EarthEcho’s Water Challenge Test Kits are easy-to-use and enables anyone to sample local water bodies for basic water quality parameters: temperature, pH, turbidity, and dissolved oxygen. These kits are ideal for field use, supporting reliable environmental monitoring with a compact, lightweight design.

The Water Challenge Test Kits (1 box of 5 individual kits) include essential components for basic water quality testing:

  • 5 Instruction booklets (English/Spanish)
  • 5 Sample collection jars
  • 5 pH test tubes
  • 5 Dissolved oxygen vials
  • 5 Secchi disk decals
  • 10 Temperature strips (5 14-40°C and 5 0-12°C)
  • 50 pH reagent tablets (enough for 50 tests)
  • 100 Dissolved oxygen reagent tablets (enough for 50 tests)
  • 5 Color charts for determining DO, pH and turbidity test results
  • 5 Mini pencils
  • Kit specifications: 13 x 13 x 4 in; 2.1 lbs per box

*This product contains 5 total testing jars and enough reagents to conduct up to 50 individual water tests of pH and dissolved oxygen. For a class of 25 students, 1 classroom kit works perfectly. Students can work in groups of 5, with each group testing all included water quality parameters. This scenario will allow for 10 tests per sample jar, allowing you to run monthly water quality testing with your classroom.
