• Digital display (LED)
• Anti-RFI-Certification(especially for intercom)

Field of application

• MS151 Series multi-channel temperature monitor 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 .
• Input type : Pt100,Cu50(TC if specially required)
• Measuring Points : 4,6 points
• Temperature at any measuring point can be displayed by operating the keys on panel,The corresponding indicator light above the key is on at the same time.
• Hint signal for sensor fault can be sent out in the form of high alarm or low alarm.
