Robust, waterproof housing Display unit with universal measuring channels to measure pH, redox, conductivity, dissolved oxygen and turbidity All WTW IDS sensors are connectable. IDS sensors convert measurement signals into digital signals and operate accurately and interference-free Automatic recognition of IDS sensors. Sensor ID (sensor name and serial number), calibration data and measurement settings are stored in the sensor head and transferred to the pH meter; this allows operation on different measuring devices without recalibration GLP-supporting documentation: documentation of device and sensor data; user administration via MultiLab ® User Waterproof Mini USB-B interface for data transfer to PC with MultiLab ® Importer Optional accessories (please order separately): Radio equipment for cordless measuring IDS sensors for different parameters Combi hand-held measuring device MultiLine ® Multi 3510 IDS with one measuring channel Perfect entry-level device for digital IDS multi-parameter measurement. Easy-to-read, backlit b/w graphic display Delivery incl. buffer solutions (pH 4 / 7; EC 1413 μS/cm), software, USB cable, carrying case and batteries.
