Aisko Explosive gas meter - AZI-VZ7291

Measuring device for explosive gases - AZI-VZ7291 The measuring device model VZ 7291 is a highly sensitive device for checking leaks in gas appliances.gas appliances, for detecting and identifying damage to gas appliances and equipment, for checking the tightness of liquid gas cylinders, etc. The simple operation enables fast and accurate leak detection. The flexible 450 mm long probe allows easy access to hard-to-reach places. The device has an acoustic signal and a visual six-step scale with leak detection diode. If the situation requires a silent test or the ambient noise is so loud that the acoustic signal may be difficult to hear, the test can be carried out with headphones. The meter can be powered by four 1.5 V AA alkaline batteries or by a 9 VDC/230 VAC power supply Hand-held meter in various technical services. in 2006 10. February According to the regulation (on detailed requirements for stations carrying out technical inspections of vehicles), this type of device should be part of the equipment of every vehicle inspection station.
