Abstract: An instrument determines a concentration of bacteria in a plurality of fluid samples, and comprises a housing, a rotatable platform, a plurality of fluid containers, a light source, a sensor, and a motor. The rotatable platform is within the housing. The fluid containers are located on the rotatable platform. Each fluid container holds a corresponding one of the plurality of fluid samples, and has an input window and an output window. The light source provides an input beam for transmission into the input windows of the fluid containers and through the corresponding fluid samples. The input beam creates a forward-scatter signal associated with the concentration of bacteria. The motor rotates the rotatable platform so that the input beam sequentially passes through each fluid sample. A sensor within the housing detects the forward-scatter signal exiting from the output window associated with the fluid sample receiving the input beam.

Abstract: A method and an apparatus are presented for monitoring a concentration of a specific halogen in a body of water such as a spa or bathing unit for example. The apparatus comprises a housing in which is positioned an optical absorption analyzer for making first and second measurement of transmission of ultraviolet light from a light source emitting light at a specific wavelength. The second and first measurements are taken respectively before and after the ultraviolet light has travelled through a sample of water and are used to derive a concentration of the specific halogen. The derived concentration may then be communicated to a user using a display device and/or may be used to control operational components of a bathing unit for adjusting the concentration of halogen in the water. In some practical implementations, the apparatus may be embodied as a standalone device, which may be configured to float on the water of the bathing unit or, alternatively, may be configured for being installed in-line in a water circulation path of the bathing input by connecting the housing to circulation piping.

Abstract: Systems and methods of the present disclosure are directed to detecting species within a fluid using a multi-pass absorption cell and a spectrometer. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. The system also includes an electronic unit configured to receive and process spectral data from the spectrometer. In some implementations, the electronic unit communicates with at least one computational unit over a communication interface to send a portion of the spectral data for processing. The electronic unit may also receive processed data from the computational unit.
