Phosphate LR Checker

HI713 Details:

The HI-713 Phosphate Checker provides an accurate solution for measuring low range phosphate within both marine and freshwater fish tanks. This digital phosphate tester has a single-button operation to measure phosphate in aquariums, providing fast information to allow you to monitor and adjust your water quality.

Hanna’s range of phosphate Checkers includes all required ranges for tank maintenance and care alongside a wide range of other key parameters.

•  0.00 to 2.50 ppm
•  Ideal for coral, salt and fresh water tanks
•  Phosphate

The HI-713 Checker is a fast and accurate method for measuring low range phosphate within all kinds of aquariums, including reef, marine and freshwater fish tanks. This compact digital tester allows you to determine the amount of phosphate in tank water, with a single-button operation and clear, easy-to-read results on an LCD screen in ppm.

The HI-713 electronic tester covers the low range for phosphate testing in aquarium water, from 0.00-2.50 ppm. An included AAA battery is required to power this Checker, and a built-in auto-off feature after 10 minutes inactive preserves battery life for continued testing.

Why measure phosphate?

Phosphate is present in most tanks, and is typically managed using filtering, cleaning and binding chemicals to keep them within an acceptable range. Sources of phosphate include broken down or decaying food and plant matter in addition to pH and kH buffers and waste products from fish. While phosphate is not directly an issue, high levels cause algae blooms that decrease oxygen and may change the pH of the water, indirectly causing harm.

Measuring phosphate regularly is an ideal way to keep this parameter in the lowest range possible. Using a digital Checker is fast and accurate, enabling you to have results as quickly as possible to make the necessary changes to your fish tank to prevent algae growth.

How does the HI-713 work?

The HI-713 uses an adaptation of Standard Methods for the Examination of Water and Wastewater. 20th Edition, Ascorbic Acid Method. In this method, the compatible reagents that come with this Checker react with the water sample. The reaction between phosphate and the reagent causes a blue tint in the sample. This colour is then read by the Checker to provide an on-screen digital readout of phosphate levels in parts per million.

The HI-715 includes a reagents starter kit for 6 tests, so you can start testing the phosphate levels in your aquarium immediately out of the box.

Four steps to test

 

  1. ‘Zero’ the Checker with your vial & 10 ml water sample inside

  2. Take your vial out and add your reagent

  3. Place your vial into your Checker

  4. Press the button and read the results

Checkers vs test strips

Test strips are a popular choice for measuring phosphate within aquarium water. However, the accuracy of these tests rely on personal perception of the results, comparing the colour of the strip to determine how much phosphate is present. Hanna Checkers remove the guesswork in testing, providing a clear and accurate digital ppm result from testing, allowing you to swiftly make water condition changes to prevent algae bloom before it occurs.

HI713-11 Details:

The Phosphate Low Range Checker® HC Calibration Check Set – HI-713-11 provides a simple solution to validating the Phosphate Low Range Checker® HC – HI-713 in the range of 0.00 to 2.50 ppm (mg/L).

The HI-713-11 is a calibration checking set for the HI-713 phosphate Checker. This set is a single use calibration only.

Hanna optional Checker HC Calibration Sets provide a simple solution to validating your Checker HC. Each high quality set of standards is manufactured in our state-of-the-art facility and comes supplied with a Certificate of Analysis.

HI-713-11 is a high-quality set of calibration standards that allows users to validate the Phosphate Low Range Checker® HC – HI-713. The HI-713-11 includes one sealed cuvette for zero ppm phosphate and one single-use standard cuvette that becomes tinted to an equivalent 1.00 +/- 0.08 ppm phosphate sample @ 25°C when the supplied reagent is added. The calibration check set is produced using reagent grade chemicals in a temperature controlled environment.

Tip 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 or 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 such bubbles by swirling or by gently tapping the cuvette.

Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.

After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.

The Ascorbic Acid Method

These reagents follow the Ascorbic Acid Method in which the reaction between phosphate and reagent causes a blue tint in the sample. By simply adding the packet of HI-713-25 reagent to the sample, the reaction will take place and the HI-713 will determine the concentration from the colour that is produced.

The results will be displayed in ppm (mg/L) of phosphate. These reagents are designed to be used with samples that have an expected range of 0.00 to 2.50 ppm phosphate.
