Portable DO Meter
Description of DO Meter:
XY - 4000 DO Meter with microprocessor monitoring instrument online of water quality. The instrument configuration of the different types of dissolved oxygen electrode is widely used in power plants, petrochemical industry, metallurgy, electronics, mining, paper, fermentation, pharmaceutical, food and beverage, environmental protection water treatment, aquaculture, and other industry. For continuous monitoring of dissolved oxygen (do) value of the aqueous solution and temperature and control.
Features of DO Meter:
1. LCD liquid crystal display screen
2. Manual/automatic temperature compensation
3. A variety of automatic calibration function
4. Two sets of relay control switch
5. High limit / / low limit / / hysteresis control
6. RS232 / RS485 communication connection
7. Double optional signal output current/voltage output
8. The same interface display value of dissolved oxygen and temperature
9. Set password to prevent non-work personnel wrong operation
