• pH probe

• Conductivity & Temperature probe

• Nitrates/Ammonium probe

A student is using the YSI Handheld Multimeter to test a water sample. They want to check for the presence of ammonium. Which probe should they select?

• Nitrates/Ammonium probe

• pH probe

• Conductivity & Temperature probe

• Dissolved Oxygen probe

Which piece of equipment is specifically used to collect water samples from the middle of a waterway?

• Stage Tape

• Van Dorn

• Secchi Tube

• Phosphate Test Kit

How does the Secchi Tube contribute to water quality analysis?

• It measures the distance to the sampling point

• It collects water samples from the surface

• It measures the turbidity or water clarity of a sample

• It tests for chemical contaminants

What is the purpose of the Phosphate Test Kit in water analysis?

• To measure water temperature

• To measure the distance to the sampling point

• To separate and measure the phosphate present in water through a chemical reaction

• To measure water clarity
