Data sheet testo 317-2 / testo 316-1 / testo 316-2 / testo gas detector / testo 316-EX Gas leak detectors For a quick overview testo testo testo testo testo Fast testing Over and over again, devastating explosions and fires are Thanks to technological developments, it is today possible caused by leaky gas pipelines. However, even smaller leaks to use a test instrument to carry out a gas pipeline test (leak in the gas pipelines, some of which cannot be detected by quantity test) in a very short time. If a leak is determined, odour, lead directly to higher consumption and, in the long the site of the gas leak can be identified very quickly and run, increase the risk of accidents. reliably with the help of the gas leak detector. How do leaks occur? Leaks can be caused, for example, by hairline cracks (cracks which are hardly identifiable with the naked eye) in the pipelines. The often used hemp sealant can also, after many years of use, become leaky.

Overview Testo gas leak detectors Measuring instrument The convenient gas leak detector for beginners The detector for leaks in natural gas pipes The gas leak detector with integrated pump for fast check measurements Gas detector with EX-protection Measuring range Methane Lower response thresholds 8 segment trend display Battery life Other features Earphone socket • extendable probe • Inherently safe sensor according to Protection class IP54 EU guideline 94/9/EG (ATEX) 2004/108/EG

testo 317-2 testo 317-2 gas leak detector including case with belt clip and wrist strap and batteries Highly practical gas leak detector for fast checks on gas pipe connections, with visual bar display. • Optical bar display • Sensor self-test after switching on • Rising alarm tone with increasing gas concentration • Continuous tone when alarm threshold is exceeded • Audible confirmation of readiness to operate • Battery monitoring with optical display Sensor types

The detector for leaks in natural gas pipes testo 316-1 testo 316-1 electronic gas leak detector with flexible probe and battery The testo 316-1 gas leak detector quickly detects even the smallest leaks. • Flexible measurement probe for inaccessible pipes • TopSafe case protects from dirt and impact (optional) • Audible alarm if limit value is exceeded • Optical alarm Sensor types Accessories for measuring instrument testo 316-1 testo 316-1 TopSafe; protection case, incl. stand, protects from dirt and impact

The testo 316-2 is extremely user-friendly and ideally suited to fast check measurements thanks to its integrated pump, its optical presentation of the gas concentrations detected, and the integrated rechargeable battery. • Optical and audible alarm with bar display for increasing and dangerous gas concentrations • Trend display shows maximum leakage • Integrated pump • Flexible measurement probe for inaccessible places • Earphone connection for secure leakage localization in loud surroundings • High duration of use thanks to rechargeable battery General technical data

Be sure. Gas detector Part no. 0632 0323 Testo‘s gas detector is a multi-range gas detector for the gas types methane, propane and hydrogen. Gas concentrations are measured by the semi-conductor sensor in the ppm range and are shown in the display with a resolution of 1 ppm. • Audible signals if approaching lower explosion limit • Continuous tone and warning in display if explosion limit is reached • Flexible probe extension for difficult-to-access points Sensor types

Gas detector with EX-protection Part no. 0632 0336 Proof of gas and leakage localization on gas pipes and installations in indoor and outdoor areas The testo 316-EX, which conforms to the guideline 94/9/ EG (ATEX), is a multi-range gas detector with Ex protection for the gases methane, propane and hydrogen. The gas concentrations are measured by the semi-conductor sensor in the ppm range and are shown in the display with a resolution of 1ppm. • Flexible measurement probe for inaccessible pipes • 1 ppm resolution on display • Indicator suppression for comfortable locating of the leak • 94/9/EG...
