- The Nova 339 Methane Leak Detector has been designed for measuring the percent methane, natural gas or propane gas in air. A sensitive but rugged infrared detector measures the methane or propane in air and displays the actual percentage by volume on a digital display. This is an ideal method of measurement for leak detection because the sensor will not burn out or become 'blinded' as do some catalytic types.
- The Model 339 had rechargeable battery operation and has no warm-up wait. A built-in sample pump, hose, probe and flow indicator are also provided. Built-in audible and visual alarms are included. The alarm set point is field-adjustable. LED lights tell when to recharge and verify recharging. The recharger is included.

- Digital meter readout with backlight
- Cannot be 'blinded' by high concentrations
- Rechargeable battery operated
