1、ACCURATE MEASUREMENT: This sensor probe has an accurate measurement performance, with a humidity accuracy ± 1.5% RH, and temperature accuracy ± 0.1 ℃. 2、COPPER, PLASTIC MATERIAL: Made of premium copper and plastic material, this sensor is strong and sturdy, wear resistant and can withstands harsh environments. 3、APPLICABLE SCENARIOS: Suitable for measurement of temperature and humidity of agricultural greenhouse, flowers, nursery, soil, etc. 4、EASY USE: This temperature sensor probe is small in size and light in weight that you can easily carry and install it for convenient use. 5、USE INDICATION: The sensor performs normally within the recommended operating range, and long term exposure to conditions outside the normal range, especially when humidity is greater than 80 percent, may cause temporary signal drift (drift+3% RH after 60 hours). When normal operating conditions are restored, the sensor will slowly self recover to the calibration state. Prolonged use under abnormal conditions will accelerate the aging of the product.
