Durable pH Probe for Harsh Applications

These rugged pH probes are made for the harsh conditions found in chemical production. They are durable pH sensors that perform at the high pressures and high temperatures associated with chemical manufacturing. Hazardous area pH probes within this category are Ex-certified for use in processes in Ex-classified zones. For chemical processes were low maintenance and high reliability are required, these durable pH probes provide quality pH measurements.

The in-line, industrial pH probes in this family offer solid polymer electrolyte reference systems that allow direct electrolyte contact to the process media via an open junction. This junction nearly eliminates the pH sensor from clogging in viscous applications. This makes these durable pH probes well suited to avoiding diaphragm fouling in applications with sticky media, high particle content and sulfide-bearing solutions.

Glass pH sensors are at risk of breaking in harsh industrial environments. Durable pH sensors in this family are designed to withstand damage. These rugged pH probes offer options such as a titanium shaft to protect against everyday bumps and breaks, in a standard 12 mm electrode design. METTLER TOLEDO also offers industrial pH probe models with polymer PPS and PVDF bodies to protect from mechanical damage and serve as the sensors' built-in housing.

Ensure safe measurement with Intelligent Sensor Management (ISM®) digital technology on a hazardous area pH probe. The Adaptive Calibration Timer function tells you (in days) when you will next need to calibrate your pH sensor, reducing the need to access pH sensors in hazardous areas. With Plug and Measure technology, you can calibrate your rugged pH sensor in a safe environment and then bring it to the measurement point, reducing exposure and time spent in hazardous areas.
