The HI-700 Ammonia Low Range Checker is a simple, accurate and cost effective way to measure low ranges of ammonia in fresh water. Designed as a more accurate alternative to chemical test kits, the HI-700 provides quick, accurate results in four easy steps.
Test Results in 4 Easy Steps
Quick results from a single button in 4 easy steps. First zero the Checker with an empty vial inside. Next place a 10ml water sample inside the vial and add the included reagent. Return the now full vial to the checker. Press the button and read the result.
More Accurate than Chemical Test Kits
The checker uses an adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler method. The reaction between ammonia and reagents causes a yellow tint in the samplewhich is then read by a colorimeter. The result given is accurate to ±0.05 ppm between 0.00 to 3.00 ppm. Most chemical test kits on the market are only accurate to ±0.2ppm.
Hand-held Portable Design
Small compact size with a single button and powered by only one AAA battery (included) makes these Checkers from Hanna Instruments incredibly versatile and portable. Perfect for aquarists, aquaculturists, fish keepers, and even scientists in the field.
