Product Details
Product introduction
The Galvanic Cell method dissolved oxygen digital sensor is a new
generation of intelligent water quality detection digital sensor
independently developed by our company. It can check, calibrate,
maintain through mobile phone or computer. It’s easy to
maintenance, with high stability and good repeatability. Its’
function it to test the DO value and temperature of liquid. It is
widely used in waste water treatment, purified water, circulating
water, boiler water and other systems as well as continuous
monitoring of dissolved oxygen values in solutions such as
electronics, aquaculture, food, printing and dyeing,
electroplating, pharmaceutical, fermentation, chemical and other
farming and tap water.
Main features
- This product is a DO digital sensor, which can directly output
RS485 signal and 4~20mA signal.
- The product has high precision, high stability and strong
anti-interference ability.
- Automatic temperature compensation.
- No need for instrumentation, can directly connect to computers, PLC
and other devices with RS485/4-20mA signal interface for data
acquisition and maintenance; it is convenient for users to
integrate sensors into the industrial computer system such as PC
system and IOT.
- The sensor can be set by RS485 communication, slave address and
baud rate, online calibration, factory reset, 4-20mA output
corresponding range , proportional coefficient and incremental
compensation.
- Two-point calibration method is used.
- Power off protection > 10 years.
