Product Description:

Monitor multiple water parameters with the C-600 7-in-1 Digital Water Quality Tester Pen.

This compact handheld tester combines pH, TDS, EC, ORP, salinity, specific gravity and temperature measurement functions in one portable device. The green backlit LCD screen displays readings clearly, while the simple front-button layout allows users to switch between measurement modes, hold a displayed result and access calibration functions.

The tester can be used to check water samples from aquariums, hydroponic systems, swimming pools, fish ponds, saltwater tanks and household water systems. Its slim pen-shaped body is easy to carry, while the removable protective cap helps protect the electrode when the tester is not in use.

For best results, rinse the probe with distilled or clean water before and after testing, follow the supplied calibration instructions and allow the displayed value to stabilise before recording the reading.
