Abstract

The invention discloses a pH meter for water quality detection, which comprises a main machine, a metering electrode, a temperature probe, an electric wire, and a calibration potentiometer. The metering electrode and the temperature probe are electrically connected to the main machine through the electric wire; the calibration potentiometer is installed in the main machine; a groove is formed in the metering electrode; a rubber sheath is installed on the upper end of the metering electrode; a plastic shell is arranged on the lower end of the metering electrode; a liquid crystal display screen is installed on the main machine; a transversal rod is installed on one side of the main machine, where two vertical rods are fixed to the middle of the transversal rod; a sleeve ring is arranged on the end of the transversal rod, wherein the diameter of the sleeve ring is larger than the diameter of the metering electrode and is smaller than the diameter of the plastic shell. The pH meter is convenient to use, has compact structure and is high in measurement precision.

Description

technical field [0001] The invention relates to a pH meter for water quality detection. 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, and scientific research. , pharmaceutical, fermentation, chemical industry, aquaculture, tap water and other fields. [0003] The level of the acidity meter and the accuracy of the instrument are two different concepts, and the level of the instrument is not completely consistent with its accuracy. The level of the acidity meter is expressed according to the graduation value (resolution or minimum display value) of its indicator (referred to as the electric meter), for example: an instrument with a graduation of 0.1pH is called a 0.1-level instrument;...
