MS150 Series multi-channel temperature monitor is a multi-point temperature measurement instrument. It takes the highest measured temperature in measuring loops as its output signal which is sent out in the form of a 4 to 20 mA standard current signal and the temperature is displayed by the built-in LED. If required, temperature at any measuring point can be shown by operating the keys on panel. Isolation is provided between the input and output. It is mainly used in the applications of multi-point temperature measurement or alarm warning system. By adopting SMT technology, it offers excellent accuracy, reliability and anti-disturbance.
