A series of the compact detectors testo 317 consists from: the detector of leak of combustion gas from flues of testo 317-1, the detector of leak of methane (CH4) and propane (C3H8) testo 317-2 and a gas analyzer of monoxide of carbon (FROM) testo 317-2.
testo 317-1 - the detector for definition of places of leak of combustion gases from vent pipes and gas flues.
The detector is equipped with a flexible probe and at detection of leaks gives optical and acoustic signals.
testo 317-2 - a portable signaling device of leak of methane and propane which has 2 levels of indication: 100 ppm and 1% about. CH4. Growth of concentration of CH4 is displayed in a graphic look on the built-in display and increases the frequency of a sound signal. The protective leather cover and a thong on a hand is included in the package of delivery of the device.
Besides application in gas economy for control of leak of combustible gases, the device is widely used on HUNDRED to detection of leaks from the gas-balloon equipment automobile, trucks and buses.
testo 317-3 - a portable gas analyzer for monitoring of concentration WITH in air (to 0,2% WITH) with optical and sound alarm signals. The protective cover, a thong and earphones is included in the package of the device of delivery.
testo 317-3 directly displays in a digital form concentration WITH on the display and has 2 randomly adjusted boundary values at achievement of which is distributed optical and sound signals.
