The MCP9800 temperature sensor is used for cold junction compensation.
The MCP3424 analog-to-digital converter measures the voltage produced by each thermocouple.
The DS3231 real time clock is used to trigger readings. Between readings the device is put into low power sleep mode. The RTC wakes up the unit to take a reading. This gives a longer battery life.
The T400 uses a standard BL-5C battery. This is great for battery replacement in the field.
The generous 132×64 LCD is capable of displaying the current temperature for each thermocouple as well as a graph of the most recent readings.
Thermocouples connect via standard mini thermocouple connectors. The T400 is compatible with a wide variety of K-type thermocouple sensor types from stainless steel probes to rolling surface-contact sensors.
