- 0.01°C display resolution.
- Scanning speed of up to 10 readings per second.
- Supports J, K, T, E, S, N, B, and R thermocouples.
- 4.3-inch color TFT-LCD for clear presentation of measurement results.
- Numerical readings, curve charts, and histogram display modes.
- Cold-junction compensation for thermocouple measurements.
- Automatic detection of open-circuit thermocouples.
- Individually configurable upper and lower temperature alarms for each channel.
- Visual indication of readings that exceed configured temperature limits.
- USB Host interface and USB storage for recording data and screenshots.
