Sentinel Frost Test Kit

Sentinel frost test kit
The Sentinel frost test kit is designed for use during both installation and maintenance of ground soure of air source heat pump systems using glycol-based heat transfer (thermal) fluid. After installation the test kit will allow you to confirm the level of antifreeze present in the thermal fluid. During routine service visits it is important to continue to monitor the condition of the antifreeze/thermal fluid for degradation.

Progressive degradation will occur after several years in the system and the fluid will eventually need replacing. The test kit allows you to determine exactly when the replacement is required.
