The Altronic ETM-40US Universal Temperature Monitor/Scanner is a microprocessor-based instrument designed to monitor up to forty process temperatures. While primarily designed for use in monitoring critical temperatures on reciprocating engines and compressors, the incorporation of 10-36VDC or 100-250VAC power, the suitability for use with either J or K thermocouples, and a wide variety of input and output module options allows for the application of the ETM-40US to virtually any industrial process requiring state-of-the-art temperature protection.
