RH portable calibration cell - for 33%/75% RH CE-310-CAL33, CE-310-CAL75

Low cost effective and accurate calibration standards for RH.

These humidity cells use formulated standard saturated solutions to produce predictable & stable humidity. With this portable calibration set, the operator can perform tests at the location where calibration is needed.

The cell has a semi permeable membrane separating the salt solution from the working test space. Stable temperatures close to 25C are preferred for tests.

• Standard cells for 33% and 75% RH
• Accuracy dependent on ambient temperature - corrections can be applied
• Simple use for small probes - semi permeable membrane -> dry work space
