What is Physical-Chemical calibration?
Physical-chemical calibration determines the error of instruments measuring physico-chemical quantities: pH, electrical conductivity, turbidity, density, refractive index and more. Techmaster’s ISO/IEC 17025:2017 lab uses traceable certified reference materials (CRMs).
In labs, water treatment, food & beverage and pharma, physico-chemical parameters determine product quality and the reliability of test results. Faulty instruments can lead to wrong conclusions and compliance risk.
Techmaster calibrates physical-chemical instruments using traceable reference solutions and certified reference materials (CRMs), ensuring accurate, ISO/IEC 17025-recognized pH, conductivity and turbidity results.
Quantities & parameters we calibrate
Instruments Techmaster calibrates
Typical measurement ranges & CMC
The table below lists typical parameters & measurement ranges for this discipline.
| Parameter / Instrument | Typical measurement range | CMC / Measurement uncertainty |
|---|---|---|
| pH meter | 0 – 14 pH | [Verify against scope] |
| Conductivity | µS/cm – mS/cm | [Verify against scope] |
| Turbidity | 0 – 1000 NTU | [Verify against scope] |
| Density | per instrument range | [Verify against scope] |
| Refractive index | 0 – 95 %Brix | [Verify against scope] |
⚠ Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.
Reference standards & traceability
Physical-chemical instruments are calibrated with traceable reference solutions & certified reference materials (CRMs) (e.g. pH buffers, KCl conductivity standards, formazin turbidity standards), ensuring traceability to the international measurement system.
