Checker photometer for nitrite HR (0-150 ppm) w/ starter kit

Ideal for marine, salt and fresh water aquariums, along with environmental, water quality and wastewater testing. The HI-708 Checker is a simple, accurate, and cost effective way to measure high ranges of nitrite. feature 0 to 150ppm li feature Ideal for aquariums li feature Nitrite Ideal for marine, salt and fresh water aquariums The HI-708 Checker is a simple, accurate, and cost effective way to measure high ranges of nitrite Designed as a more accurate alternative to chemical test kits, the HI 708 provides quick, accurate results in four easy steps (see below). The HI-708 uses an adaptation of the Ferrous Sulphate method. The reaction between nitrite and the reagent causes a greenish/brown tint in the sample. Also ideal for: Water Quality Education Aquariums (marine, salt and fresh water) Wastewater Environmental Features: Small palm-sized design Accurate from ±3 ppm ±5% of reading Dedicated to a single parameter Uses a single AAA battery Auto Power Off after 10 minutes in inactivity Built-in timer for timed reaction readings Order Information: The HI-708 Checker is supplied with: 2 cuvettes and caps reagent starter kit (6 packets of reagent) – re-ordering information HI-708-25 1 X 1.5X AAA battery Instruction manual Aquarium use The checker is useful for initial measurements of nitrite when trying to establish good ammonia/nitrite/nitrate control. Suitable for all types of aquaculture, the ultimate aim is to decrease nitrite levels so that the low range of ultra-range nitrite checker can be used for optimum tank health. Nitrite can lead to tissue damage, illness and death of aquatic life, so regular checks can help aquarists identify rising nitrite levels before fish begin to suffer. Four steps. One click.
