  • Multiple instruments systems - use up to 7 instruments with a single PC 
  • Minimum footprint

 

Witrox 4 is a four-channel oxygen instrument for use with fiber optic mini sensors (optodes). It has a build-in Bluetooth transmitter for wireless PC communication, and includes a high accuracy temperature sensor and software for compensation of oxygen data to changes in temperature, salinity or barometric pressure in real-time.

We developed Witrox 4 for the most challenging environments and applications. The wireless Bluetooth 2.0 communication allows you to keep that vulnerable PC/Notebook at a distance avoiding hazards like water or blood. Also problems associated with USB and serial communication are avoided, and the rugged compact design offers excellent protection and take up minimum bench space. 
The instrument comes with easy-to-use software for Windows, and a 4-wire Pt1000 temperature sensor (Class B 1/3 DIN) with +/- 0.15 °C accuracy for 5-digits real-time compensation of oxygen data.

A PC computer with Bluetooth 2.0 or higher (build-in or dongle) is required for operation.

How does it work?

The instrument LEDs emit blue-green light that excites the oxygen mini sensor (optode) to emit fluorescence. If the oxygen sensitive dye encounters an oxygen molecule, the excess energy is transferred to the oxygen molecule in a non-radiative transfer, decreasing or quenching the fluorescence signal. The degree of quenching correlates to the partial pressure of oxygen inside the dye matrix, which is in dynamic equilibrium with oxygen in the sample. The decay time measurement is internally referenced.

Included with the Witrox 4

Sensors

4
Flow-through oxygen cell (10mm)
Flow Through Oxygen Cell OX11220

Features

  • Easy to handle
  • Very robust sensor
  • Excellent long-term stability
  • No self-consumption of oxygen
  • Signal independent on flow velocity
  • Insensible towards electrical interferences
  • Measures oxygen in liquids as well as in gas phase

 

This flow-through oxygen mini sensor requires a fiber cable with bare tip for use with Witrox 1 and Witrox 4 instruments. The re-usable (non-disposable) oxygen sensor has excellent long-term stability. Clean it with ethanol or even ETO, recalibrate, and use it again and again.
