Modern research and laboratory environments demand precise control and monitoring of environmental parameters (temperature, humidity, pressure). The deviations can affect experiments, sample stability, calibration, or instrument drift. This white paper describes how STN’s instrumentation enables accurate, traceable measurements; integrates into lab workflows; and contributes toward improved data integrity, reproducibility, and operational efficiency.
Introduction
- The critical importance of environmental conditions in laboratory and research settings
- Common challenges: variations in humidity, temperature gradients, atmospheric pressure fluctuations
- Overview of STN Instruments’ thermohygrometer
Technical Capabilities & Design
- Sensor performance — high-accuracy sensors, low drift, fast response
- Calibration traceability — factory calibration, traceability to standards, re-calibration support
- Multi-parameter measurement — ability to measure temperature, relative humidity, barometric pressure in one device
- User interface — backlit displays, data hold, min/max, alarms
- Form factor & usability — handheld, compact, rugged designs suited to lab or field
Applications in Laboratory & Research Settings
- Stability testing (e.g. pharmaceuticals, biologics)
- Cleanrooms and environmental chambers
- Instrumentation enclosures (e.g. inside spectrometers, analyzers)
- Environmental monitoring for sample storage rooms
- Field-to-lab transitions: portable measurement in situ
Case Studies
A calibration laboratory specializing in precision mass standards recognized that environmental stability directly affects calibration uncertainty. Small variations in air temperature, humidity, or pressure could lead to measurement errors and non-conformance with ISO/IEC 17025 criteria.
To address this, the lab integrated STN’s Handheld Temperature, Humidity, and Barometric Pressure Meter into its daily environmental verification routine. Technicians performed quick measurements prior to each calibration session to confirm ambient temperature within ±0.5 °C and humidity within ±5% RH.
The use of STN’s calibrated, traceable instruments allowed the lab to quantify environmental contributions to measurement uncertainty, strengthen traceability records, and demonstrate compliance during accreditation audits. The reliability and repeatability of STN sensors reduced the need for frequent cross-checks, saving time and maintaining high confidence in calibration results.
Benefits & Outcomes
- Increased confidence in environmental control and data validity
- Early detection of excursions or failures via alarms
- Reduced downtime and corrective actions
- Enhanced reproducibility of experiments
- Streamlined compliance for standard operating procedures (SOPs), audits, and regulatory requirements
Implementation Recommendations & Best Practices
- Proper placement and installation (avoid drafts, radiant heat, direct sunlight)
- Regular calibration schedule and documentation
- Sensor warm-up times, equilibration, and stabilization
- Training for lab personnel on use, maintenance, and interpretation
Challenges & Mitigation
- Sensor aging, drift — schedule re-calibration, cross-checks
- Environmental gradients inside rooms — deploy multiple sensors, map spatial distribution
