Metal pipeline current type temperature and humidity transmitter, the product adopts capacitive digital sensor as the temperature and humidity measurement component, and is equipped with a stable and reliable signal processing circuit to convert the temperature and humidity in the environment into the corresponding standard signal. Choose The quality integrated digital temperature and humidity sensor ensures the long-term stability, low delay and strong resistance to chemical pollution of the transmitter, and the repeatability of the transmitter. It can be widely used in the monitoring of environmental temperature and humidity in textiles, food, scientific research, environmental protection, warehouses, weather stations (stations), workshops, workshops, warehouses, libraries, offices, computer rooms, laboratories, greenhouses, etc. Long-term stability, wide temperature measurement range, accurate high and low temperature measurement, small size, light weight, high measurement accuracy, and fast response speed Temperature measurement range (can be set by dial code): 0~50℃/-20~80℃/-40~60℃/-40~120℃ Accuracy: (25℃)±0.3℃ Resolution: 0.1℃ Long-term stability: less than 0.1℃/year Relative humidity range: 0~99.9%RH Accuracy (including non-linearity, hysteresis and repeatability): ±3%RH Factory calibration uncertainty: ±0.6%RH (0~40%RH)/±1.0%RH (40~97%RH) Working environment temperature: -40~120℃ Working environment humidity: 0~99.9% non-condensing Working voltage: 12~30V size:Length 200mm diameter 15mm Material:metal colour:Silver Package Contents: 1 x sensor probe (with cable) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
