HT-LH354 Humidity Meter

Product Overview:

Open the cover and the OLED active light display makes the operation simple and convenient. The integrated design is easy to install and reduces the influence of external interference on the measured value. The original imported sensor has the characteristics of high measurement accuracy, weak acid resistance, strong anti-interference ability, long service life and stable and reliable performance. The menu lock function prevents the instrument parameters from being changed by accident and affecting its performance.
