AZ7201
AZ7201
Selective CH₄/propane leak detector with flexible probe, semiconductor sensor, built-in gas filter. Not explosion-proof.
Reference price: USD 126.00
Frequently Asked Questions
Why does the gas detector require a longer warm-up time after long-term storage?
After long-term storage, the semiconductor sensor needs extra stabilization time. Restarting the detector several times after automatic shutdown helps achieve sufficient warm-up for stable detection.
Is the AZ7201 less sensitive than other gas leak detectors?
No. The AZ7201 is optimized for selectivity rather than broad sensitivity. It focuses on stable detection of methane and propane while minimizing false responses from unrelated gases.
Can the AZ 7201 be used in explosive atmospheres?
No. This product is not explosion-proof certified and must not be used in hazardous or explosive atmospheres with high gas concentrations.
What gases does it detect?
Methane (CH₄, natural gas) and Propane (C₃H₈, LPG).
What is the flexible probe length?
Methane (CH₄, natural gas) and Propane (C₃H₈, LPG).
What is the sensitivity for each gas?
Methane: 1200 ppm. Propane: 40 ppm.
What is the response time?
Within 10 seconds.
What is the warm-up time?
Within 60 seconds.
