Ingold Process Analytics

METTLER TOLEDO Ingold is the leading supplier to end users and system integrators for analytical measurement solutions to monitor and control production processes. Ingold offers innovative analytical sensors for pH, dissolved oxygen, conductivity, turbidity and CO₂ measurements. 

Ingold sensors are trusted globally in the chemical, pharmaceutical, biotech, and food and beverage industries.

Ingold was founded in 1948 by Dr. Werner Ingold, a Swiss chemist and entrepreneur. Ingold is widely considered as the leader in the production of pH sensors. Ingold was acquired by METTLER TOLEDO in 1986 and is part of the Process Analytics division.

Ingold's invention of the single-rod measuring cell, a combination of measurement and reference electrode in one construction unit, in the early 1950s, marked a step towards becoming one of the world's leading companies in the field of pH measurement. METTLER TOLEDO Ingold continues to innovate unique equipment for process analytics and to expand its product portfolio. Another innovation of METTLER TOLEDO Ingold is the Intelligent Sensor Management (ISM) technology. ISM is a breakthrough technology from METTLER TOLEDO, which allows users of process analytical equipment to benefit from accurate diagnostics that predict when sensor maintenance will be required, while also increasing production process safety.

It is a digital technology that incorporates intelligent algorithms into sensors and analyzers. The combination of on-board microprocessors and algorithms that actually learn from process conditions, simplifies sensor and analyzer handling and workflows. ISM delivers a level of performance that analog systems simply cannot provide, including:

Increased accuracy and measurement confidence

With ISM the process parameter value is calculated directly in the sensor, resulting in higher accuracy than analog probes. Moreover, the digital signal is unaffected by plant conditions and is stable over long cable runs, providing you with greater assurance in your processes.

Online sensor diagnostics

ISM sensors continuously check themselves for wear. Inside the probe sophisticated algorithms learn from process variables to calculate when sensor calibration or replacement will be due. The Adaptive Calibration Timer and Dynamic Lifetime Indicator allow you to use your resources more efficiently.

Easy, error-free operation

ISM sensors store their own calibration data. They can be quickly and accurately calibrated away from the process in any suitable location. When they are connected to an ISM transmitter, this data is uploaded and the transmitter configures itself automatically.
