USBwith LCD displayfor food applications

· 32-bit high-speed low-power MCU · Four channels · K, T and J type thermocouple supported · Resolution up to 0.01℃ · Factory accuracy ±(0.3%|t|+0.40)℃ · Accuracy up to ±0.1℃ after point calibration · Measuring range -200℃~+1370℃ 【DESCRIPTION】 YET-640 is with principle of thermocouple temperature measurement, which is an instrument used to measure temperature. This instrument uses cyclic measurement technology, therefore the sample rate can still be 2 times per second while four channels are working simultaneously with low power consumption. Benefit by the internal high precious circuit principle and high precious reference source of the instrument, coupled with accurate factory calibration, the resolution of the instrument can be reached 0.01℃, and the factory accuracy can be reached ±(0.3%|t|+0.40)℃. Four channels to be measured temperature is supported by YET-640, and temperature graph can be displayed in single channel mode. Point calibration by users is supported by this instrument, and multiple points calibration can greatly improve the measuring accuracy of it (system composed of instrument and probe). This instrument supports the most commonly K, T and J types of thermocouple probes. The compatibility with multiple types of probes expands the application fields of the instrument. YET-640L adds recording function on the basis of YET-640. YET-640L can record all the data during temperature measurement. The files generated while recording can be viewed directly on this machine or on any device that U disk supported.
