For easy and quick verification of switching points of density monitors
The (EU) F-gas regulation 2024/573 stipulates regular verification of density monitors integrated in switchgear. The DensiCheck can be used to quickly determine whether the switching points of density monitors trigger on time.
The B178R91 allows a quick, easy and precise verification of the switching points. Both density and pressure-based, mechanical and electronic measuring systems can be tested. 
The type of density monitor to be tested is connected to the hose, equipped with a quick coupling, depending on the connection. 
The test pressures are approached with the easy-to-operate hand pump, allowing the switching points to be tested quickly and easily. The switching point can also be approached very precisely with a fine control valve.
