HI 93732N Dissolved Oxygen Measurement Made Simple!
|
| *(Valid only in USA) |
|
In order to measure DO, operators are normally presented with a limited choice between chemical test kits and DO Meters using a probe. The test kits are somewhat cumbersome and inaccurate. They often provide only an approximation of the true value of dissolved oxygen in a sample. On the other hand, DO meters with probe and cable provide a more accurate result. However, the measurements can be susceptible to temperature, altitude and salinity variations. The membranes utilized on the probes also require frequent replacement. The test kits cost a fraction of the DO meter but with scarce accuracy. In fact, many operators in fish farms, forgo the measurement of DO as often as needed, or refrain from delegating to non-technical users due to the prohibitive cost or complexity of these instruments.
We are happy to inform you that there is now a third and more effective choice: HI 93732N. The Hanna HI 93732N utilizes a sophisticated custom microprocessor and a modified Winkler method to measure Dissolved Oxygen accurately and quickly. Measurements are made in a few short steps that can be performed by technical and non-technical operators alike. In fact, all you need to do is insert a cuvet containing your sample into the meter and press ZERO. This will calibrate the meter to your sample in seconds. Then add a few drops of the reagents to the sample to generate a color whose intensity depends on the DO content. Place the reacted sample back in the meter and the instrument will do the rest of the work for you!
HI 93732N will display the DO concentration in tenths of ppm in clear digits and on a large LCD. No need to worry about temperature changes, membrane status or salinity variations. Ease of use and accuracy are not the only qualities of the Hanna HI 93732N.

HI 93741 Total Hardness & Iron Meter
|
| * (Valid only in USA) |
|
HI 93741 can provide critical measurements of Low Range Iron and Total hardness (Magnesium & Calcium). The iron concentration in water needs to be monitored since it can become harmful above certain levels. In domestic water, for instance, iron can alter the taste and make it unpleasant, stain laundry, damage kitchenware and favor the growth of certain bacteria. Low levels of iron are also critical in beverage production.
Hardness, on the other hand, is indicative of presence of calcium and magnesium in water. By passing through various layers of soil & rocks, rainwater dissolves some of the mineral substances. Hardness is a consequence of the type of rock layers which the water passes through and of its permanence in the water bearing stratum. Hardness can cause pipe rusting in water heating and cooling systems, reverse osmosis and demineralization plants. It can also increase the consumption of soaps and detergents in industrial washing machines or laundries. With the portable HI 93741 you can keep a watchful eye over both Iron and Hardness levels.
