pH is one of the most common measurements and is used in industrial processes, research and development, wastewater treatment, food and beverage processing, agriculture, and more. pH tests the alkalinity of pools and the acidity of foods such as cheese. Because both accuracy and compliance are important for key measurements in research and food safety, keeping your pH meters or testers calibrated is necessary.

Professional pH Calibration

Professional calibration aligns the electronics within the meter and tests the unit according to your manufacturer’s accuracy at standard test points or those you choose. Your calibration certificate is evidence your meter is certified and meets compliance.

Questions? From pH meters to pH testers to pH calibrators, InnoCal can calibrate your instruments. We maintain a full fleet of electronic calibrators, ISO Guide 34-accredited pH and conductivity solutions, and high-accuracy temperature standards.

Measuring pH tells you how acidic or basic (alkaline) your solution is. Biochemists and food industry scientists measure the pH of food, dairy, and beverage products for quality. In industries such as oil refining, textiles, and paper and printing, pH measurement is an integral part of processes that produce the end product. Outside of the lab and the manufacturing plant, monitoring the pH of water and wastewater is essential in environmental control. According to the EPA, “measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater.”

Conductivity tests a solution’s ability to conduct electrical current and serves as a quick and simple indicator of water quality and purity. Conductivity measures the ionic content in a solution and is assessed for pharmaceutical waters, boiler water, fermentation, and public water supplies. Conductivity can also indicate how much pollution is in rainwater and rivers.

Testing the Tools: Are Your Readings Correct?

Described by Lab Manager as a mainstay of laboratories, pH meters commonly test the pH of solutions while conductivity meters, resistivity meters, and sometimes multiparameter meters typically measure conductivity. If you’re losing confidence in your pH or conductivity readings—and it’s not an issue with the electrodes or environmental factors such as static electricity—it may be time for meter calibration.

At an ISO17025-accredited calibration lab, your meter will be tested to the manufacturer’s accuracy at standard test points or to those of your choosing. Electronic calibrators, ISO Guide 34-accredited pH and conductivity solutions, and high-accuracy temperature standards are used to ensure that your meter is restored to full precision, or, in some cases, recommended for replacement.

InnoCal is the only authorized ISO17025-accredited calibration lab for Oakton®, Accumet®, Thermo Scientific, and Orion® pH meters. We maintain a full fleet of electronic calibrators, ISO Guide 34-accredited pH and conductivity solutions and high-accuracy temperature standards.

As Group Leader for Customer Returns, April Buckley is a problem solver and a customer advocate. “I often have to solve problems or help answer questions,” she said. “I look at each question like a puzzle and I love to solve puzzles. I am constantly thinking about how to solve the next one.”

While not technically a metrologist, April’s more than 20 years of experience in satisfying customers serves InnoCal customers well. “We work hard for customers,” she explained. “We’re happy to help in any way we can, whether it is providing a quote, processing a service return, or resolving an issue. Above all else, we think about customers first. “

When she pulls herself away from the phones and the computer screen, April can often be found in front of another screen. “I like to play video games, mainly massively multiplayer online games (MMO’s) such as Guild Wars® 2 and Lord of the Rings Online™ (LOTRO),” she said. This, of course, is only when she is not out walking in the forest preserves with family, friends, and her pooch.

As an InnoCal customer champion for four years, April’s days are filled with navigating calibration and repair orders, phone follow-ups, and creative solutions to meet or exceed customers’ expectations. Yet, she is pleased that her role is people-intensive. “I like that I get to interact with a lot of people,” she said.
