Analytical Technology’s pH Monitor Achieves Prestigious MCERTS Certification

Specialist electrochemical sensor manufacturer Analytical Technology announces that it has been awarded an MCERTS product conformity certificate for its versatile Q45P pH monitor. MCERTS is the UK Environment Agency‘s monitoring certification scheme established to deliver quality environmental measurements. The certification of the Q45P is a significant achievement for Analytical Technology as it provides customers with confidence in the system’s emission monitoring capabilities for the protection of the environment and human health.

Businesses that release emissions to air, land and water are required to comply with strict regulations and obtain permission to operate from the UK Environment Agency. This permission requires businesses to either monitor their emissions on a continuous basis or at times defined in their permit, known as spot tests or periodic monitoring. In both cases, they must meet the MCERTS quality requirements. MCERTS is based on international standards and provides for the product certification of instruments, the competency certification of personnel and the accreditation of laboratories. The MCERTS scheme is designed to give customers a range of tested equipment to choose from for certain key wastewater quality parameters.

Analytical Technology has achieved MCERTS certification for its Q45P Auto-Clean pH monitor, which is designed for use in all industrial and municipal applications. The differential pH sensors utilise a sealed glass reference system providing protection from chemical poisons that destroy traditional pH sensors. A large electrolyte volume, dual junction saltbridge is used to maximise the in-service time of the sensors and minimise contamination of the reference solution. The replaceable saltbridge also allows for easy and inexpensive sensor regeneration.

Dr Michael Strahand, General Manager (Europe) at Analytical Technology, comments: “We are delighted to have been granted the prestigious MCERTS certification for our Q45P monitor. This achievement comes as a result of hard work by our staff members and reinforces our commitment to investing in the development of effective and compliant analytical sensing systems. With the MCERTS-certified Q45P monitor, customers in the

environmental and water industries can rely on a highly dependable system that offers maximum up-time and facilitates regulatory compliance.”

The integrated Auto-Clean System of the Q45P extends sensor cleaning intervals on pH sensors that are mounted in applications containing high levels of solids contamination. Generating high pressure air blasts, the Auto-Clean System automatically removes contaminants from the face of the sensors. Each cleaning cycle lasts approximately two minutes, during which the monitor outputs are placed in a ‘hold’ condition to prevent false

readings or alarms. The concentration of solids in the process determines the cleaning frequency of the system, which can vary from as often as once every two hours to as little as once a day on an application basis.
