Features and advantages
l Supports Modbus RTU protocol
l Supports connecting RS485 serial port for upgrade
l Supports 1 temperature acquisition, and retains one decimal digit when the screen displays the acquisition results in degrees Celsius (℃). The measurement range is-20.0℃~75.0℃, and the typical accuracy is ±0.3℃@25℃
l Supports 1 humidity acquisition, and the screen displays the acquisition results with one decimal number retained in percentage form (%). The measurement range is 5~95% RH, and the typical accuracy is ±3.0% (20%~80%RH@25℃)
l Supports 1 dew point temperature acquisition, and retains one decimal digit when the screen displays the acquisition results in degrees Celsius (℃). The measurement range is-40.0℃~75.0℃, and the typical accuracy is ±0.3℃@25℃
l Supports custom setting of temperature and humidity upper limit alarm threshold and temperature and humidity lower limit alarm threshold. When the specified threshold is exceeded, an alarm point value will be generated
l Support mechanical button setting, easy to operate
l Support the function of button lighting up the screen (backlight), which is clear and intuitive
