Overview
The Traceable Calibrated Digital Pocket Thermometer (Model 90205-01) is a compact, handheld precision temperature measurement instrument engineered for laboratory, quality control, and field service applications requiring rapid, reliable, and metrologically traceable readings. Based on high-stability thermistor or platinum resistance sensor technology (depending on probe configuration), the device delivers direct digital output with resolution down to 0.1 °C across its full operational range of −200 °C to +200 °C. Each unit ships with an individual NIST-traceable calibration certificate—documenting as-found and as-left values at multiple temperature points (e.g., −78.5 °C dry ice, 0 °C ice point, 25 °C ambient, 100 °C boiling water), uncertainty budgets, and compliance with ISO/IEC 17025 requirements under accredited third-party calibration. Its pocket-sized form factor, auto-power-off functionality, and IP65-rated housing ensure robustness in both cleanroom and industrial environments.
Key Features
- NIST-traceable calibration certificate included—valid for 12 months from date of issue, with documented measurement uncertainty and reference standard traceability path
- High-accuracy performance: ±0.2 °C over the entire −200 °C to +200 °C range, verified per ASTM E220 and ISO 17025 procedures
- Interchangeable probe compatibility—supports Pt100, Pt1000, Type K, Type T, and other industry-standard analog or digital temperature sensors via modular interface
- Backlit LCD display with hold function, min/max/avg tracking, and °C/°F unit selection
- Battery life exceeding 1,000 hours; powered by standard AAA batteries with low-battery indicator
- Compliant with RoHS and REACH directives; CE-marked for EMC and safety (EN 61326-1, EN 61000-6-3)
Sample Compatibility & Compliance
The thermometer is designed for non-invasive surface, immersion, air, and gas temperature measurements across diverse sample types—including aqueous solutions, cryogenic liquids, pharmaceutical vials, incubators, cold chain packaging, and HVAC ducts. It meets critical regulatory expectations for GxP environments: full alignment with FDA 21 CFR Part 11 (when used with Traceable software for data logging), EU Annex 11, and WHO TRS 961 guidelines for temperature monitoring in storage and distribution. All calibration documentation satisfies audit requirements for ISO 13485, ISO 9001, and USP Analytical Instrument Qualification. The device itself requires no user recalibration—only periodic verification against certified references per internal SOPs.
Software & Data Management
When paired with TraceableLink™ desktop software (sold separately), the thermometer integrates into a broader environmental monitoring ecosystem supporting data export in CSV, PDF, and XML formats. Software features include automated calibration reminder alerts, electronic signature support, audit trail generation (with timestamped user actions and parameter changes), and configurable alarm thresholds. For regulated users, the software package supports 21 CFR Part 11 compliance—including role-based access control, biometric or token-based authentication options, and immutable record retention. Raw measurement logs retain metadata such as probe ID, operator ID, location tag, and environmental conditions at time of reading.
Applications
- Pharmaceutical cold chain validation—monitoring temperature excursions during transport, warehouse storage, and stability chambers
- Biological sample integrity assurance—verifying cryo-storage conditions in liquid nitrogen dewars (−196 °C) and ultra-low freezers (−80 °C)
- Calibration lab support—serving as a transfer standard for verifying thermocouple calibrators, dry blocks, and reference baths
- Food safety HACCP monitoring—documenting critical control points in refrigeration units, ovens, and blast chillers
- Academic and research labs—supporting reproducible thermal profiling in materials science, enzymology, and reaction kinetics experiments
- Medical device manufacturing—complying with IEC 60601-1 thermal safety testing protocols
FAQ
Is the calibration certificate issued by an ISO/IEC 17025-accredited laboratory?
Yes—the certificate is provided by a laboratory accredited to ISO/IEC 17025:2017 for temperature calibration, with uncertainty statements reported at k=2 coverage factor.
Can this thermometer be used for sterile or aseptic applications?
The probe housing is autoclavable up to 121 °C for 20 minutes (validated per ISO 17665); however, the main unit is not sterilizable and must remain outside controlled zones.
Does the device support GLP-compliant data archiving?
When used with TraceableLink™ software and configured with enabled audit trail and electronic signatures, it fulfills core GLP data integrity requirements per OECD Principles of GLP.
What is the recommended recalibration interval?
Annual recalibration is advised for GxP use; for non-regulated applications, verification against a known reference every 6 months is sufficient.
Is firmware upgrade capability available?
Firmware updates are delivered via TraceableLink™ software and require connection through USB-to-serial adapter (included with software bundle).
