1、 Measurement principle
TriOxmaticThe polarographic thin film electrode adopts a constant potential three pole testing system. Working electrode made of gold(A)Silver reference electrode(R)With auxiliary electrodes(G)Compared to traditional two electrode sensors, the three electrode system adds an auxiliary electrode and a working electrode to form a current loop, and uses a reference electrode to control the potential, effectively avoiding polarization of the reference electrode and greatly enhancing the stability of the entire system.
2、 Typical applications
1、 TriOxmatic®700/1 IQControl and monitor the inflow process of the biochemical pool
2、 TriOxmatic®702 IQLow concentration dissolved oxygen water quality, such as monitoring boiler feedwater or purified water
3、 Advantages and Characteristics
(1) Work safety and reliability
The built-in high-performance preamplifier adoptsSMDSurface packaging technology ensures that long-distance transmission is not interfered with, at least up to100Rice.
(2) Long service life
Due to the low consumption of electrolyte and large storage capacity, it has a long service life and is theoretically at least usable5Year.
(3) Maintenance Province
The replacement of the encapsulation cover film and electrolyte is simple and convenient. in additionWTWusedTeflonThe film is very resistant to pollution, and pollutants are not easily attached, ensuring normal and reliable testing without the need for cleaning.
(4) High testing accuracy
WTWThe dissolved oxygen electrode test is accurate, with an accuracy of up to within the entire testing range1%Test value.
(5) The reading remains stable from start to finish
allWTWThe dissolved oxygen electrode can provide stable and reliable readings from the beginning:
1The failure rate is very low
2Long term drift with small zero drift
