  • Introduction
  • Specifications
Integrated instrument-specific chips, with more reliable anti-interference and stability of\
Universal signal input through the menu settings can be assigned access commonly used thermal signal.
Modify the display range on line , transmission output range, alarm values and alarm mode.
Hardware and software combination of anti-jamming mode, effectively inhibit the site interfering signals
Digital calibration techniques, non-adjustable components such as potentiometers.
Automatically compensates of thermocouple cold junction temperature and thermal resistance of lead resistance.
Can supply power distribution function for the second and third-wire transmitter
With RS232 or RS485 communication functions, using standard MODBUS RTU protocol to connect with the host computer may constitute a data acquisition system and control system.
