The Triplett TMDL400 is a four-channel Type K thermocouple datalogger for comprehensive temperature monitoring. The backlit LCD simultaneously displays temperature readings across four channels, along with the date and time. The T1-T2 button allows for displaying channel 1 and channel 2 only. The versatile functionality of the TMDL400 enables measurements of surface temperatures of solids and liquids, and ambient air temperature. It has a temperature range of -328 to 2498°F (-200 to 1370°C).

The TMDL400 can data log multiple files, each containing up to 30,000 readings, with a customizable sampling rate between 1 second to 90 minutes. Features include a programmable start time, user-configurable audible and visual high/low alarms per channel, and an adjustable offset for probe compensation. Also included are Min/Max recording capabilities, a Data Hold function, and an auto power-off feature with disable function to conserve battery life.

The wall-mountable TMDL400 includes four Type K thermocouple bead probes, an SD card, four AA batteries, and a universal AC adapter (100-240V) with three plugs (US, UK, EU).
