WTW inoLab® Laboratory Multi-parameter Benchtop Meters

Application oriented benchtop sets for multiple parameter monitoring: pH, mV, ISE, saturation, concentration, partial pressure, conductivity, special resistance, salinity, TDS, temperature

Cutting edge technology from WTW for demanding laboratory applications. Two digital inoLab® multi-parameter instruments for IDS sensors for parallel measuring of one identical or varying parameters. Up to three sensors (inoLab® Multi 9430 IDS) can be connected. A large glass shield protects the graphic display and supports the presentation of the measuring values and recognition of important information. The innovative and antibacterial keypad helps to protect against microbiological contamination. The solid zinc die-casting lower case gives the meters a safe standing and also protection from the environment. As a special feature, both models can be upgraded with an additional module for conventional pH measurement.

Measuring stability

  • No errors with the digital signal transmission, calibration data is allocated safely, sensor data is easily transmitted. eliminates errors
  • The intelligent sensor evaluation (QSC) gives a status about the condition of the sensor and increases the operational reliability.
  • The CMC function visualizes the ideal measuring range and supports correct measuring.
  • Visual display of channels for allocation of sensors and parameters

All benchtop meters are available in application oriented sets including sensors and accessories.
