634 Pro Surveyor
The 634 Pro Surveyor is a professional-grade dual-sensor portable gas leak detector designed for natural gas pipeline surveys and utility leak detection. It detects both methane and hydrogen across a wide range of 1 ppm to 1% gas (10,000 ppm) with an LED bar meter display. The instrument requires no field calibration, making it ideal for utility crews performing routine leak surveys.
