摘要: A miniature water quality sensor, comprising a casing (1), circuit board (2) provided with sensor head (21) for immersion in water, and battery (3). Control switches display screen (22) used displaying measured values (24) are arranged on the (2). first through-hole (11) accommodating is (1). The immersed to be tested, provides power, of displays measurement value, thereby measuring water. present small size, can carried bag, pocket or other place, being thus easily portable.
