Hanna Hi 98129 - Maintenance Aspects Of This Combo Reader

There are several situations when it is necessary to measure the pH of fluids and semi-solids. If you are a gardener, you need to know the pH of the soil (in your garden). In chemical labs, you sometimes need to know the pH of liquids before mixing or heating them. If you work in food processing, knowing the pH of substances is also essential. It's also important to be able to measure the conductivity and temperature of other liquids in fields like industrial engineering and environmental applications. In some cases one needs to be able to measure these three variables (pH, conductivity and temperature) at the same time. Although separate pieces of equipment can be used to measure each of them, there are special tools that allow you to measure these three variables and more, using only one device. One model is the Hanna HI 98129.

The Hanna Instruments HI 98129 is a pen-like tester that you can use to measure the pH, conductivity, temperature and even TDS (Total Dissolved Solids) of several different substances. It works via an electrode that can be removed and easily cleaned after testing by using a special tool that comes with the tester as well as a small cloth. Using the HI 98129 to take measurements is very easy: you simply remove the cap, select the variable you wish to measure, place the electrode in the fluid to be analyzed, and wait a few seconds until the tester produces the desired reading. Just because it is easy to use, however, doesn't mean its maintenance is equally as simple!

In order to properly maintain the HI 98129 it is necessary to buy specific solutions. These come in 8 ounce bottles and each one has a separate function. The 7.01 pH solution and the 4.01 pH solution are required to calibrate the pH readings of the tester. The 1413 mS/cm solution is needed to calibrate its conductivity readings. It is also necessary to purchase a cleaning solution to clean up the electrode. It is recommended that to use this solution at least once a day in order to prevent clogging in the electrode and to maintain accuracy in the readings. Finally, there is the storage solution, of which a small amount is placed in the cap of the HI 98129 combo tester while it is not in use. It keeps the electrode moist, which helps maintain accuracy, fast response times and overall functioning.

The Hanna HI 98129 definitely needs a great deal of maintenance! Having to buy four bottles of solutions along with the product may cause customers to feel financially squeezed, and having to calibrate it and clean the electrode so often may seem frustrating. That is the maintenance that the device needs, though; there's no getting around it. However, if you purchase these solutions, use them properly and follow the maintenance procedures correctly, the tester will always work properly and will provide fast and accurate readings for all of the measurements that you need to perform.
