HANNA HI 83225 Multiparameter Photometer, Hydroponics and Greenhouse

HANNA HI 83225 Multiparameter Photometer, Hydroponics and Greenhouse

HI 83225 is designed for the hydroponics and greenhouse industries to measure nutrients commonly present in fertilizer enriched solutions. This photometer measures ammonia, phosphorus, nitrate, potassium, calcium, magnesium and sulfate. Ammonia, phosphorus, nitrate and potassium can be measured in three distinct ranges of low, medium and high concentrations. This way accuracy is maximized for each nutrient and for every concentration.

Due to simplicity of operation, you no longer need to send off your samples and then wait for the results to come back. With the HI 83225, you can test the presence and strength of nutrients right on the spot. This can translate itself into a substantial saving 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 this meter.

This meter is supplied most accessories. Reagents are necessary and sold separately. All numbers listed are for 100 tests unless otherwise noted. HI 83225 runs on batteries as well as a 12 Vdc adapter and is supplied with both. An exclusive positive-locking system ensures that the cuvet is in the same position every time it is placed into the measurement cell. Display codes aid the user in routine operations. The meter has an auto-shut off feature, turning the unit off after 10 minutes of non-use.

Reagents are in liquid or powder form and are supplied in bottles or in packets. The amount of reagent is precisely dosed to ensure the maximum repeatability.

The HI 83225 can be connected to a personal computer via the HI 920010 RS 232 cable. The HI 92000 HANNA Windows® Compatible Software aids the user to manage all test data. Plant Nutrition

The three elements that are most needed by plants are nitrogen (N), phosphorous (P) and potassium (K).

Nitrogen is indispensable for the plant’s life and is a key factor in fertilization. Nitrogen allows the development of the vegetative activity of the plant, in particular, causes lengthening of trunks and sprouts and increases the production of foliage and fruits. An excess of nitrogen weakens the plants structure creating an unbalanced relationship between the leaves and the stalks. In addition, the plant becomes less resistant to diseases.

Phosphorous is an important element in the composition of DNA and RNA, the regulators of the energetic exchange (ATP & ADP), as well as the reserve substances in seeds and bulbs. It contributes to the formation of buds, roots, blooming, and lignification. A lack of phosphorous results in: stifling of plant, slow growth, a reduction of production, smaller fruits and a lower expansion of the roots.

Even if Potassium is not a constituent of important compounds, it plays a remarkable role in many physiological activities like the control of cellular turgor and the accumulation of carbohydrates. It increases the size of fruits, their flavor, as well as yielding a positive effect on the color and fragrance of flowers. Potassium also makes plants more resistant to disease.
