Grande Expertise in Humidity Control
Controlling humidity in a small environmental chamber can be especially challenging. Grande expertise in humidity control brings intelligent design that is carefully integrated into the Criterion chambers. The humidity subsystems are designed for reliability, convenience, and performance:
An external steam generator allows expanded range and is easy to maintain.
A separate de-humidification coil improves low humidity control and range.
Wet-bulb humidity sensor is a �??primary measurement method�?? for accuracy. It is also economical, easy to maintain, and reliable because it has no risk of failure due to over-saturation. (Read why analog is preferred over digital.)
Direct water supply connection is standard, with options for water filtering and recirculating water tank.
