Nasa Marine EX ~1 exhaust temperature monitor/alarm
The 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.
