Apera pH Meter Calibration

Applied Technical Services (ATS) strives to meet your equipment needs with Apera pH meter calibration and certification from our experts. Apera manufactures benchtop pH meters and portable sensors that measure pH in water, soil, and paints, as well as high-temperature solutions for laboratory research, field measurements, and quality control. ATS calibrates at multiple values across the meter’s range to ensure continued accuracy of alkalinity and acidity measurements.

Schedule calibration with a qualified ATS lab to comply with regulations for your industry. Apera pH meters require frequent recalibration, as each measurement exposes their sensitive probes to potential contaminants. Over time, these contaminants can harden into a thin layer of scaling or corrode the surface of the probe, degrading the meter’s accuracy when comparing hydrogen ions in a solution. In high-precision applications, this drift can severely impact quality control and reliability.
ISO 17025 pH Meter Calibrations
The ATS calibration lab is ISO 17025 accredited in chemical, dimensional, electrical, flow, and mechanical calibrations. An expert assigned to your device will follow documented and controlled calibration procedures from NAVAIR, ASTM, ISO, and other international standards organizations as appropriate to the service requested.

Our experts compare pH meters with standard pH buffer solutions. We operate a temperature- and humidity-controlled lab to restore accuracies within +/- 0.2 pH. If a pH meter is not within specification, a technician can adjust the device until readings comply with Apera’s recommendations and the client’s tolerances.
