Portable infrared leak detector with ppm readout, for SF6, refrigerants and ammonia
The D-TEK Stratus combines in a single hand-held unit the hunting of the gas cloud and the exact pinpointing of the leak: the display shows the concentration in ppm to narrow down the area and, in pinpoint mode, the detector marks the escape precisely.
Advantages
Two detectors in one
The cloud-hunting mode with ppm readout outlines the area of highest concentration and the classic pinpoint mode identifies the exact spot: two ways of working with the same instrument.
Long-life infrared sensor
The redesigned infrared sensor lasts up to 2,000 hours, is replaced in the field in seconds and its sensitivity does not degrade over time.
SF6 and dozens of other gases
The standard refrigerant sensor detects SF6, ammonia and the CFC, HCFC, HFC and HFO refrigerants, including A2L blends; the optional sensors add CO2 and flammable refrigerants.
Certified sensitivity
Tested to the EN 14624:2020 standard, with sensitivities from 0.5 to 5 g/yr depending on the gas (1 g/yr for R134a) and A2L and CE certification.
Battery for the whole shift
The rechargeable lithium-ion battery delivers 8 to 10 hours depending on the mode, is field-replaceable and quick-charging; the unit even operates while charging via USB-C.
Applications
- Locating SF6 leaks in circuit breakers, GIS cubicles and substation switchgear.
- Maintenance of industrial air conditioning and refrigeration, including A2L refrigerants.
- Inspection of ammonia and CO2 installations with the corresponding sensors.
- Periodic verification of the detector itself with calibrated reference leaks.
About the product
Weighing 590 g with a 43 cm flexible probe, the unit is handled with one hand; the large LCD display shows the concentration, the recorded maximum and the battery status, and the automatic and manual zero modes adapt the response to the surroundings. The kit comes in a rugged carrying case with the infrared sensor, lithium-ion battery, spare filters, AC wall charger with USB-C cable, extra-long probe and earbuds.
The detector is not ATEX certified, so local requirements should be checked before working in classified areas. Available accessories: CO2 and flammable refrigerant sensors, 69 cm extra-long probe, needle probe extension, calibrated reference leaks, spare battery and charging cradle.

Frequently asked questions
Does it detect SF6 with the standard sensor?
Yes. The included refrigerant sensor detects SF6 as well as ammonia and the CFC, HCFC, HFC and HFO families.
What is the ppm readout for?
For hunting the gas cloud: the indicated concentration guides you towards the leak area before switching to precise pinpoint mode.
How often is the sensor replaced?
The infrared sensor lasts up to 2,000 hours of use and is replaced in the field without tools.
Can it be used in explosive atmospheres?
It is not ATEX certified; local requirements must be checked before working in classified areas.
How can correct operation be verified?
With the calibrated reference leaks available as accessories, which emit a known gas flow for more than two years.
