PWS Cl Tester, drop tester

Drop tester for determining the chlorine or bromine content of pool water. The tester works by using reagents to colour the water a certain shade and comparing it to a colour scale to determine the measured value. The contents of each container should be sufficient for approximately 120 measurements. So 120 chlorine or bromine measurements. Also included is a calibration chart for chlorine and bromine, one sample container and instructions.
