Refrigerator Mapping & Validation Services
Vaccines and reagents live in the worst corner of the fridge — mapping finds it before an excursion does.
ACS Calibration delivers NIST-traceable, audit-ready refrigerator mapping services, available at the ACS central lab or directly on-site at facilities across the Southeast. Temperature from -196 °C to 420 °C, infrared to 500 °C, and humidity from 30 to 75 %RH are on our accredited scope, so ISO/IEC 17025 accredited certificates are available on request.
Temperature & Humidity Instruments We Calibrate
From cryogenic checks to furnace controllers — if it reads degrees or percent RH, we can almost certainly handle it.
Frequently serviced brands: Traceable (Control Company), Gemini Tinytag, T&D, MadgeTech, Fluke, ThermoWorks, LogTag, and ThermoPro — plus dozens more.
2 to 8, Everywhere, Proven
Pharmacy and laboratory refrigerators hold product in the 2–8 °C window — but compressor cycles, door traffic, and shelf placement create zones that dip toward freezing or drift warm while the display reads perfectly centered. CDC vaccine storage guidance and pharmacy inspections both push toward documented mapping.
We map refrigerators with calibrated loggers across shelves, drawers, and door zones — identifying the worst-case location where your continuous monitor belongs — with a full uniformity report. Pair with logger calibration and walk-in mapping for the whole cold chain.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
Why Companies Choose ACS for Refrigerator Mapping Services
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. Temperature (-196 to 420 °C), infrared (35–500 °C), and humidity (30–75 %RH) are on our ISO/IEC 17025 accredited scope — accredited certificates available whenever your quality system requires them.
4–6 Business Day Typical Turnaround
Keep production moving. Most instruments are typically completed in 4 to 6 business days from arrival, with rush options available when a line is down.
Flexible Logistics
Mail your instruments in, or schedule onsite calibration and we come to your floor — serving Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and beyond.
