The Pax Instruments is a logging thermometer with four thermocouple inputs, USB connectivity, and MicroSD storage. It supports K type thermocouple.
Hardware
Microcontroller: ATmega32U4, 8 MHz, 3.3 V ADC: MCP3424 Junction temperature: MCP9800 Screen: 132x64 LCD
Protocol
The T400 output CSV data in ASCII format over a USB serial port. Upon device boot or when a new log file is starter a header is also output.
Here is a sample of serial output when a new logging session has started.
