If you like to keep things simple, we recommend the testo
316-1 gas leak detector: Identifying and locating leaks or
even reading off concentration values in ppm or %LEL
(lower explosive limits) are all exceptionally easy. No
training required thanks to the intuitive traffic-light scale on
the head and the display illumination.

Key benefits:
1. Multi-colour LED (visual and acoustic alarm)
2. Sensor self-test and automatic zeroing
3. Flexible probe for locations that are difficult to access
4. Display with intuitive traffic light backlighting
5. Battery-powered
