MultiLine® IDS: Multi-parameter measurement redefined
The new MultiLine® handheld devices with their intelligent digital IDS sensors are state-of-the-art systems for mobile multi-parameter measurement. They stand out among their competitors by the fact that the signal processing is completely located in the sensor. The sensor independently logs on with the unit and transmits clearly identifiable data and the current calibration. This prevents data mix-up. The digital signal transmission allows for long cables for all parameters. The unique QSC function for IDS pH sensors makes it possible to evaluate the current sensor status. CMC function for checking the optimum pH measuring range. Large portfolio of IDS-pH, conductivity, and oxygen sensors for almost all types of applications. Watertight, universal Quick-Lock connectors at the unit protect the sensors from loss.
The sturdy, watertight (IP 67) MultiLine® handheld instruments have a high-resolution graphic color display for optimum operation and information. With special silicone membrane keypad for excellent operation comfort, and USB interface for data transfer to USB memory sticks or printers. Economical operation thanks to NIMH rechargeable batteries. Available as portable set complete with sensors and accessories for operation in the field.

Choose between 3 different models:

Multi 3410: One measurement channel for pH, ORP, conductivity and oxygen measurement: For those who need to measure mainly one parameter, but occasionally require a second or third.

Multi 3420: Two measurement channels: For simultaneous parallel measurement with two similar or different sensors and parameters.

Multi 3430: Three measurement channels: For simultaneous parallel measurement with up to three similar or different sensors and parameters.
