YET-640X High Accuracy 4-Channel Thermocouple Temperature Data Logger with PC Real-time Monitoring
Description
The YET-640X high-precision 4-channel thermocouple data logger simultaneously measures 4 temperature points via K/T/J type thermocouples with 2 times/second sampling rate for boiler monitoring, multi-zone industrial process and laboratory multi-point temperature testing. This multi-channel thermocouple thermometer supports -200~1370℃ wide range, 0.01℃ resolution, multi-point calibration and 20000-group recording capacity with PC software for real-time chart analysis and data export. The professional temperature monitoring system features cyclic measurement technology, temperature curve display, over-limit buzzer alarm and multiple export formats for comprehensive industrial temperature data acquisition.
