NHR-XTRM temperature remote monitoring instrument is a temperature physical quantity detection signal display control instrument, which can monitor multiple measurement signals in turn, and can perform high-precision linear correction for various nonlinear input signals. The control output has remote transmission output; after multiple comparison, the highest measurement point is used as the output (remote transmission output). The output circuit is all optically isolated, with good anti-interference ability. It has high-brightness LCD liquid crystal display. The shell is made of aluminum alloy, and the whole machine adopts wall hanging structure (width x height x depth = 110 x 160 x 60mm), which is very convenient to install.
