SF6 gas density controller ZMJ1-Y

Introduction
Used to monitor the density of insulating gases such as SF6 inside containers. Supports LoRa wireless communication with long transmission range and low power consumption. The product incorporates intelligent temperature compensation to track nonlinear pressure variations of SF6 and other insulating gases in real time, enabling accurate measurements. A built-in high-capacity lithium primary battery removes the need for external power cabling, simplifying deployment for online monitoring of high-voltage systems. Suitable for density detection of insulating gases in high-voltage switchgear and for solutions in new substations or retrofitting existing substations.
