Humidity Monitoring Sensors
Control. Compliance. Confidence.
Humidity plays a critical role in the stability, safety, and quality of products and environments in pharmaceutical, biomedical, and research settings. Inaccurate or inconsistent humidity levels can lead to equipment malfunctions, compromised materials, failed audits, or even health risks. At Rees Scientific, we offer a range of high-accuracy humidity monitoring solutions designed to meet the strict demands of regulated facilities, helping you maintain control, demonstrate compliance, and operate with confidence.
Why Humidity Monitoring Is Essential
Whether you're protecting freeze-dried drugs in a cleanroom or maintaining animal welfare in a vivarium, humidity is not just an environmental concern, it's a compliance requirement. Even small fluctuations in humidity can:
- Impact product stability or chemical composition
- Compromise sterility in cleanroom or production areas
- Affect the comfort and well-being of lab animals or personnel
- Interfere with the operation of sensitive lab and manufacturing equipment
- Trigger false alarms or improper environmental responses
Failure to monitor and control humidity can result in:
- Failed GMP or GxP audits
- Regulatory fines or recalls
- Product loss or quality degradation
- Environmental health and safety violations
Comprehensive Humidity Monitoring Solutions
Rees Scientific provides a full spectrum of humidity monitoring solutions to meet the diverse needs of highly regulated environments. Our sensors are engineered for high accuracy, reliability, and compatibility with both wired and wireless systems.
Room Mount Humidity Sensors
Ideal for maintaining stable humidity in ambient environments, these sensors support critical room-temperature spaces where compliance and product integrity matter.
Applications:
- Compounding pharmacies and clinical labs requiring USP <797>/<800> compliance
- Pharmaceutical manufacturing areas with ambient environmental controls
- Medical device and reagent storage rooms sensitive to humidity fluctuations
- Cleanroom gowning or transition zones where stable conditions are critical
Combination Temperature & Humidity Sensors
Many of our sensors combine temperature and humidity monitoring in a single probe, minimizing wiring and simplifying installation. These sensors are ideal for clients who need full environmental oversight at every monitoring point.
Applications:
- Cleanrooms requiring consolidated sensor profiles
- Remote storage spaces with limited access
- GMP warehouses or cold storage with humidity control
Available in:
- Standard and cleanroom configurations
- Certified (ISO 17025) and washdown-safe models
- Remote probes for hard-to-reach or enclosed areas
- Triple-sensor configurations (Temp, RH, Light)
High-Temperature / High-Humidity Sensors
Designed for harsh environments where typical sensors fail, these models provide reliable performance even in areas with elevated humidity or temperature.
Applications:
- Stability chambers
- Hot humid incubators
- Environmental test rooms
- Animal holding areas with heat and moisture fluctuation
Duct Mount Humidity Sensors
Our duct-mounted humidity sensors offer robust and accurate humidity monitoring for HVAC-integrated environments.
Applications:
- Cleanroom HVAC ducts for environmental control
- Production suites in pharma and biotech
- Hospital and lab HVAC zones requiring ISO-class compliance
Supporting Your Regulatory Needs
All Rees Scientific humidity sensors are built to meet the stringent documentation and validation needs of regulated industries.
Our humidity sensors support:
- GMP and GLP standards
- FDA 21 CFR Part 11 compliant data handling
- USP <797>, <800>, and <1079> guidelines
- ISO 17025 calibration traceability (available on select models)
- Environmental monitoring protocols for AABB, CAP, and The Joint Commission
Calibrated sensors and NIST/ISO certificates are available to ensure validation and audit readiness.
Seamless Integration and Scalable Architecture
Humidity sensors from Rees Scientific are easily integrated into your larger Rees Monitoring System. Whether you’re starting with one room or planning enterprise-wide monitoring, our systems grow with you. Data from your humidity sensors is:
- Collected in real time
- Digitally transmitted to your dashboard or Building Management System (BMS)
- Stored with full traceability
- Configurable for alerts, reports, and compliance audits
Wireless and wired options allow for flexible deployment, even in legacy buildings or new construction.

Humidity Mapping Services
Validate Uniform Conditions. Meet Compliance Expectations.
Humidity mapping is the process of measuring and documenting relative humidity distribution across a controlled environment. It’s a critical component of initial facility validation, seasonal requalification, and deviation investigations. Rees Scientific provides comprehensive humidity mapping services to help ensure that storage areas, chambers, and cleanrooms maintain consistent humidity levels throughout.
