Description
Portable K-Type Thermocouple Thermometer – EZDO | YC-311 / YC-321
The EZDO YC-311 and YC-321 portable K-type thermocouple thermometers are designed for wide-range temperature measurement in industrial, laboratory, HVAC, and research applications. The K-type thermocouple sensor covers an exceptional measurement range from -200°C to +1372°C, accommodating everything from cryogenic to high-temperature furnace measurements in a single handheld instrument.
The microcontroller-based 4-digit LCD design delivers high accuracy and stability with a reading update rate of 4 times per second. Max, Min, and Avg values can be displayed simultaneously with the live reading, supporting both peak capture and averaging workflows. A data hold function freezes the current display, and the REL (relative) function enables differential measurements from a reference point. Automatic power-off with disable option, 0°C digitized correction, and selectable °C/°F units complete the practical feature set. The YC-321 adds a second thermocouple input, enabling simultaneous T1 and T2 measurement and T1-T2 differential display — particularly useful for heat transfer studies, gradient measurements, and comparative temperature work.
