WTW MultiLine® 3400 Series
IDS Meters

These new multi-parameter systems have IDS (Intelligent, Digital Sensors) sensors for pH, dissolved oxygen and conductivity measurement.

The signal processing is completely located in the sensor, and the measuring signal is transmitted to the meter without interference in a clearly identifiable manner via thin, high strength cables. A wide range of sensors are available for virtually every application.

There are 3 models; with one, two or three universal channels that measure every parameter either sequentially or simultaneously. Every model possesses a brilliant color graphic display, two USB interfaces (USB-A and Mini- USB), and rechargeable batteries that can be charged directly in the device.

  • Intelligent sensors store an ID
  • Digital processing and data transfer of sensor measurement
  • Brilliant high resolution TFT color display
  • Simultaneous display of one, two or three parameters
  • Optical support of important maintenance and measuring function
  • Field proven housing with rubber boot (set), waterproof to IP-67
  • Robust and waterproof keypad
  • Error-free operation, even when wearing gloves
  • Waterproof quick-lock sensor connection
  • Datalogger for GLP compliant data
  • Data transfer directly to USB stick or selected printers
  • Mini USB data transfer to PC or for firmware update
