PH automatic control liquid addition system (high flow control)

Instrument Overview

SC-500A plustypepHThe automatic control liquid addition system ispHOnline display, measurement, and automatic addition of values(sour/alkali)A new type of automated control system that integrates liquid adjustment. Widely used for control and regulationpHPlaces of value include: laboratory researchers monitoring and controlling the acidity and alkalinity of solutions in various reaction vessels, reaction tanks, biochemical containers, catalytic fields, and bioreactors.

This system is the third generation high-precision developed by the companypHAutomatic control system for laboratories in higher education institutions and research institutes,Specially designed and manufactured by domestic and foreign R&D enterprises and R&D production departments, and possessing independent intellectual property rights. Obtained a national invention【ZL201410349779.8】And multiple utility models【ZL201721373766.X】; 【ZL 201420406067.0】; 【ZL201420406055.8】. The whole machine adoptsPLCControl and connect with a customized peristaltic pump to automatically adjust the solution in the container by adding acid or alkalipHThe preset value. It is ideal for laboratories such as catalysis, pharmaceuticals, chemical engineering, electroplating, biochemistry, biological fermentation, plant extract workshops, scientific institutes, or small production testing sitespHMonitor the automatic control system.

Performance characteristics

1ThepHIntegrated detection, display, and automatic liquid addition, capable of processing solutionspHStatic or online detection adjustment.

2, can be carried out topHThe test solution with value as the indicator can be controlled and added. The peristaltic pump can operate independently and can be used for other experiments.

3Integrated touch screen display, Chinese operation interface, displaying both control settings and measured values simultaneously.

4AdoptingPLCControl the precise control of the liquid addition pump speed and adjust the liquid addition speed in real-time.

5It has multiple control measurement modes: automatic, manual, stop and other liquid addition functions, which can be freely switched.

6Customized with low impedance and high precisionpHComposite electrode, fast response, suitable for various working conditionspHmonitor.

7The stepper motor controls the peristaltic pump to add liquid, with good controllability,The fluid only comes into contact with the pump tube, not the pump body, and has no pollution.

8Using acid and alkali resistant liquid addition pipes and imported pump pipes to form a sealed pipeline connection, with a long service life.

9ThepHHigh measurement and control accuracy, flow rate can be automatically adjusted, and users can set the appropriate flow rate according to the usage process

10It can avoid the physical harm caused by organic solvents to experimental personnel when adjusting the solution, and also improve work efficiency
