Environmental Monitoring Sensors For Critical Industries

Why Environmental Monitoring Matters

In critical industries across the science and manufacturing fields, the sensors used in environmental monitoring play a key role in ensuring compliance, product integrity, and safety.  Whether you work in pharmaceutical manufacturing, biotech research, hospitals, blood banks, or cleanrooms, maintaining stable conditions ensures compliance, product integrity, and safety.

At Rees Scientific, we specialize in temperature sensors, humidity sensors, gas detection sensors, pressure monitoring, and more, helping clients across industries achieve regulatory compliance and operational efficiency. While many of our clients use our sensor catalog as a reference, Rees Scientific can support virtually any monitoring need with custom solutions.

Why Are Environmental Monitoring Sensors Important?

Environmental fluctuations can compromise research results, damage sensitive materials, and pose risks to safety. The right sensors help prevent costly failures by providing real-time monitoring, automated alerts, and historical data tracking for regulatory audits.

What types of sensors does my facility need for compliance?

The sensors required for compliance depend on industry regulations, facility type, and specific environmental needs. FDA, CDC, USP <797>, ISO 14644, and other regulatory bodies set strict guidelines on environmental monitoring. Rees Scientific offers expert guidance to help facilities choose the right monitoring solutions. 

1. Temperature and Humidity Sensors: Maintaining Stability in Critical Environments

Industries: Pharmaceuticals, Biotechnology, Blood Banks, Research Labs, Hospitals, Cleanrooms

Temperature and humidity control is vital for biologics, vaccines, blood products, and laboratory research. Fluctuations can render samples unusable or cause regulatory violations.

Best Sensors for Temperature and Humidity Monitoring:

• RTD Temperature Sensors & Thermocouples – Used in cryogenic storage, freezers, and pharmaceutical stability chambers.
• Temperature/Humidity Transmitters – Monitor incubators, walk-in refrigerators, and lab freezers to prevent temperature excursions.
• Temperature Blocks – Ensure accurate cold storage temperature readings by mimicking product temperatures.

Does Rees Scientific provide documentation to meet compliance requirements?

Yes! We provide ISO 17025-certified calibration services, validation documentation, and compliance reports to support regulatory audits.

2. Gas Sensors: Protecting Air Quality and Workplace Safety

Industries: Research Facilities, Cleanrooms, Manufacturing, Hospitals and IVF Labs

Gas sensors play a critical role in detecting harmful or hazardous gases to ensure safe working conditions.

Best Gas Sensors for Environmental Safety:

• Carbon Dioxide (CO₂) Sensors – Used in incubators, greenhouses, and medical research labs.
• Oxygen Sensors – Monitor freezer farms, liquid nitrogen storage, and confined spaces for oxygen depletion.
• Ammonia Sensors – Essential for animal research facilities using ventilated cage racks.
• Combustible Gas Sensors – Protect industrial labs and hazardous storage areas from flammable gas leaks.

What compliance standards require gas monitoring?

Regulations such as OSHA standards, USP <797>, and FDA Good Manufacturing Practices (GMP) mandate continuous gas monitoring in laboratories, research facilities, and pharmaceutical manufacturing environments. 

3. Airflow and Pressure Sensors: Ensuring Cleanroom Compliance

Industries: Cleanrooms, Compounding Pharmacies, Hospitals, Data Centers, Animal Research

Controlling airflow, ventilation, and pressure differentials is essential in regulated environments such as cleanrooms, sterile manufacturing, and hospitals.  Maintaining positive or negative air pressure is crucial in sterile environments to prevent contamination.

Best Airflow & Pressure Sensors:

• Differential Pressure Transmitters – Maintain proper clean room air balance.
• Air Velocity Sensors – Monitors airflow in cleanrooms, animal research facilities, and other regulated environments ensuring air changes per hour meet standards.
• Large Diaphragm Pressure Switches – Help maintain HVAC efficiency and compliance with ISO standards.

What standards regulate airflow and pressure monitoring?

• ISO 14644 (for cleanrooms)
• USP <797> and <800> (for compounding pharmacies)
• FDA Good Manufacturing Practices (GMP)

4. Water, Light, and Motion Sensors: Specialized Monitoring for Critical Areas

Industries: Laboratories, Data Centers, Animal Research, Pharmaceutical Storage

In addition to temperature and gas monitoring, certain industries require specialized sensors to track other environmental conditions.

Best Specialty Sensors:

• Surface Water Detectors – Alert facilities to water leaks before costly damage occurs.
• Light Sensors – Ensure consistent lighting conditions in research environments.
• Rotation and Shaker Sensors – Ensure proper function of platelet rotators and lab shaker tables.

How do light and water sensors support regulatory compliance?

• Light Sensors ensure research animals receive consistent lighting cycles required for GLP compliance.
• Surface Water Detectors prevent water damage in data centers, labs, and pharmaceutical storage areas, protecting against equipment failure and regulatory violations.
