Chinese online pH meter

5201P typeChinese online pH meter

5201P typeChinese online pH meterIt is our company's new generation all Chinese microcomputer high-end instrument, which has the characteristics of full Chinese display, Chinese menu operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptabilityindeedMeasure the pH value and temperature of the solution. It can be widely used for continuous monitoring of ORP values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

Main Features:

◇Chinese LCD display, Chinese menu style operation, Chinese note taking

◇Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, and instrument self-test with high accuracy and good repeatability.

◇High reliability: Single board structure, touch sensitive buttons, no switch knob or potentiometer.

◇Waterproof and dustproof design: protection level IP65, suitable for outdoor use.

◇Electromagnetic compatibility (EMC/RFI) design: Designed and manufactured according to European standard EN50081/50082.

◇Realize 25 ℃ conversion: Nernst electrode slope temperature compensation, pure water and ammonia added ultrapure water conversion at 25 ℃

◇Dual high resistance input circuit: low internal resistance PH electrode, good instrument stability, fast response, strong anti-interference.

◇Solution ground connection: eliminate ground circuit interference.

◇Electrode diagnosis: Multiple calibration methods, E0 and S queries, monitoring electrode performance.

◇Automatic alarm function: Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm lag cancellation

◇Network function: isolated current output and RS485 communication interface; The output upper and lower limits of the ORP value corresponding to the current can be set arbitrarily.

◇Industrial control watchdog: ensures that the instrument does not crash.

◇Historical curve: Continuously record data for one month, with one point every five minutes.

◇Notepad function: Record 200 pieces of information.

◇Manual current source: convenient for recording and testing devices.

◇Built in real-time clock: provides time benchmarks for various functions, etc.

◇Password management: Calibration, parameter setting, and maintenance all have password protection.
