pH Calibration Service

our Mission


Our technicians are trained to provide accurate pipette calibrations by implementing ISO 17025 methods and practices. We use high resolution micro balances to allow testing in accordance to the tolerances specified in ISO 8655. We utilize unique techniques, such as standard liquid thermometers and evaporation traps, to ensure the highest level of precision in our field measurements.

Pipette Calibratin Service


Here at Equipment Calibration Services , we provide calibration and validation services for  gauge blocks, micrometers, mass standards, pin gauges and much more.  If your company has equipment or a device that is out off our scope of calibration, we will subcontract to an accredited company.  Equipment Calibration Services is dedicated to providing our clients with outstanding professional services.  Allow us to worry about your calibration so you can focus on what is most important to you.

-Equipment Calibration Services Management

Equipment Calibration Services develops standard operating procedures to adhere to the rigorous requirements of ISO/IEC 17025:2005.  Calibration reports follow these guidelines for pipettes, centrifuges and temperature devices and balance calibration services.  Our management and technical system are audited yearly to ensure we are at the top of the industry and to ensure we are growing properly as a company.

Whether our clients choose on-site or mail-in services, calibration procedures and validation services are performed in accordance with applicable documentation.  With the utilization of state-of-the-art equipment and calibration standards, ECS produces accurate and precise results every time.

We stand by every pipette calibration, balance calibration and temperature calibration service performed. In fact, ECS stands by every calibration procedure, regardless of the service. To show accurate our results are, ECS offers our clients a 6-month warranty on our services.  Our clients can rest easy when we leave their facility.   

pH & Centrifuge

pH meters are calibrated at a minimum of 3 pH values to produce a linear calibration curve  that represents the accuracy and precision of the instrument under test.

With the use of NIST buffer solutions, pH probes are calibrated back to factory recommendations.

Centrifuge calibration is achieved through utilizing NIST traceable tachometers accurate to .01% that are capable of measuring rotational speed of 99,999 RPM. Go to our IQ OQ PQ Page to ensure your centrifuge is installed and operating correctly. 

Temperature Calibration Service
