Designed as a more accurate alternative to chemical test kits, the HI700, HI715, and the HI733* provides quick, accurate results. Step One - Add a sample to the included cuvette(s). Step Two - Insert sample into the Checker HC and press the button to zero. Step Three - Remove sample and add reagents as the manual states. Step Four – Reinsert sample, press and hold the button for 3 seconds to start reaction timer. reading will be taken automatically and the results displayed. * HI733 uses a different procedure All three models use 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 sample. See page10.166 for Checker HC accessories www.hannainst.com | 10 10.139 Photometers Checker®HC
