A ph meter online automatic purging device

Abstract

The invention relates to an online automatic purging device for a pH meter, comprising a rainproof cover, a connecting cylinder, a mounting base and an air source pipe, the connecting cylinder is arranged vertically, the rainproof cover is connected to the upper end of the connecting cylinder, The installation base is connected to the lower end of the connecting cylinder, a sealed chamber is arranged in the installation base, a pH meter is fixed in the sealed chamber, the air inlet end of the air source pipe is connected with compressed air, and the air The gas outlet end of the source pipe passes through the rainproof cover and the connecting cylinder in turn, and protrudes into the sealed chamber in the installation base, facing the pH meter. The invention uses compressed air to clean the pH meter for detecting sewage or other crystallization-prone solutions without adding other media and does not affect the pH value of the measured solution, and has simple structure, easy operation and high work efficiency.

Description

technical field [0001] The invention relates to an online automatic flushing device for a pH meter, and relates to an online automatic flushing device for a pH meter by using compressed air in an environment where the measurement medium is turbid and easy to scale. Background technique [0002] The pH meter is a commonly used instrument and equipment, mainly used to precisely measure the pH value of the liquid medium. It can also measure the MV value of the ion electrode potential with the corresponding ion selective electrode. The pH meter is widely used in environmental protection, sewage treatment, scientific research, Pharmaceutical, fermentation, chemical industry, aquaculture, tap water and other fields. The instrument is also an essential inspection equipment for QS and HACCP certification in food factories and drinking water factories. [0003] However, when the pH meter is used in an environment where the medium is prone to crystallization, the pH meter is prone to...
