This meter is a perfect combination with the most advanced electronic, sensor technology and software design which is the best lab dissolved oxygen analysis meter with the highest performance and the lowest cost. It is suitable for the trade such as the aquiculture, water monitoring, sewage treatment, and environmental monitoring etc., and also has extensive application in the fields of education and scientific research.
Built-in microprocessor chip, beautiful appearance and convenient operations, this meter has the following prominent features:
1.1. Meter meets with the requirement of international GLP standards. Its features up to automatic calibration, automatic temperature compensation, automatic salinity compensation, automatic air pressure compensation, data storage, clock display, timing measurement, RS-232 output and function setting etc.

1.2. Adopts digital filter and step slipping technology to improve meter’s response speed and result accuracy. “      ” will appear when reading to be stable.
1.3. Equips new type of DO electrode which has function of automatic temperature compensation and automatic salinity compensation as well as automatic air pressure compensation inside meter, which make DO measuring mode has temperature, air pressure and salinity automatic compensation, easy to use, accurate to measure.
1.4. Adopts polarogram type DO electrode has special electrode calibration cap. Only need 3 to 5 minutes for electrode polarization. Electrode adopts combination diaphragm cap, assembling sensitive membrane with diaphragm cap, which very convenient to replace the sensitive membrane. The user only needs to screw the new membrane cap on the electrode. Each DO electrode equips with three spare diaphragms caps.
1.5. Meter’s circuit board adopts SMT film-covering technology to improve meter’s reliability.
1.6. Meter has the only product serial number.
1.7. Dustproof and waterproof meter meets IP54 rating, all sockets are seal protected by the silica gel caps.
