  • Page 8: Safety Regulations

    Manual EDM 180 Important hints for the customer 2.1 Safety regulations The manufacturer declines any direct or indirect liability if the operator opens the instrument or manipulates the instrument! This instrument is built and tested in accordance with EN-61010 (DIN VDE 0411 T1) to assure proper protection of the electronic material and measurement function of the instruments.

  • Page 9: Electric Safety

    Caution! Optical laser class 3 B inside! The instrument may only be opened by GRIMM trained service personnel. During the opening of the laser unit, especially the measuring chamber, a laser radiation of the class 3 B can be released. The direct look into the laser beam or a reflexion can lead to damage of the eyes even at a short exposure time.
  • Page 10 Manual EDM 180 All stickers shown are on the bottom of the instrument and warn the operator for laser light radiation in case the covers of the instrument have been dismounted! Laser class 1 in closed state of the measurement unit! Laser of class 1 are not dangerous and safe for eyes even in case of malfunction due to manipulation or usage of optical additives (e.g.
  • Page 11 Manual EDM 180 2.5 Extreme ambient conditions Altitude correction The pressure altitude formula describes the vertical distribution of the (gaseous) particles in the Earth´s atmosphere, means the change of the barometric pressure related to height. This is also called the vertical pressure gradient.
  • Page 12 The external probe head heating model 180-DF is an accessory for the Enviro product line of the company GRIMM (165, 365, 180, 190, 565). It keeps the probe head ice free when having frost and thus enables failure-free measurements. The heating heats up to a maximum of 10°C.
  • Page 13 EDM 180 2.6 Test kit 186 The EDM Test kit model Nr. 186 is an accessory part for the Enviro product line of the company Grimm (165, 365, 180, 190, 565). It controls the correct installation and function of the systems.

  • Page 14: Sample Head

    Manual EDM 180 EDM 180 3.1 Introduction The measuring device for airborne dust of the series 180 is a stationary instrument which has been designed for the continuous measurement of airborne dust and its particle size distribution. The measured values will be output as mass concentration in the unit μg/m³ and distinguished according the fractions PM10, PM2.5, and PM1.
  • Page 15 Figure 2: Measuring principle All Grimm laser aerosol spectrometers and dust monitors use a laser diode as light source. The wavelength is for model 365 in visible range at 655 nm. The laser diode can be operated in a so- called Multiplex Mode, i.e.
  • Page 16 Manual EDM 180 The count rate results from the number of particles divided by volume flow rate. The particle size is proportional to the intensity of the detected scattering light signal whereas the scattering light intensity is also being influenced by the particles refractive index, particle shape, and orientation of the particle within the measuring volume.
  • Page 17 PSL samples and so validates the particle size measurement for this standard material. The first Grimm mother device, sort of “grandmother”, moreover was being compared to a reference device, viz. the laser aerosol spectrometer model LAS-X by PMS, Boulder, Colorado. By this procedure we ensure the correct particle size measurement in the specified channel, e.g.
  • Page 18 EDM 180 Grimm Calibration procedure The calibration between a candidate and the mother unit is done by use of a "Grimm Calibration Tower" that isfully computer-controlled and -automated and poly disperse dolomite dust as a standard aerosol. Why dolomite dust? Dolomite dust is cheap, anoxic, not hygroscopic, poly disperse and very stable during storage.
  • Page 19 After the tower calibration, a further comparison at indoor conditions is done. To illustrate the described procedure, the following two screenshots, so called "ramp" from the Grimm calibration software CalSoft, show two examples of a measured particle number concentration of a candidate compared to a reference unit before and after a calibration.
  • Page 20 Manual EDM 180 Figure 3: After calibration: Simultaneously measured particle number concentration for all 31 size channels of the candidate (red) and the mother unit (blue) vs. time At all enviro products (107, 180, 365) a continuous test of the complete system follows with an own sample probe and housing.
