H1N Indoor temperature and humidity transmitter


الوصف

Applications & Features

Apply for indoor air T/RH measurement with good performance digital sensor & circuit. The sensor is 100%

field changeable without re-calibration Good long-term stability, reliability and fast response State of art housing. All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring Multiple outputs optional, over voltage and reverse polarity protection, and good anti-interference capability LCD & function keys can set parameters and calibrate output, so the product can be a stand-alone controller.
