EN-701 Acid concentration analyzerDetailed product description：

The EN-701 acid concentration analyzer is a new generation product developed based on electromagnetic sulfuric acid concentration measurement instruments and field applications. A sensor made of a ring-shaped iron core is placed in a sulfuric acid solution. The solution surrounding the sensor forms a dielectric solution circuit through a central hole. The equivalent resistance of the solution circuit is Re=K/Xe (K is the magnetic head constant). The magnitude of the induced current Ie in the solution circuit is determined by the equivalent resistance Re of the solution, which is the conductivity Xe of the solution.

The main features of EN-701 acid concentration analyzer are:
The instrument sensor is formed by PTFE sealing and welding, with a simple structure and reliable performance. For the acid concentration measurement part, due to the sensor being encapsulated in a PTFE material cover that is not corroded by the measuring medium, it has a long lifespan and minimal maintenance.
The detector components installed on site are compact in structure, small in size, and easy to install.
The instrument has a wide temperature compensation range, strong interchangeability, and is easy to maintain and replace components.
Adopting current signal transmission and optoelectronic isolation technology, the instrument has strong anti-interference ability.
