HXG 3P by Sensit - Portable Combustible Gas Leak Detector

The Sensit HXG 3P is a portable combustible gas leak detector designed for methane, propane, natural gas, and VOC leak detection across confined space monitoring, manhole entry, vessel testing, pipeline purging, and EPA Method 21 emissions testing. The backlit LCD simultaneously displays %LEL (percent lower explosive limit) and ppm concentration readings for accurate gas leak identification and analysis. Its flexible probe design and dual-mode display make it well-suited for utility, pipeline, and industrial hygiene applications requiring rapid, accurate combustible gas screening.

What is the Sensit HXG 3P used for?
It's a portable combustible gas leak detector that simultaneously displays %LEL and PPM, giving you both a safety read and a sensitive screening number at once. It's used for pipeline leak pinpointing, valve and fitting inspections, confined space leak checks, and EPA Method 21 VOC emissions testing in LDAR programs.
What gases does the HXG 3P detect?
Methane, propane, natural gas, and VOCs. The specific response depends on the sensor calibration and your method's definition of target compounds. If you're screening for a specific compound, confirm the calibration gas and sensor setup match your requirement before fieldwork.
HXG 3P vs. a multi-gas confined space monitor — which do I need?
Use the HXG 3P when the job is finding and quantifying a leak — its probe design and %LEL/PPM display are built for pinpointing. Use a multi-gas monitor when the job is continuous atmospheric monitoring for confined space entry (oxygen, toxics, combustibles). Don't substitute one for the other.
Can I use the HXG 3P for EPA Method 21 LDAR work?
Yes — it's rated for EPA Method 21 VOC emissions testing. Method 21 is procedure-heavy: confirm your LDAR program's instrument setup requirements, calibration documentation, and data capture format before mobilizing. The instrument is one piece; the method compliance is the other.
How does the tick feature help with leak pinpointing?
The tick rate increases as the probe approaches the leak source, giving you an audio cue without needing to watch the display. Use it to locate the strongest response point along fittings, valve stems, and flanges, then use the numeric display to document a stable reading per your procedure.
What's a common mistake that causes missed leaks?
Poor probe placement. Leaks escape at specific points — valve packing, threaded joints, flange faces — and the gas plume can be narrow. Use the gooseneck to get the probe tip close and sweep slowly enough for readings to stabilize. Moving too fast is the most common reason a real leak gets a clean pass.
What's included in the rental kit?
The kit includes the HXG 3P detector, probe tip casing, calibration adapter, wrist strap, spare alkaline batteries, and user manual. Calibration gas and site-specific documentation forms are not included — confirm your program's pre-use check requirements before dispatch.
What does it cost to rent the Sensit HXG 3P?
$100/day and $265/week. Pricing beyond two weeks is by quote. For LDAR campaigns, total cost scales with the number of components being surveyed and crew size — budget based on inspection scope, not just rental days.
