Despite what it looks like, she is quite flexible

5/5

It is common for manufacturers to limit the number of instruments available for sale to encourage additional sales. The instrument you are holding is part of that group.

According to my research, the wavelengths are determined by the LED color, while the countdown time is determined by a resistor in the base of the unit. In summary, a single device can be used to measure several parameters providing that the reagents and reaction times are correct. The following are the results of my testing.

It didn't work out the way I expected it to

3/5

Based on the information I had regarding our water supply, the results I got when I used this test kit did not make sense. In the following weeks, I acquired my Test kit 70 of the Chlorine book that I purchased gave me reliable results. My tests were run twice and I followed the directions. Maybe I did something wrong, but I am not sure what I did wrong. Simple instructions make using the test kit easy.
