Typical Applications
Widely used for online monitoring of dissolved oxygen in thermal power, chemical industry, metallurgy, water treatment, pharmaceuticals, biochemistry, electronics, electroplating, printing and dyeing, chemistry, food, and tap water.
Instrument Features
● Multiple configurations. The ordinary configuration uses an 8-bit microcontroller and the configuration uses products such as a 32-bit machine, ARM system, and CAN bus replacement technology, which belong to highly intelligent and reliable instruments. Chinese character menu style operation
The oxygen electrode has high sensitivity, short response time, high temperature resistance, collision resistance, corrosion resistance, and no deformation. It is easy to maintain and replace molds
LED dot matrix LCD display, displaying data, status, and operation prompts in Chinese, with adjustable background light
● Automatic temperature compensation
● Store over 500 sets of data
Automatically record historical events such as instrument status, faults, and occurrence time, commonly known as notepad function
● Using USB 2.0 communication port for data transmission
● Built in high-energy lithium battery, charged through computer USB port or charger, automatically protected against overcharging
