  • Page 5: Health And Safety Information

    Devices that radiate strong electromagnetic waves can influence the measurement data or result in a malfunc- tion of the sensor. Avoid using the following devices in the same room as the TriOS sensor: mobile phones, cordless phones, transmitters/ receivers and other electrical devices that produce electromagnetic waves.

  • Page 6: Warnings

    Make sure that the cable is not run near hot surfaces. • If the sensor cable is damaged, it must be replaced with an original part by TriOS Mess- und Datentechnik GmbH or an authorized TriOS technician.

  • Page 7: Intended Use

    The use of other media can damage the sensor. For the use of the microFlu HC in media other than those specified here, please contact the technical support of TriOS Mess- und Datentechnik GmbH (support@trios.de).

  • Page 8: Introduction

    HC fluorometers are low-cost, submersible miniature fluorometers for highly accurate and selective measurement of polycyclic aromatic hydrocarbons (PAH) and oils. microFlu HC is mainly used to detect leaks. Therefore microFlu HC is perfect for monitoring waters, in which industrial water is discharged or other waters located close to industry.

  • Page 9: Purchased Parts Package

    Filter Lens Photo diodes Essentially, the microFlu HC consists of four parts: a defined light source, a lens system, the optical path, and a detector with equal-light suppression. The arrangement of these parts is represented schematically in the above illustration.

  • Page 10: Fluorescence

    Double-bond electrons are excited more easily, because the p-electrons of the double bond are distributed over both atoms and are therefore not so strongly bound. Molecules with a conjugated double bond are particularly suitable for fluorescence; the electrons are distributed over several atoms and are therefore very easy to excite.

  • Page 13: Interfaces

    3.2.1 Serial interface The microFlu HC provides a line for digital serial communication with a control unit. It is equipped with a con- figurable digital serial interface as RS-485 (also EIA 485). The interface cannot be switched and is already defined when delivered.

    3. Now bring the pressure ring from the cable/connector side onto the microFlu HC. 4. Insert the microFlu HC into the flow cell, making sure that the O-ring does not slip into the FlowCell. 5. Tighten the screw connection (without tools).

  • Page 16: Calibration

    5 Calibration 5.1 Manufacturer calibration All TriOS sensors are delivered calibrated. The calibration factors of the microFlu HC are stored in the sen- sor,meaning all output values are calibrated values. The conversion from the original measurement parameter to the scaled measurement parameter is carried out by means of the following equations.
  • Page 17 A = parameter – offset B = A ∙ Scaling With A as the parameter output that is output by microFlu HC. offset corrected value offset value...
  • Page 18 The offset is also given by the ab- scissa of the straight line (X-axis intersection). For the above example, this means: 90 – 30 scaling factor = 40 – 20 offset = 40 – = 40 – 30 = 10 D01-030en202409 microFlu HC Manual...
  • Page 19 Calibration Measured concentration [µg/L] All TriOS controllers have the ability to set scaling factors and offset values for the measurement parameters. Please refer to the appropriate manual. Customer calibration can be used as a fine adjustment of the sensor for special media and is not intended to replace the manufacturer calibration.
