Abstract

Embodiments provide a handheld fluorometer and method of determining a concentration of a product within a sample. In some cases the handheld fluorometer includes an immersible sensor head that measures a fluorescence of the product and a controller that calculates the concentration of product. In some cases the handheld fluorometer includes a handheld controller module, an immersible sensor head connected to the controller module, a sample cup for containing a water sample, and a fastener that removably fastens the sample cup about the immersible sensor head. In some cases the sensor head is angled with respect to the controller module and the fluorometer provides a substantially stable base. The sample cup can be removed to acquire a sample of water containing the product and then refastened about the sensor head for determining the concentration.

Description

technical field [0001] Embodiments of the invention generally relate to optical measurement devices for testing liquid samples, and more particularly, to fluorometric sensors and fluorometers for determining and monitoring the concentration of one or more substances in a liquid sample. Background technique [0002] In cleaning and antimicrobial operations, commercial users (eg, restaurants, hotels, food and beverage factories, grocery stores, etc.) rely on the concentration of the cleaning or antimicrobial product in order for the product to work effectively. Failure of effective cleaning and antimicrobial products (due to concentration issues) can lead to commercial users feeling that the product is of low quality. Ultimately, consumers will also feel that business users provide inferior service. In addition, commercial users may be investigated and / or sanctioned by government surveillance and health authorities. Therefore, there is a need for a system that can determine ...
