Precision for Pharmaceutical Purity
Pharmaceutical manufacturing demands temperature sensors that meet strict regulatory requirements for product contact surfaces, cleanability, and measurement accuracy. From active pharmaceutical ingredient (API) synthesis to final fill-and-finish operations, accurate temperature control directly impacts product quality, safety, and regulatory compliance.
Thermometrics manufactures 3-A sanitary temperature sensor assemblies with electropolished surfaces, tri-clamp connections, and FDA-compliant materials for pharmaceutical, biotech, and life science applications. Every sensor is available with NIST-traceable calibration and comprehensive documentation packages to support your GMP quality system and IQ/OQ/PQ validation protocols.
3-A Sanitary Standards
Our sanitary sensor assemblies conform to 3-A Sanitary Standards for product contact surfaces. All wetted surfaces are 316L stainless steel with Ra ≤ 0.8 μm (32 μin) electropolish finish. Self-draining probe designs prevent product holdup and support CIP/SIP protocols.
NIST-Traceable Calibration
Every pharmaceutical sensor can be supplied with NIST-traceable calibration per ANSI/NCSL Z540.3. Calibration certificates include uncertainty statements, reference standard traceability, and as-found/as-left data for your validation documentation packages.
Pharmaceutical Applications
Our pharmaceutical temperature sensors support critical measurement points throughout the drug manufacturing process, from raw material receipt through final product storage and distribution.
Validation & Qualification
Temperature mapping and qualification sensors for IQ/OQ/PQ validation protocols. High-accuracy RTD probes (±0.1°C) for autoclave, lyophilizer, and clean room temperature validation studies. Multi-point configurations for thermal uniformity surveys.
Clean Room Monitoring
Continuous temperature and humidity monitoring for ISO Class 5-8 clean rooms and controlled environments. Wall-mount, duct-mount, and immersion configurations compatible with building management and environmental monitoring systems (EMS).
Autoclaves & Sterilizers
Penetration probes and chamber sensors for steam autoclave and dry heat sterilizer qualification and routine monitoring. Fast-response elements with time constants under 3 seconds for accurate tracking of sterilization cycle profiles.
Bioreactors & Fermenters
Sanitary immersion RTD sensors for bioreactor temperature control during cell culture and fermentation processes. Tri-clamp connections with CIP/SIP-compatible designs and 4-20mA transmitter output for DCS integration.
Cold Storage & Distribution
Temperature monitoring for pharmaceutical cold chain: walk-in coolers, freezers, cryogenic storage (-80°C), and refrigerated transport. Wireless and hardwired configurations with alarm capabilities for 2-8°C and -20°C storage ranges.
Reactors & Mixing Vessels
Jacketed reactor and mixing vessel temperature sensors with flush-mount and immersion configurations. Dual-element RTD assemblies for redundant measurement in critical API synthesis reactions with Hastelloy or tantalum wetted parts for corrosive reagents.
