The HAMT-4000 water quality meter monitors tap water quality in real time. It analyzes five parameters simultaneously, including water temperature, electrical conductivity, residual chlorine, pH, and turbidity, to check the water quality status of tap water. The HAMT-4000’s specialized technology includes a bubble removal chamber to minimize the influence of bubbles in tap water when measuring turbidity, and an automatic cleaning device to minimize the influence of contamination on the sensor. Furthermore, it utilizes a non-powdered, rotary residual chlorine measurement system with an automatic cleaning function using ceramic beads to minimize the influence of sample flow rate, and automatic compensation for water temperature and pH improves the accuracy of measured values.
