Product details
Typical applications:
The full name of dissolved oxygen meter is computer dissolved oxygen controller, which is 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:
DO4100 is our company's new highly intelligent all Chinese microcomputer controller
★ LCD large screen display, full Chinese menu operation, human-machine dialogue, microcomputer operation.
Display DO value, input mV (or output current), temperature, time, and status on the same screen.
★ Equipped with components, the dual high impedance input impedance can reach up to 10P12P Ω, and it has strong resistance to Gan interference.
★ The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and can be transmitted remotely.
The communication interface can be easily connected to the computer for monitoring and communication.
★ Automatically achieve wide range measurement from ppb level to ppm level.
