Service Overview
Soft Tech Serv delivers ISO/IEC 17025-accredited, NIST-traceable thermal calibration and validation for the temperature- and humidity-controlled equipment your samples depend on. From ultra-low freezers to incubators, ovens, and cold rooms, we verify that your units hold the conditions your protocols require — and we document it to the standard FDA and GMP auditors expect.
What we calibrate and validate
We service ultra-low temperature (ULT) freezers and refrigeration units, custom cold rooms, incubators and ovens, chillers and micro baths, heating blocks, and humidity chambers, along with the sensors behind them: thermometers, thermocouples, and resistance thermometers (RTD probes).
Calibration vs. validation
Calibration verifies the accuracy of individual temperature or humidity sensors against NIST-traceable references. Validation goes further — mapping temperature distribution throughout a chamber under loaded and unloaded conditions, checking recovery after door openings, and confirming alarm function, typically documented as Installation, Operational, and Performance Qualification (IQ/OQ/PQ). Many regulated environments require both.
Accredited, traceable method
Calibrations use references traceable to NIST and record as-found and as-left performance with the associated measurement uncertainty. Mapping studies place calibrated sensors throughout the chamber to characterize uniformity and stability over time.
Every service concludes with a detailed ISO 17025 calibration certificate documenting the reference standards used, environmental conditions, measured results against specified tolerances, NIST traceability, and a clear pass/fail determination — the documentation your quality system needs for GxP, GMP, and FDA audits.
Why it matters
Out-of-tolerance storage can compromise reagents, samples, and finished product and trigger costly deviations. Routine sensor calibration and periodic mapping detect drift early, protect product integrity, and provide the documented evidence required for 21 CFR Part 11, GMP, and FDA inspections.
Flexible service delivery
Chamber mapping and validation are performed on-site to capture real operating conditions, while sensor calibration can be completed on-site or in our laboratory — whichever minimizes your downtime.
