DO200 dissolved oxygen sensor /industrial online dissolved oxygen analyzer
Product introduction of dissolved oxygen sensor
DO - 200 dissolved oxygen meter is an online intelligent testing instrument for dissolved oxygen ,adopt imported components and dissolved oxygen membrane combined with advanced production technology , insure the meter work stable and reliable for long time.
1.Electrode zero, automatic judgment for slope overrun.
2.Photoelectric coupler isolation protection 4 ~ 20 ma output signal, the input signal and output signal without interference
3. EEPROM memory, not need backup battery, data do not lost when the electricity is cut off; Temperature excursion small, stable, accurate
4. Operation menu design is unique, avoided the tedious operation , use convenient beyond imagination
5.Big screen multiple parameters (value of dissolved oxygen, temperature, output current can be display at same time) LCD backlit display, intuitive easy to read
6.without keystrokes backlight automatically shut down in three minutes, power saving and can prolong the service life
7The screen contrast level can be adjustable ;High and low alarm point can be set freely; can display the alarm status directly on the screen and be accompanied by switch ON/OFF signal output at the same time
8 retardation set arbitrary function freely, avoid relay frequent action
9RS485 communication optional;use the waterproof and air hermetic flame retardant shell, tection grade IP65, more can be used in harsh environmental conditions, can be widely used in chemical fertilizer, metallurgy, environmental protection water treatment engineering, pharmaceutical, biochemical, food, aquaculture and water such as continuous monitoring of dissolved oxygen in the solution.
