At International Process Solutions, we provide precision humidity calibration services tailored to meet the stringent demands of industries that rely on accurate environmental monitoring. As a trusted name in calibration and metrology, we specialize in ensuring that your humidity measurement instruments perform within exact specifications, minimizing risk and supporting compliance with international quality standards.

Why Accurate Humidity Calibration Matters

Accurate humidity measurements are critical in sectors such as pharmaceutical manufacturing, biotechnology, aerospace, semiconductors, food processing, and cleanroom operations. Deviations in humidity readings can result in product degradation, process instability, regulatory non-compliance, and increased operational costs. Our services are designed to ensure that your humidity sensors, transmitters, hygrometers, and data loggers function at peak precision under all environmental conditions.

Scope of Our Humidity Calibration Services

We offer comprehensive humidity calibration for a wide range of instruments, including but not limited to:

• Capacitive humidity sensors
• Dew point meters
• Chilled mirror hygrometers
• Relative humidity data loggers
• Humidity probes and transmitters
• Psychrometers
• Environmental chambers
• Temperature/humidity integrated devices

Calibrations can be performed at multiple relative humidity points (commonly 10%, 30%, 50%, 75%, and 90% RH) across temperature ranges from -20°C to +80°C, simulating the full scope of real-world applications.

Accredited Calibration Services with ISO/IEC 17025 Compliance

International Process Solutions is ISO/IEC 17025:2017 accredited, providing the highest level of calibration confidence. Every calibration is traceable to NIST (National Institute of Standards and Technology), ensuring consistency, reliability, and audit-ready documentation.

Our calibration procedures are performed under controlled environmental conditions using precision humidity generation systems. We employ state-of-the-art calibration chambers, reference hygrometers, and automated data acquisition systems to ensure measurement integrity.

Customized Calibration Protocols for Regulated Environments

Industries subject to FDA 21 CFR Part 11, ISO 14644, EU GMP Annex 1, and USP <1118> require not only calibration accuracy but also rigorous documentation and data handling. Our team is experienced in delivering calibration services aligned with GMP and GLP requirements, including:

• Electronic record-keeping and secure certificate delivery
• Audit trail compatibility and digital backups
• Sensor performance analysis and trend reporting
• Change control documentation for validated environments

Environmental Chamber Calibration and Mapping

Our humidity calibration services extend to entire environmental chambers, incubators, stability rooms, and walk-in units. We perform multi-point humidity and temperature mapping in accordance with ICH Q1A guidelines and WHO TRS 961, providing:

• 3D grid temperature and RH profiling
• Sensor validation and uniformity checks
• Detailed mapping reports with deviation analysis
• Corrective action recommendations for non-conformities

High-Accuracy Reference Instruments and Calibration Equipment

We utilize precision chilled mirror hygrometers, gravimetric generation systems, and two-pressure/temperature-controlled humidity generators from industry leaders such as MBW, Thunder Scientific, and Rotronic. These instruments serve as our primary references, ensuring that all calibrations maintain exceptionally low uncertainty levels.

Calibration Uncertainty Levels We Offer:

• ±0.5% RH for standard calibration
• ±0.2% RH for high-accuracy applications
• ±0.1°C for temperature at RH calibration points

Digital Calibration Certificates and Asset Management

Each calibration is documented with a digital, tamper-evident certificate, which includes:

• Instrument details (serial, model, location)
• Environmental conditions during calibration
• Calibration points and deviations
• Measurement uncertainties
• As-found and as-left values
• Technician credentials and method references

We also offer access to a secure online calibration portal, where clients can:

• Download certificates anytime
• Track instrument due dates
• Schedule recurring calibrations
• Access compliance history
