The first acoustic camera with TDLAS technology for Nature gas leak detection and concentration measurement

How does the HA3LX detect methane leaks compared to standard acoustic cameras?

A: Unlike standard acoustic cameras that only detect the sound of leaks, the HA3LX integrates a TDLAS laser sensor. This allows it to verify if the leaking gas is methane and precisely measure its concentration (0 to 50,000 ppm*m) in real-time, providing a dual-verification system.

Is the HERTZINNO HA3LX safe for use in explosive environments?

Yes, the HA3LX is fully ATEX certified (Ex ib IIC T4 Gb), making it intrinsically safe for use in Zone 1 and Zone 2 hazardous areas typically found in oil & gas and chemical industries.

What is the maximum detection distance of the HA3LX?

The HA3LX has an acoustic detection range of up to 200 meters for locating sound sources (like leaks or discharge),for drone detecting up to 1.5km and a laser methane detection range of up to 30 meters.
