Use to calibrate any HOBI Labs backscattering sensor (HydroScat Family)
Calibrate in your lab or in the field
Uses Spectralon™ calibration target (available separately), not special fluids or particles
HydroSoft software, free with HOBI instruments, guides you through the procedure, does all calculations, and loads results into the instrument
Description
Transparent acrylic tank; stainless steel threaded rods raise and lower plastic target platform by precise increments
33 x 33 cm (13"), 38 cm (14.8") tall.
Procedure
See the HydroScat Family pages for an introduction to backscattering optics and calibration; for full details of the procedure, see the calibration manual.
The tank is filled with water (preferably distilled or deionized).
A wetted Spectralon™ target is placed on the platform.
The instrument is placed with its face protruding through a hole in the top of the tank, under the surface of the water.
HydroSoft instructs the user on when to raise and lower the platform.
Calibration results may be stored in a file, and/or within the instrument itself.
