Our Humidity Calibration Services

Humidity measurement plays a vital role across industries such as pharmaceuticals, electronics manufacturing, food processing, environmental monitoring, and materials testing.

When humidity instruments drift out of specification, the consequences can be significant—process failures, contamination issues, product spoilage, regulatory violations, and increased operational costs. The Accredited Labs network provides comprehensive humidity calibration services to keep your instruments performing within their required accuracy ranges.

Our Process 

Humidity calibration involves verifying and adjusting instruments that measure relative humidity, absolute humidity, dew point, and moisture content across defined operating ranges. Each device is compared to certified reference standards with known, traceable humidity values to identify any deviations from its intended performance.

Skilled technicians use precision humidity generators and calibrated reference instruments to evaluate performance across varying environmental conditions and the instrument’s full measurement range. They document all variations and may make the adjustments required to restore accuracy. If an instrument cannot be restored to the required accuracy range, you receive detailed reporting with the data needed for maintenance planning, uncertainty calculations, or informed replacement decisions.

All humidity calibrations follow internationally recognized standards and industry best practices that promote consistency, reliability, and complete measurement traceability. Each instrument is returned with documentation linking its accuracy to national humidity measurement standards—supporting environmental regulations, quality management systems, and process control requirements.

Types of Humidity Measuring Instruments We Calibrate

Our comprehensive humidity calibration services cover the complete spectrum of moisture measurement instruments used across industries:

  • Digital Humidity Transmitters: Electronic instruments that provide precise humidity readings with analog or digital outputs for process control and monitoring systems. These instruments require calibration of sensors, signal processing electronics, and output characteristics to ensure accurate humidity measurement and reliable system integration.
  • Portable Humidity Meters: Handheld instruments used for spot measurements, facility surveys, and field applications that require calibration across their measurement range and various environmental conditions. These versatile instruments support quality control, environmental monitoring, and maintenance applications with portable convenience.
  • Hygrometers and Psychrometers: Traditional humidity measurement instruments including wet-bulb/dry-bulb psychrometers and mechanical hygrometers that require specialized calibration procedures accounting for their measurement principles and environmental sensitivities.
  • Data Loggers with Humidity Sensors: Automated monitoring systems that record humidity measurements over time for environmental monitoring, validation studies, and compliance documentation. Calibration ensures accurate data collection and timing precision for extended monitoring applications.
  • Dew Point Meters: Specialized instruments that measure dew point temperature for applications requiring absolute humidity determination, compressed air quality monitoring, and process control in industrial applications where dew point is the critical measurement parameter.
  • Moisture Analyzers: Laboratory instruments that determine moisture content in materials, products, and samples using various measurement techniques. These instruments require specialized calibration procedures that address both the humidity measurement and sample handling characteristics.
  • Environmental Chamber Controllers: Humidity control systems used in environmental chambers, stability testing equipment, and controlled atmosphere storage that require calibration of both measurement and control functions for precise environmental management.
  • HVAC Humidity Sensors: Building automation sensors used for climate control, indoor air quality monitoring, and energy management that require calibration for accurate environmental control and energy-efficient operation.
  • Cleanroom Monitoring Systems: Specialized humidity monitoring equipment designed for pharmaceutical cleanrooms, electronics manufacturing, and sterile environments that require calibration procedures compatible with cleanroom protocols and contamination control.
  • Industrial Process Humidity Monitors: Robust instruments designed for manufacturing environments including paper mills, textile plants, and chemical processing facilities that require calibration under challenging industrial conditions.
