Resistivity / Conductivity Sensor

UniCond Resistivity / Conductivity Sensor with ISM

The UniCond conductivity sensor from METTLER TOLEDO provides exceptionally wide measurement ranges due to its advanced built-in measuring circuit. The on-board measuring circuit eliminates interference from leadwire resistance and capacitance. Only digital signals go back to the transmitter. Advanced measuring techniques further contribute to superior accuracy over the expanded range. ISM technology features pre-calibration Plug and Measure capabilities for fast, compliant start-up.

InPro 7100i Digital Conductivity Sensor for Buffer and Media Prep

The InPro 7100 digital conductivity sensor is particularly suited for use with single use mixing and buffer storage bags. The fast response time allows quick detection of process changes, leading to better process control. The PEEK shaft material offers high resistivity against aggressive solutions and is particularly suitable in process with frequent CIP / SIP cycles. The InPro 7100 can be used for sterile insertion into bioprocess containers.


What exactly is ISM?

ISM®, a breakthrough technology from METTLER TOLEDO, 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.
