Experts in pH measuring technology Experienced, skilled, reliable Endress+Hauser pH measuring systems are in operation anywhere priority is given to reliable

Research and development pay Ranging from non-glass pH sensors to fully automated measuring points, R&D certainly pays off and means we can offer excellent price/performance ratios to our customers. With their twin-chamber reference system or ion traps and gel compositions for tough, chemical applications, our sensors offer maximum protection against contamination and a wider measuring range. They boast a service life many times that of conventional pH/ORP sensors, which translates to a significant reduction in operating costs for pH measuring points. Further examples of new technology include sensors for fermenter applications with a pressurized reference system or sensors for upside-down installation.

Benefits • Long electrode operating times reduce operating costs • Consistently high product quality • Outstanding price/ performance ratio • Excellent manufacturing structure guarantees high product availability

measured values, a high degree of availability and long operating times. With an annual production rate of over 320,000 process sensors, the company is an international market leader. With its accredited calibration laboratory, Endress+Hauser sets a new standard when it comes to ensuring correct measurement results. For our customers, this means they can rely completely on our pH quality buffers.
