Thermometer

Found in all testkits

This is a basic waterproof thermometer to test air temperature or water temperature. For air temperature, hang in the shade away from anything that radiates heat (buildings, on your body).

Secchi disc

Found in Freshwater Explorer, Freshwater Explorer +, Ocean Explorer and Junior Freshwater Explorer (go to the store)

A secchi disc is the industry standard for lake clarity levels. Lower the disc down until you can’t see it anymore. Unfortunately won’t help you with stream clarity, but you can use it to measure water depth when you can see the bottom!

Test strips

Found in all testkits

We use test strips to easily determine pH, alkalinity, hardness. We have tested many different types of test strips, and have found these HTH strips to be the best. Check out the comparison here.

pH

Alkalinity

Hardness.

Conductivity meter

Found in Mr. Mini Freshwater, Freshwater Explorer, Freshwater Explorer +, and Junior Freshwater Explorer (go to the store)

We have tried out many inexpensive conductivity meters, and we’re pretty happy with this one: it’s accurate within 5% of the expensive YSI we’ve compared it to, and it’s pretty water resistant. At this price, it’s the best value we could find! It also has Automatic Temperature Compensation (ATC), and you can use it for your water temperature reading too. It holds its calibration well, but will have to be tested each testing season.

Sample containers

Found in Freshwater Explorer, Freshwater Explorer +, Ocean Explorer and Junior Freshwater Explorer (go to the store)

We provide you with a sample cup. Nothing special, but when you can’t test directly in the water, it’s a great way to collect some to test later. Be sure to thoroughly rinse the cup before and after each use!

Refractometer

Found in Ocean Explorer (go to the store)

The refractometer is a great way to find out what salinity is. It is easy to calibrate too, with some distilled water and a screw driver (provided). It comes with a water dropper to put a small water sample on the screen, and a cloth to clean the surface after you’ve used it.

CHEMets Dissolved Oxygen Kit

Found in Freshwater Explorer +, and Junior Freshwater Explorer (go to the store)

This kit is so fun, and feels so amazingly scientific, without the usual possibilities of getting chemicals on yourself or error caused by titration. Push the ampule into the bottom of the sample, let the water fill the ampule, invert, and then let it develop for two minutes. We tested this against a few YSI devices, and it was generally correct! Because it’s a colour metric test, you won’t get the precision of a device. It is a great test to get a general idea of oxygen in the water, where low levels could mean problems, and a great indicator if extra testing is necessary.
