Hand-held water hardness measuring instrument

Abstract

The invention discloses a hand-held detector for measuring water hardness, which comprises an instrument main body, a casing and a data line. The lower end of the instrument main body is connected with a dustproof cover through a pin shaft, and an indicator light is arranged outside the middle part of the instrument main body. A display screen is installed above the indicator light, and the display screen is located outside the main body of the instrument, the housing is arranged above the main body of the instrument, and a main shaft runs through the housing, and both ends of the main shaft are connected to the housing through bearings, and Both ends of the outer side of the main shaft are provided with a return spring, and a side baffle is installed inside the back spring, and the inside of the side baffle runs through the main shaft, and a tension mechanism is installed on the inner side of the side baffle, and a pressure plate is connected to the outside of the tension mechanism , and the pressure plate is located inside the side fence. The hand-held detector for measuring water hardness is equipped with a winding mechanism, which can facilitate the orderly winding of the outer lines, avoiding the winding of the lines, thereby avoiding the problem of reduced sensitivity of the device caused by long-term winding.

Description

technical field [0001] The invention relates to the technical field of water quality detection equipment, in particular to a hand-held detector for measuring water hardness. Background technique [0002] Water quality testing equipment is a device for testing water quality. It can detect water quality in real time, so that people can understand the surrounding water environment and facilitate understanding of the environment. The hand-held detector for measuring water hardness is a portable detection device. , can be carried conveniently, is easy to use, along with the development of science and technology, the detector of hand-held measuring water hardness has developed to a great extent, and its type and quantity are also increasing day by day. Although there are many types and quantities of hand-held water hardness detectors currently on the market, most of the hand-held water hardness detectors cannot rewind the outer line, which is prone to entanglement, and it is easy ...
