CHEMICAL MONITORING UNIT AND METHODS

Disclosed is a pool water monitoring system and monitoring techniques. A pool monitoring system may include a monitoring unit and a computer application. The monitoring unit includes a surface based unit, a submersible cable connection assembly, and a submerged sensing device. The submerged sensing device is configured to measure water parameters, a submersible cable connection assembly connects the surface based unit and the submerged sensing device together. The surface based unit is configured to receive the measured water parameters via the submersible cable connection. The surface base unit is operable to wirelessly communicate with the computer application of the client device. The computer application is operable to receive the measured water parameters transmitted by the surface base unit; evaluate the measured water parameters; and present indications, on a touchscreen of a client device, of the measured water parameters and evaluation results of the measured water parameters.
