S904 Humidity Validator
Cost-effective, transportable humidity calibrator with 5 interchangeable probe ports.
Key Features
- 5 interchangeable ports for virtually any brand/model of humidity sensor
- Generates 10 to 90% RH over +10 to +50 °C
- Excellent chamber stability and uniformity
- Manual control or optional automated set-point programming
- Optional in-built data-logging for reference and test probes
- Simple operation and maintenance
- Transportable for on-site calibrations
Overview
The S904 is a stand-alone, transportable humidity calibrator built to be easy to use and maintain. Its calibration chamber features 5 interchangeable ports that accommodate virtually any brand, type or model of humidity sensor, making it well suited to organizations that need to calibrate large numbers of probes in a lab or field setting.
Working Principle
A humidity- and temperature-controlled chamber generates a stable, uniform test environment across 5 interchangeable probe ports. Probes under test are compared against the chamber's controlled set point, either under manual control or optional automated set-point programming, with optional in-built data-logging for both the reference and probes under calibration.
Applications
Benefits
- Cost-effective option for calibrating large probe volumes
- Interchangeable ports avoid needing separate adaptors per probe brand
- Portable design suits both lab and field calibration work
- Optional data-logging supports calibration record-keeping
