Checker photometer for phosphate ULR 0,00 to 0,90 ppm | S/M

HI774 Details: The HI-774 Ultra Low Range Phosphate Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate from 0.00 to 0.90 ppm. Phosphate is an important parameter to measure in aquaculture and aquariums. Levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI-774 provides quick, accurate results in a few easy steps (see below).  Please download the Safety Datasheet(s) which provide more detail on the reagents before use; click on the link in the “safety data sheets” paragraph below. Features: Easier to use and more accurate than chemical test kits Dedicated to a single parameter Small size, big convenience Ideal for: Aquariums, Environmental, Aquaculture, Water Quality Tips for an accurate measurement It is important that the sample does not contain any debris. Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil and dirt. Wipe it thoroughly with HI-731318 or a lint–free cloth prior to insertion. Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove bubbles by swirling or be gently tapping the cuvette. Do not let the reacted sample stand for too long after reagent is added as accuracy will be affected. After the reading, it is important to immediately discard the sample otherwise the glass might become permanently stained.
