The GM20 low-speed well washing multi parameter system is a portable and intelligent water quality data acquisition device, specifically designed for underground water sampling and well washing work. The samples are collected through a closed circulation pool to obtain on-site data, which can be used to measure turbidity, temperature pH、ORP、 The measurement of six parameter data, including conductivity and RDO optical dissolved oxygen, provides more authentic and representative data, which can be printed on site as a result report.

The instrument is operated and controlled through a handheld data terminal connected via wireless Bluetooth. The self-developed low-speed well cleaning software can clearly display the overall status, data recording, sensor status, and connection of the device, making on-site operation convenient.
