Everything you need for fast, reliable, professional leakage protection. This unit detects all common refrigerants, such as CFC, HFC, HCFC and H2 so you will be able to detect even the smallest of leaks.
Leaks on a refrigeration system or heat pump have serious consequences. A leaking system no longer provides its required cooling capacity, and, in the worst case scenario, system components can be damaged, not to mention the environmental damage and costs incurred by your customer. You need fast, reliable measuring instruments in order to be able to detect even the smallest of leaks.
Features
- Extremely high sensitivity of 3g/a enables detection of even the smallest leaks
- Visual and acoustic alarm for optimum leakage detection
- Permanent sensor check, ensuring that your work is both safe and fast
- Earplug connection for safe leakage detection in loud environments
- Fast, reliable leak detector for all common refrigerants
- Sensor is permanently monitored, and displays malfunctions or contaminations on the screen
- Use of test leaks is therefore no longer necessary
- If dirty, the sensor can be easily cleaned, and is then ready for use again straight away
- Flexible gooseneck
- Drag pointer function indicates maximum leakages, making it easier to locate leaks
- If a leak is found, the display changes from green to red
- Audible signal also indicates that a leak has been detected
