Meokon digital temperature and humidity sensor Transmitter MD-HT with RS485 and 4-20mA

Short Description:

MD-HT101 series digital temperature and humidity sensors adopt imported temperature and humidity sensors as sensitive components, which can quickly respond to charges in temperature and humidity.

This product adopts 3.5″ LCD screen display and is equipped with a mounting bracket for easy wall-mounted installation.

This series of products include 4~20mA current(HT101A), RS485(HT101R) two output options, the products supports ºC,ºF unit switch/display digits/range configuration. MD-HT101R supports button configuration unit switch/communication address/baud Rate/filtering constant, etc. This series of products have high accuracy, fast response and long life, especially suitable for indoor occasions where high-precison measurement of temperature and humidity is required.
