Nowadays, many children do not show interest in STEM subjects. They find them difficult, incomprehensible and abstract. How to understand what is very often not visible to the eye? It is in solving these problems that their teachers play the greatest role. It is up to them to make their lectures interesting and understandable, to show children how fun STEM subjects are. One way you can bring STEM science closer to them is to move your classroom to the field.
We at Hanna care immensely about the coming generations and fully understand that STEM sciences are the future of our young generations. We believe in popularizing STEM science and we work diligently and constantly on how to popularize science and bring it closer to children and encourage them to study in that direction.
To help you teach Hanna has a very simple, fun and interesting solution!

If you would like to carry your classroom outside like a pro, there are suitcases you can take it with you!
Water Quality Test Kit – HI3817
The HI3817 is a chemical test kit that measures six parameters common in water quality testing: alkalinity, chloride, hardness, iron, pH, and sulfite. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter, with the exception of iron, which includes reagents for 50 tests. pH is obtained with Hanna‘s pHep®, pH electronic tester, which guarantees greater accuracy and a longer life than traditional litmus paper.

Environmental Monitoring Chemical Test Kit – HI3814
The HI3814 is a chemical test kit for the determination of six parameters commonly monitored for environmental testing: acidity, alkalinity, carbon dioxide, hardness, dissolved oxygen, and pH. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna‘s pHep®, pH electronic tester, which guarantees greater accuracy and a longer life than traditional litmus paper.

NPK Soil Chemical Test Kit (25 tests each) – HI3896
The HI3896 is a chemical test kit for the determination of commonly monitored parameters in soil testing. By using Hanna’s Soil Test Kit, it is possible to measure pH and the most important elements for plant growth: nitrogen (N), phosphorus (P), and potassium (K).This kit is equipped with all the necessary reagents and equipment to perform over 25 tests for each parameter.

Many schools struggle with tight budgets and therefore cannot afford large laboratory instruments. But not every purchase has to be expensive to achieve the desired effect.
Our devices work quickly and reliably. They are easy to handle and show the students that we have long arrived in the technical future and that litmus paper is not the only way to measure pH!
We offer a wide range of measurement devices to cover different budgets and different parameters such as temperature, pH and EC: HI98501, HI981030, HI98129, HI98304, HI991301




To color your classroom and show children how to measure some of the most important parameters in our enviornment, use Checkers. Simply measure chlorine, iron, freshwater alkalinity, phosphate.




To guide your students into the future introduce them to HALO electrode. HALO is the world’s first professional pH probe with Bluetooth Smart technology (Bluetooth 4.0). This technology is energy efficient, allowing for low power consumption to maximize the life of the replaceable battery used in the pH electrode. HALO pH probes can be used virtually anywhere: in the field, laboratory, or classroom. Their versatility and ease of use revolutionizes the way pH is measured.

o quote Martin O’Malley:
“The most valuable investment we can make is in our children’s education. When we make education a priority, we give our children opportunity. Opportunity to learn at higher levels than their parents were able to learn; to earn at higher levels than we were able to earn.”
