5128A RHapid-Cal®

The 5128A RHapid-Cal® provides industry-leading system accuracy of ±1.0% RH (7% to 80% RH, 18°C to 28°C), including all known error sources such as stability, uniformity, drift and calibration uncertainty. Calibrate with confidence using an instrument with complete specifications. Most competing generators do not state system accuracy; their specifications can be complex and confusing, making them difficult to apply to an accurate calibration process.
The 5128A also provides the flexibility to improve calibration uncertainty by using an external humidity reference, such as a chilled-mirror hygrometer.
