Chemical & Analytical Calibration
pH and conductivity calibration against standard buffers and solutions, on our ANAB ISO/IEC 17025 scope at the Vista lab.
Accredited Scope of Calibration
Our chemical and analytical calibration scope ensures accurate environmental monitoring, process control, and laboratory measurements for pH, conductivity, dissolved gases, and gas composition.
ISO/IEC 17025 Accredited — ANAB AC-1736
Techmaster Electronics is accredited by ANAB (ANSI National Accreditation Board) under ISO/IEC 17025:2017 for calibration services. The table shows what this discipline covers on that scope and at which laboratory. Measurement uncertainties for every range are in the published scope document.
| Parameter | On scope | Accredited at |
|---|---|---|
| pH, by comparison to buffer standards | 4.01, 7.00 and 10.00 pH | Vista |
| Conductivity, by comparison to standard solutions | 100 to 10,000 µS/cm | Vista |
Other chemical and analytical instruments, such as gas analyzers and dissolved oxygen meters, are not on the scope. Ask us before sending them.
Instruments We Calibrate
We calibrate a wide range of chemical & analytical calibration instruments. Every calibration includes a detailed certificate with measurement data, traceability information, and as-found / as-left values.
pH Meters & Electrodes
Conductivity Meters
Dissolved Oxygen Meters
Turbidity Meters
Gas Analyzers & Detectors
Flow Meters (Mass, Volumetric)
Refractometers
Titrators
Chemical instruments we calibrate most
The chemical instruments and standards we calibrate most often in the last ten years:
| Instrument or standard | Units calibrated (10 years) |
|---|---|
| pH Meter | 49 |
| Conductivity Meter | 44 |
| Conductivity Standard Solution | 33 |
| Conductivity Standard | 16 |
| Ph/Conductivity Meter | 10 |
What usually drifts
- pH electrodes age and slow down, so they drift faster than the meter they plug into.
- Conductivity cells foul, which changes their cell constant.
- Standard solutions expire and absorb carbon dioxide once opened, which shifts low-conductivity readings.
Frequently asked questions
Is pH meter calibration accredited?
Yes, at our Vista lab, by comparison to pH 4.01, 7.00 and 10.00 buffer standards on our ANAB scope.
Do you calibrate conductivity meters?
Yes, at Vista, by comparison to standard solutions from 100 to 10,000 µS/cm on our ANAB scope.
Do you calibrate gas analyzers or dissolved oxygen meters?
They are not on our ANAB scope. Ask us before sending one, and we tell you whether we can calibrate it with a NIST-traceable certificate.
