339K便携式甲烷泄漏检测器，手提箱（K）外壳
The Nova 339 Methane Leak Detector has been designed for measureing 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.

470D2甲烷连续过程分析仪，红外探测器 - 470系列
The Nova 470 Series CH4 analyzers utilize a simple and reliable microprocessor-based non-dispersive infrared detector specific to CH4. The detector pulses an infrared beam of light through the sample tube, without the need for a mechanical chopper. In operation, the internal sample pump draws the sample gas through the filter/condensate trap, secondary filter, flowmeter, and then on to the infrared detector. The detector output is digitally linearized and then displayed as percent or PPM CH4 on the digital meter. The output is also available as an analog or digital signal.
