Inconvenience, can seriously cause the failure of controlled industrial equipment, and sewage discharge is unqualified, the problem of pollution environment.
It has been investigated that the appearance of above mentioned problem, electric potential signal, insulation mainly due to the glass sensitive membrane of pH electrodes
Caused by the parameter such as characteristic and the noise signal of electrode signal transmission cable.Electrode is easily by extraneous temperature, humidity, tested water
The influence of electromagnetism harmonic wave interference in sample conductivity value, dielectric insulation degree, signal-transmitting cable self-noise and air, and cause pH
The unordered fluctuation of electrode signal, so cause measured value change, it is inaccurate.
The content of the invention
To solve the above problems, the present invention provides a kind of measured value accurate, stable measurement water quality pH value device.
Scheme of the present invention is：Measuring instrumentss in device are connected by common cable and impedance transducer one end
Connect, the impedance transducer other end is directly connected with measuring electrode, shorten the transmission range of high resistant signal, it is ensured that signal is not damaged
Lose and improve interference free performance.Impedance transducer is externally provided with electrode cap, and electrode cap has the effect of protection impedance transducer.Electricity
Sealing is provided with polar cap, the sealing is high insulation and shielding material.The impedance transducer other end is also associated with reference electrode, glass
Glass ball bubble, temperature electrode.
Using the measurement apparatus of this structure, when measuring water quality pH value, signal antijamming capability is improved, is measured
Water quality PH numerical value it is accurate, and stably.The numerical value that this invention is measured not only is stablized, accurately, and the transmission of signal
Distance is still stablized after extending hundreds of meters, expands the use scope at scene.
