 4–20 mA + four relays; 100–240 Vac; 2-year warranty.

Typical applications

Industrial refrigeration and chiller rooms needing quantified leak rates.
HVACR maintenance for CFC/HFC/HCFC blends and specialty gases with dedicated models.
Fixed-bench leak analysis with relay/analog signaling.

Selection guide

Gas model — Standard halogen blend list; dedicated R-290, R-600a, R-744 (CO₂), SF₆ configurations.
Range — Standard/SF₆: 0.03…3.49 oz/yr; HC models: 0.11…3.49 oz/yr; CO₂: 5…500 ppm above ambient.
Environment — 0…50 °C; 5…90% RH non-condensing.
Power — 100…240 Vac, 50/60 Hz.
Size / weight — 15.5 × 10.8 × 4.0 in.; 18 lb (8.2 kg).
Warm-up — ~1 minute.
Approvals — CE; UL/CSA/IEC/EN 61010-1.

Common mistakes

Ordering the standard halogen model for CO₂/SF₆/HC-only duty without the dedicated sensor configuration.
Undersizing probe length for large equipment rooms.
Treating it as a pocket sniffer — it is an industrial analyzer with plant I/O.
Test & measurement

When to RFQ / what to tell us

Target refrigerants / gas model (standard, R-290, R-600a, CO₂, SF₆).
Probe length and smart vs standard probe.

FAQ

Q: Does one unit cover CO₂ and HFCs? A: Dedicated models exist for CO₂, SF₆, R-290, and R-600a. State gases in the RFQ.

Q: What should I send for a quote? A: Gas model, probe, I/O needs, quantity. Compatible with systems using Bacharach H25-IR PRO if you need a drop-in check — we do not claim authorized-dealer status.
