Metler Toledo iSense Asset Management Software

Overview

iSense Asset Management Software is a dedicated desktop application developed by METTLER TOLEDO to support Intelligent Sensor Management (ISM®) technology in industrial process analytics. Designed explicitly for pH, dissolved oxygen (DO), conductivity, and ORP sensors equipped with ISM® digital interfaces, iSense enables lab and plant personnel to monitor, validate, and manage sensor lifecycle data independently of transmitter hardware. The software operates on the principle of embedded sensor intelligence: each ISM® sensor contains an integrated memory chip storing calibration history, usage time, temperature exposure, cleaning cycles, and diagnostic metrics such as asymmetry potential and reference impedance. iSense reads this data via USB connection—bypassing traditional analog signal paths—and translates it into actionable operational insights. This architecture eliminates manual recordkeeping, reduces human error in sensor qualification, and supports continuous process verification under regulated manufacturing environments including pharmaceutical, biotechnology, food & beverage, and water treatment.

Key Features

• Real-time Electrode Health Dashboard: Visualizes key performance indicators—including slope deviation, zero point drift, response time, and junction resistance—for each connected ISM® sensor. Threshold-based color coding (green/yellow/red) enables immediate go/no-go decisions without requiring transmitter output or offline lab verification.
• Offline Calibration Management: Allows full calibration sequence execution—including buffer selection, temperature compensation, and multi-point calibration—directly from a laboratory PC prior to field deployment. Calibrations are digitally signed and timestamped, ensuring traceability and reproducibility.
• FDA 21 CFR Part 11-Compliant Audit Trail: Automatically logs every user action (e.g., calibration initiation, parameter modification, report generation) with immutable timestamps, operator ID, and reason-for-change fields. All records are stored in encrypted format within the local SQL database.
• Predictive Maintenance Analytics: Aggregates historical usage patterns across fleets of sensors to identify statistically significant deviations—such as accelerated reference electrolyte depletion or glass membrane fatigue—enabling proactive replacement scheduling rather than reactive failure response.
• Centralized Fleet Inventory Control: Maintains a master registry of all registered ISM® sensors, including serial numbers, installation dates, location tags, and current status (in-use / in-stock / retired). Supports bulk import/export via CSV and hierarchical grouping by production line or facility.

Sample Compatibility & Compliance

iSense is compatible exclusively with METTLER TOLEDO ISM®-enabled sensors, including InPro 3250/3300 pH electrodes, InPro 6950 DO probes, and InPro 7250 conductivity cells. It does not support legacy analog sensors or third-party digital transducers. The software complies with international quality system standards including ISO 9001:2015 (clause 8.5.1 on control of production and service provision), ISO 13485:2016 (for medical device manufacturers), and EU Annex 11 (Computerized Systems). Its electronic record and signature functionality satisfies FDA 21 CFR Part 11 Subpart B requirements for closed systems, including role-based access control, electronic signatures with biometric or two-factor authentication options, and periodic backup validation protocols.

Software & Data Management

Built on Microsoft .NET Framework and leveraging a local Microsoft SQL Server Express instance, iSense provides structured storage for sensor metadata, calibration events, diagnostic snapshots, and user audit logs. Data retention policies are configurable per site; default settings enforce minimum 10-year archival for regulated applications. Reports—including Calibration Certificates, Sensor Fitness Assessments, and Trend Analysis Summaries—are exportable in PDF (with embedded digital signatures) or CSV (for integration with LIMS or MES platforms). Version 3.2 and later include RESTful API endpoints for programmatic query access, enabling automated synchronization with enterprise asset management (EAM) systems such as SAP PM or IBM Maximo.

Applications

iSense is deployed in environments where sensor reliability directly impacts product quality, regulatory compliance, or process safety. Typical use cases include: upstream bioreactor pH monitoring in monoclonal antibody manufacturing; inline DO control during vaccine fermentation; final rinse water conductivity verification in sterile pharmaceutical packaging lines; and continuous wastewater pH compliance reporting under EPA NPDES permits. In each scenario, iSense reduces unplanned downtime by up to 37% (based on METTLER TOLEDO internal benchmark studies, 2022–2023) through early detection of sensor degradation and elimination of undocumented manual recalibrations.

FAQ

Does iSense require a METTLER TOLEDO transmitter to function?
No. iSense communicates directly with ISM® sensors via USB and does not depend on any transmitter hardware.
Can calibration data generated in iSense be transferred to a transmitter?
Yes—calibration parameters and certificates can be exported and loaded into compatible METTLER TOLEDO transmitters (e.g., M300, M800, or EasyPlus series) using standard SD card or USB flash drive transfer.
Is cloud connectivity supported?
iSense operates as an on-premise desktop application. Cloud synchronization is not natively available but may be implemented via customer-defined secure VPN tunnels and API integrations.
What operating systems are supported?
Windows 10 (64-bit) and Windows 11 (64-bit); Windows Server 2016/2019/2022 with desktop experience enabled.
How is software validation handled for GxP environments?
METTLER TOLEDO provides a validated installation package (IQ/OQ documentation included), along with a Site Acceptance Test (SAT) protocol template and change control guidance aligned with ASTM E5087 and GAMP 5 principles.
