EX-1 Exhaust Temperature Monitor/AlarmThe EX-1 continually displays the exhaust gas temperature in wet exhaust systems giving advanced warning of potential problems. The EX-1 measures the exhaust gas temperature directly and displays it in degrees centigrade or Fahrenheit. Once the normal working temperature has been established a maximum temperature, a few degrees higher, can be programmed into the EX-1 which will then sound an alarm if that temperature is exceeded.Even a small rise in temperature can indicate a potential problem such as a minor blockage, leak or failing pump which can be corrected before a complete failure occurs.Technical Specifications Compact size 125 x 62 x 23mm with high contrast LCD Supply current less than 1.5mA Supply Voltage 8 to 15 volts DC.
