Mercury Thermometer Calibration Services
Legacy instruments with reference-grade reputations — maintained honestly or retired knowingly.
ACS Calibration delivers NIST-traceable, audit-ready mercury thermometer 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.
Respect the Legacy, Verify the Column
Mercury-in-glass thermometers still anchor some methods and incubator monitoring because their stability is genuinely excellent — but only while the column is continuous and the ice point hasn’t shifted. Aging bulbs and separation events change readings permanently, and regulatory pressure means every remaining mercury unit should be earning its keep.
We calibrate mercury thermometers by comparison under our accredited capability with as-found data per point — and when a unit is due for retirement, we can verify its digital replacement against the same standards so the transition is documented, not hopeful.
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 Mercury Thermometer 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.
