Features:

The MD-S275 is an intelligent, wireless, and outdoor-grade digital pressure gauge powered by a lithium battery. Featuring an IP67 protection rating, it is designed for long-term deployment on outdoor pressure pipelines. Its lithium battery power source, combined with a low-power design, ensures a normal operating lifespan of 2 to 3 years. Furthermore, the device supports a range of mainstream wireless communication protocols, including 4G, NB-IoT, LoRa, and LoRaWAN. Parameters can be configured-and firmware updated-either locally via a dedicated Bluetooth app or remotely via the "DaLanMao" platform, thereby simplifying the work for installation and maintenance personnel. Finally, the device employs a dual-mode data transmission strategy-sending routine data at scheduled intervals while immediately transmitting alarm data-to ensure the utmost timeliness in alerting.
