4-Channel Thermocouple Thermometer

This digital thermometer measures four temperature points simultaneously using K, J or T-type thermocouples. It is built for HVAC technicians, laboratory staff, industrial inspectors and anyone needing multi-point temperature data in the field or on the bench.

USB Data Logging with 5000-Record Buffer

The device connects to a PC via USB for continuous logging and supports Windows 7 through 11. Software enables curve analysis and export to Excel or PDF while the internal buffer stores up to 5000 groups of readings for unattended sessions.

Adjustable Alarm with Visual and Audible Alerts

High and low temperature limits can be set per channel; exceeding them triggers a flashing light and beep. The thermometer covers K-type from -328°F to 2501°F, J-type to 2192°F and T-type to 752°F, matching the Celsius ranges of -200°C to 1372°C, 1200°C and 400°C respectively.

Questions about this item

How do I set up the USB data logging on Windows 10?

Connect the thermometer via USB, install the supplied PC software on Windows 10, then start continuous logging to capture up to 5000 reading groups for Excel or PDF export.

What thermocouple probes will need replacing over time?

The four included K-type probes are consumables; replace them when the tip degrades or insulation cracks to maintain accuracy across the -200 °C to 1372 °C range.

At what temperature does the K-type range stop reading?

The K-type thermocouple input tops out at 1372 °C (2501 °F); sustained exposure beyond that exceeds the specified measurement limit.
