Backpack Lab Soil Quality Educational Test Kit - HI3896BP

The HI3896BP is a Backpack Lab designed for educators and environmental science students, containing lessons, activities, and test kits that relate to important parameters evaluated in soil quality. Backpack Lab is designed with all the necessary components in one place, reducing the chance of misplacing an item. Ideal for transporting, it’s easy to take this durable backpack to the fišeld for on-site measurements. This portable kit contains well-constructed lessons and activities, and will allow the teacher to get the most out of their classroom time.

The HI3896BP contains test kits for the determination of common parameters in soil quality testing: nitrogen, phosphorus, potassium and pH. The HI98129 Combo Tester is also included for measurement of pH, conductivity (EC), and total dissolved solids (TDS), as well as the HI145-00 T-Shaped Thermometer for accurate temperature measurements.

Features at-a-glance

• Tests for seven important soil quality parameters

  • Classrooms can gain an extensive understanding of soil quality through measurement of these seven parameters:
    Nitrogen, phosphorus, potassium, pH, EC, TDS, and temperature.

• Complete testing setup

  • All required materials are included with the test kit, such as the pH tester, test tubes, indicator and reagent bottles and packets, and thermometer.

• Replacement reagents available

  • There is no need to buy a new kit when reagents are exhausted. The reagents and buffers for each parameter can be ordered individually.

• Comprehensive educational material

  • The lesson plan and components are tied together by a comprehensive teacher’s manual that includes information about each parameter, classroom activities designed to introduce students to each parameter, and detailed šfield-testing procedures.
