From Hanna , HI 83215 is a practical instrument made for the hydroponics and greenhouse industries to measure nutrients commonly present in fertilizer enriched solutions.
This photometer measures ammonia, phosphorus, nitrate and potassium in three distinct ranges of low, medium and high concentrations. This way accuracy is maximized for each nutrient and for every concentration. Thanks to the simplicity of the operations, you no longer need to send off your samples and then wait for the results to come back. Armed with HI 83215, you can test the presence and strength of nutrients right on the spot. This can translate itself into a substantial savings and improved yield over a period of time. The internal microprocessor provides high accuracy and simplifies operations to the degree that even non-technical operators can use the meter. In fact, the meter is supplied complete with all the necessary accessories. Just source the reagents needed from the table below and commence measurements. HI 83215 runs on batteries as well as the mains and comes complete with 9 volt batteries and a 12 Vdc adapter. Add to this the units light weight and you have a bench meter that is just at home in the field as in the horticulturists lab.
HI 83215 is supplied complete with 4 measuring cuvets, batteries, 12 Vdc adapter and instructions.
