Features of ZMJ80XD Series Density Monitors

Using gas compensation, higher set point accuracy
Class 1.0 display for full scale
Suitable for indoor or outdoor installation
Micro switch, can switch freely between normally open and normally closed points
Up to four pairs of nodes, multiple options such as double alarms and double locks can be realized, making monitoring more secure and reliable
High shock resistance
No need to fill oil, no oil leakage hazard
Normally closed contacts will not falsely alarm due to vibration
