WT-2000 Two Wire System Online PH
Product Introduction: All instruments are made of imported chips and components, using the latest surface mount production technology to ensure stable
Product details
Two wire industrial online waterproofingPH meterIt is an acidity meter with a two-wire wiring method, which consists of a high impedance electronic conversion unit, a glass electrode sensor, and a temperature sensor to form a measurement system. It uses low-power microcontroller technology internally to process the collected signals and can automatically identify and calibrate the calibration solution; The pH transmission range can also be freely set. As an instrument for continuously measuring the pH or ORP value of aqueous solutions in industrial processes, it is widely used in fields such as chemical engineering, refining, metallurgy, pharmaceuticals, and environmental protection.
Functional features:
1. High intelligence: The two-wire pH meter adopts high-precision AD conversion and low-power microcontroller processing technology, which can complete various functions such as pH measurement, temperature measurement, and automatic temperature compensation.
2. High reliability: Without complex functional switches and adjustment knobs.
3. Two line system: The instrument is connected to the outside using a two line system, which is convenient and simple to connect, has a long transmission distance, and strong anti-interference ability.
4. 4-20mA: The instrument has a 4-20mA output (without isolated output). If the user needs to isolate the output, please select the isolation module (isolation module is an optional accessory).
5. Instrument display: LCD intelligent display.
6. Automatic conversion of pH value of standard solution: The temperature curve of the standard solution is pre stored, and the pH value of the standard solution at the set temperature is automatically converted during calibration.
7. Automatic identification of incorrect calibration: If the user uses standard buffer solution incorrectly during calibration, the instrument will automatically prompt.
