The most critical task in humidity measurement is to stably detect the correct humidity level within an acceptable response time. It must cover the entire measurement range from 0% RH to 100% RH. Needless to say, the stability of the humidity sensor should remain unchanged, even if it is operated for a longer period of time under higher conditions. The temperature and environmental effects of individual applications have a major impact on the long-term stability of the sensor. Through specially developed polymers and the use of high-quality materials
HENGKO's multifunctional temperature and humidity sensor is a high-performance industrial temperature and humidity transmitter, suitable for harsh industrial applications. The product adopts high-precision RHT series sensors with high accuracy and strong anti-interference ability, ensuring high measurement performance.

Q: What is the common use of a Temperature and Humidity Sensor?
A: Temperature and Humidity sensors are among the most commonly used environmental sensors. It is widely use to provide the actual humidity condition within air at any given point or in any given place. Such devices are commonly used in situations in which air conditions may be extreme or where air conditions need to be controlled due to varying reasons.Q: Why is Temperature and Humidity Sensor important in some of the industries?
A: Humidity is the presence of water within the air. Measuring humidity within the environment can be critical due to the fact that the higher the humidity, the warmer it may seem. In industries, humidity measurement is often important because it can affect the health and safety of personnel as well as the cost of the product. As a result, temperature and humidity sensors are often quite important.Q: How do I choose a suitable Temperature and Humidity Sensor?
A: There are a some important specifications you might need to consider when you choosing this product. This includes:
* Accuracy
* Long-term stability
* Ability to recover from condensation
* Resistance to physical and chemical contaminants
*Interchangeability
* Repeatability
