Kundo xT exchange sensor easy DIY exchange every four years

Easily and inexpensively meet the legally prescribed requirement to maintain the carbon dioxide detector according to the manufacturer's instructions. 

Kundo XT overhauls, calibrates and guarantees, among other things, the Sensor and supplies it for a pleasant price as an "exchange sensor" for simple replacement. This prevents expensive on-site calibration and your company is unprotected for just a few seconds. 

The revision devices are also advantageous for defective carbon dioxide CO2 products. 

How to determine which device is defective: 

The sensor is defective if you first get a green light after initialization and yellow after +/- 3 minutes (operating failure) 

The alarm unit is defective if it becomes very hot or if you receive constantly changing status messages after initializing.
