The Handheld Colorimeter is a valuable accessory for your Water Test Kits, as it allows you to measure the true color of water more effectively.

The true color is the color of water free of suspended solids, and it can indicate the presence of dissolved compounds that can be natural, artificial, or both.

The color of water containing both dissolved and suspended solids is called apparent color, measured in Platinum-Cobalt units (PCU).

According to the AWWA (American Water Works Association), the recommended limit for apparent color is less than 15 PCU. The CMT Colorimeter is a small and easy-to-use device that can measure the true color of water with more accuracy than chemicals.

It is also more convenient and portable than chemicals, as you only need one device to perform the test.
