Use the Water Depth Sampler to collect water samples from any desired lake depth.
Use this device to collect water samples from any desired lake depth. You can raise samples to the surface, and make on-site measurements of dissolved oxygen, pH, temperature, or conductivity using Vernier sensors (sold separately)) and a Vernier interface (sold separately) take some samples back to the school for testing. The Water Depth Sampler has a unique trigger mechanism that requires only one line to raise and lower the chamber and also to seal the 1.5-liter chamber. A 50-foot nylon drop cord is included.
