Mettler Toledo InLab Expert Pro-ISM

The InLab Expert Pro-ISM pH Sensor Probe is a high-performance, combination pH sensor designed for precise and versatile pH measurements across aqueous solutions, general lab samples, and industrial liquids. Built with Intelligent Sensor Management (ISM) technology, this sensor automatically stores calibration data and transfers its history to compatible meters for seamless plug-and-measure operation.

Featuring a durable PEEK shaft material and a maintenance-free solid polymer reference system (Xerolyt Extra), it offers excellent chemical and mechanical resistance without the need for electrolyte refilling. Equipped with an integrated NTC 30kΩ temperature sensor for Automatic Temperature Compensation (ATC), a standard BNC connector for pH, and an RCA (Cinch) connector for temperature, this probe covers a wide measuring range from pH 0 to 14 at temperatures up to 100°C.
