InLab Expert Pro-DES pH Sensors
Durable Digital pH Sensors for Clog-Free Weighing & Testing
The Mettler Toledo InLab Expert Pro-DES is a high-performance, digital "3-in-1" pH sensor engineered for durability in demanding laboratory and field environments. Its defining feature is the unbreakable PEEK shaft, which provides superior chemical resistance and physical protection compared to traditional glass probes. By utilizing a solid XEROLYT® polymer electrolyte and an open junction design, the sensor effectively eliminates the risk of clogging, making it the ideal choice for testing "dirty" samples such as wastewater, emulsions, suspensions, and protein-rich food products.
Beyond its physical toughness, the "DES" series integrates Intelligent Sensor Management (ISM) and digital diagnostics to ensure high data integrity. This technology allows the sensor to store calibration data and provide a "health indicator" that monitors the probe's condition in real-time. With its built-in temperature probe for automatic compensation and an ARGENTHAL™ reference system that prevents sulfide contamination, this sensor offers a low-maintenance, reliable solution for professional users who require precise pH measurements across a wide temperature range of 0°C to 100°C.
