  • Page 4: General Information

    We are glad that you have chosen to purchase our VIPER photospectrometer. VIPER is a submersible VIS process spectrophotometer, that is designed for use in industry and science. It may only be used for measuring aqueous solutions, e.g. process wastewater, river water, groundwater and seawater in a temperature range from 2 to 40 °C.

  • 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 cord is not run near hot surfaces. • If the sensor cable is damaged, it must be replaced with an original part by the customer support of TriOS Mess- und Datentechnik GmbH.

  • Page 7: Intended Use

    General Information 1.5 Intended use The intended use of VIPER consists solely in recording absorbance spectra in the visible range and carrying out photometric measurements at specific wavelengths as described in this manual. In this respect, VIPER is a submersible sensor which can be submerged or used with a flow cell. Observe the technical specifications of the accessories.

  • Page 8: Introduction

    VIPER measures color at 410 nm as well as SAC 436, SAC 525 and SAC 620 direct in the medium. A filtration of the water is not necessary because the absorbance at a wavelength of 720 nm is used for turbidity correction.

    413 nm. VIPER measures color at 413 nm directly in the medium. A filtration of the water is not necessary because the absorbance at a wavelength of 720 nm is used for the turbidity correction.

  • Page 10: Measurement Principle And Design

    For the optimal use of the sensor, it is recommended to become familiar with the idea and theory underlying the device, as well as with its assembly procedure. VIPER consists of four parts: a defined light source, a lens system, the optical path through the medium, and a spectrometer.

  • Page 11: Spectra Calculation

    The SAC at the specific wavelength (SAC ) is calculated as shown in Equation 3. In this equation d is the optical path length in millimeter [mm]. For VIPER, optical path lengths of 50 mm, 100 mm, 150 mm and 250 mm are available.

  • Page 12: Temperature Correction

    2.4.3 Temperature Correction The light intensity of LEDs often varies with temperature. Therefore, a temperature correction factor is deter- mined for each wavelength of the VIPER spectrum and used for the spectrum calculation. 2.5 Parameter and Measuring Ranges The following table provides an overview of the measurement ranges of the detectable parameters in depend- ence on the path length.

  • Page 13: Browser

    Introduction 2.6 Browser VIPER is equipped with a web interface for sensor configuration and calibration. To access the web interface, you need a G2 InterfaceBox, an Ethernet cable and an Ethernet-enabled device with a web browser, e.g. a notebook / laptop.
