The central test paper of 32000 indicators permits a sure and quick control of humidity level and the control of physical state of refrigerant fluid.

The liquid and humidity indicators are designed to be installed on refrigeration and air-conditioning systems for domestic and industrial use. It’s possible to use them with all the refrigerant fluids of group II (Art.9, point 2.2 of Directive 97/23/CE, with reference to Directive 67/548/CEE) and they are defined as “pressure Equipments”, as described in Directive 97/23/CE, Art.1, point 2.1.4, and Art.3, point 1.3. Group II includes all refrigerants classified as A1 in annex E of EN 378-1:2008 standard.
