TTurb probe

Digital TTurb sensor

The TTurb probe is a digital sensor for optical turbidity measurement using the 90 ° scattered infrared light method. Depending on the version of the sensor, it can be used in potable water up to 100 FNU as well as in raw water, waste water and process water up to 1000 FNU. The TTurb probe is available with different cable lengths (10 m or 2 m).

The Tturb can be used directly immersed in the environment, but also mounted as a bypass thanks to its adapted passage cell. In addition, it is possible to obtain the TturbCAL with the sensor, which is a standard adapted specifically to each probe for an accurate functional test without reagent.

The operating status is indicated by an LED in the upper part of the sensor, allowing easy and visual identification of the correct functioning of the sensor.

Available in 3 versions:

TTurb 100

TTurb 400

TTurb 1000

Measurement principle

The Tturb digital probe works with TriBox Mini and TriBox 3 transmitters.
Once the probe is connected, the transmitter powers the sensor, receives and uses the data. The measurements are displayed on the screen, they are recorded and can be converted to the 4-20 mA analog signal.
Interface on web browser accessible by Wifi or Ethernet.
