Maretron's TMP100 measures the temperature for up to 6 temperature probes and reports the information over an NMEA 2000 network. The TMP100 supports up to 4 thermistor probes and 2 high temperature thermocouple probes. Optional thermistor probes 20 deg. C to 80 deg. C or 4 deg. F to 176 deg. F cover a wide range of applications including cabin air temperature, engine room air temperature, refrigerator/freezer temperature, under bolt temperature inverters, charges, pumps, motors, etc , tank temperatures live well bait, hot water, etc and air duct temperatures. The optimal thermocouple probes 0 deg. C to 900 deg. C or 32 deg. F to 1652 deg. F are used to measure Exhaust Gas Temperature EGT as part of a comprehensive fuel management system.
