1. The humidity range of the constant temperature and Humidity Chamber
We know that the humidity in a constant temperature and Humidity Chamber is relative, for example, at 30°C, the relative humidity is 50%RH; at 85°C, the relative humidity is 85%RH, and so on, not from the high temperature limit to The low temperature limit versus humidity for the entire temperature range, where low temperature is humidity-free.
There will be some customers who have lower humidity requirements for programmable constant temperature and Humidity Chambers, such as 15%RH or 5%RH low humidity requirements, etc., but few people ask about the 0%RH humidity range. Because we all know that 0%RH humidity means no humidity requirement.
Just as the high humidity of 98%RH is better than the humidity of 100%RH, because the humidity of 100%RH indicates that the moisture is saturated, and the saturation is equal to water.
2. When the constant temperature and Humidity Chamber is set to 0°C, what is the humidity?
It depends on whether the operator has set the temperature to 0 °C or the humidity to 0% relative humidity (RH).
If the set temperature value is 0, that is, there is no humidity, this type of equipment cannot be used, because temperatures below 5°C cannot be done with humidity.
And if the humidity is set to zero, there will be no humidity. Generally, the humidity range of constant temperature and humidity environmental test equipment is 20%98%RH. The so-called relative humidity is generated at relative temperature. Not all temperatures can have humidity. There is moisture drying or evaporation, such as high temperature above 90 ℃, basically no humidity. Humidity below the usual humidity of 5°C is impossible, as the temperature is low and the moisture in the air would frost or freeze, so humidity at 0°C is impossible.
