1、 Overview of TW-5328JS Immersion Acid Concentration Meter:

The new TW-5328JS immersion acid concentration meter is an online industrial analytical instrument suitable for installation in regeneration liquid pipelines or immersion in acid-base dilution tanks. Mainly used for monitoring the concentration of the regeneration solution of ion exchangers in the process of producing high-purity water by ion exchange method. This instrument can be applied to high-precision and continuous monitoring of the concentration of various strong electrolytes such as HCl, H2SO4, NaCl, Na2CO3 in industries such as power, chemical, metallurgical, food, and pharmaceutical.

IIMain features:
The new application of electromagnetic induction principle avoids the corrosion, pollution, and polarization effects of strong corrosive solutions such as acid and alkali on the electrode. It can read concentration values on-site and remotely monitor them, and work with computers or regulating devices to achieve regeneration program control and concentration adjustment. This can greatly improve the regeneration efficiency of the ion exchanger and avoid accidents such as calcium deposition in the cation bed and silica gel deposition in the anion bed, ensuring the safe and economical operation of the ion exchanger. There is no zero drift. High sensitivity, good stability, waterproof and anti-corrosion, easy installation and use, no need to extract water samples, no discharge of acid and alkali, *.
Adopting a fully plastic sealed shell imported from Finland, it can be used for a long time in extremely harsh humid, dusty, and corrosive environments. For the convenience of user selection, three types of sensors can be chosen, as shown in Figure 2.

4Ordering Notice:
When placing an order, the user must specify in detail the type of medium being tested, range, sensor model, including the installation method of the sensor (threaded or flange installation), and the cable length of the sensor. Our company produces and recommends the TW-5328J panel mounted display instrument specifically designed for concentration meters. It has a DC24V/0.4A DC power output, upper and lower limit alarm relay output function, and is equipped with a 0.8-inch LED display. The installation type is a panel mounted plug-in type, with a panel size of 160 × 80mm and a standard opening of 152 × 76mm. It is powered by AC220V and can also be matched with a wall mounted AC220V/DC24V power converter.
Sensor installation requirements: T-1 type sensors are of threaded installation type, with standard form G50 thread. The minimum installation thread is 1 "G thread or American standard 1" NPT thread. It can be screwed onto the matching circulation pool or installed on the flange. The minimum installation flange size for T-2 type sensors is DN65, and it is usually DN80~DN100 when paired with the main pipeline. The minimum installation flange size for the T-3 sensor is DN50, with recommended sizes ranging from DN50 to DN80. When placing an order, please provide detailed dimensional drawings of the installation site's tees. Our company can provide corresponding hard UPVC tees for easy on-site installation. Special size materials (such as epoxy fiberglass) can be discussed for processing.
