Product Description:
The MD-S273 wireless digital pressure gauge is a low-power wireless transmission digital pressure gauge independently developed by Shanghai Meokon. It uses battery power. This series of wireless digital pressure gauges has a variety of wireless transmission methods, including NB-iot/4G.
This series of products adopts explosion-proof alloy aluminum housing and 304 stainless steel connector, built-in high-precision pressure sensor, equipped with LCD full liquid crystal display, can measure gas, liquid, oil and other non-corrosive media to stainless steel, and has the characteristics of strong media compatibility.
This series of products has a Bluetooth configuration function, and the sensor collection speed, sending frequency, high and low voltage alarm, and fluctuation alarm values can be set.
MD-S273-4G is a wireless digital pressure gauge with 4G transmission. With China Mobile's mature 4G network, it uploads the on-site pipeline pressure to the cloud. Users can match the IP address and other conventional parameters on-site or remotely.
MD-S273-NB is a wireless digital pressure gauge with NB-iot transmission for three Netcoms. It adopts NB-iot technology, which has the advantages of low power consumption, high transmission efficiency, and low tariff.
