Summary
M300 4-wire Transmitter
The M300 series transmitters are versatile, user-friendly devices for pH/ORP, dissolved oxygen, conductivity/resistivity, and ozone measurements. They offer high measurement performance and ergonomic design with a high-contrast touchscreen and a harmonized menu structure for intuitive operation. Online diagnostics aid in scheduling sensor maintenance and calibration, especially for sensors with Intelligent Sensor Management (ISM®) technology. Configuration can be managed via PC or USB stick using the Transmitter Configuration Tool (TCT), and the USB interface also supports data logging.
Key Features
- Multi-parameter capability: Supports pH/ORP, conductivity, dissolved oxygen, and ozone.
- Flexible sensor input: Mixed-mode input for analog or digital ISM sensors.
- Model variations: Available in Process or Water versions, 1- or 2-channel configurations, and ¼ DIN or ½ DIN sizes.
- Intuitive User Interface: Brilliant 4" TFT touchscreen with an intuitive GUI and 10 selectable languages.
- Fast Startup: Features Plug and Measure functionality and direct connection of pre-calibrated sensors with iSense for quick and error-free commissioning.
- Predictive Maintenance: Advanced ISM functionality (e.g., DLI, ACT, TTM) and iMonitor provide predictive maintenance insights to prevent unplanned shutdowns.
