1Support thermocouple, thermal resistance, voltage, current and two-wire transmitter input; suitable for various physical displays such as temperature, pressure, liquid level, length, etc. 2Adopt high-brightness LED digital display, at the same time adopt high-accuracy 40-line light column display, clearly and intuitively display the measured value. 3Supports up to four alarm functions, including two upper limit and lower limit alarms, which can be independently alarmed, more convenient and practical to use. 4Using advanced non-jumping technology can freely change the index number. It can perform high-accuracy linear correction on various nonlinear signals. 5With a variety of standard serial two-way communication functions (for RS232C, for RS-485, for RS-422, etc.) with intelligent data collector and configuration software support for Windows XP platform, it can achieve networking with the host computer.
