Leaks in your refrigeration system or heat pump can have serious consequences. The system becomes inefficient and, in the worst case, components can be damaged. Not to mention the negative environmental impact and the additional costs you incur as a result of this damage. That is why you need fast, reliable measuring instruments such as the testo 316-4 set 1 refrigerant gas leak detector to detect even the smallest leaks.
Provide cover: Testo 316-4 Refrigeration gas leak detector, case, power supply and earphones.
Advantages of refrigerant gas leak detector testo 316-4 set 1
- The most comprehensive gas leak detector: testo 316-4 set 1 is a fast, reliable leak detector for all of today's most common refrigerants
- The sensor is constantly monitored, tested and displayed if there are any problems or contamination right on the screen. If it becomes dirty, the sensor can be easily cleaned and is ready for immediate use again.
- Gooseneck probe makes it easy to measure in hard-to-reach areas
- Extremely high sensitivity ˂3g/a according to EN 14624 allows detection of even the smallest gas leaks
- The leak level display allows you to pinpoint exactly where the gas leak is occurring.
- The light and buzzer warning function is extremely useful: the display light will change from green to red and the buzzer will also sound if the device detects a leak. The headphones included in the device set help you to easily hear the warning in noisy environments.
- Further options for ammonia (NH3): for refrigeration systems operating on ammonia, you can upgrade the testo 316-4 set 1 with a spare measuring head for ammonia (NH3). Or you can buy a dedicated gas leak detector for ammonia (NH3) such as testo 316-4 set 2
