Model 52 classic desktop dissolved oxygen meter

• a popular model with all the functions of dissolved oxygen meter and positioned at medium and low prices, which can be used for laboratory and field tests

• high accuracy: microprocessor control, which is far more accurate than other general models in the market. Automatic temperature compensation: incomparable low compensation error. 0 to 40ppt salinity is directly compensated, and the compensation range covers the whole range from fresh water to sea water

• large LCD: it can simultaneously display air saturation, mg / L dissolved oxygen, temperature and time; Parameters can be read without shifting, which is fast and time-saving.

Simple automatic air calibration: it can be programmed into altitude or atmospheric pressure compensation. Compatible with 5905 probe and 5120 BOD analysis software

• RS232 interface: all functions of the instrument can be directly controlled by the software written by the user

• non volatile flash memory: it can store 70 groups of dissolved oxygen and temperature data, and each group of readings is attached with date, time and geodesic or test number labels; The stored data can be reviewed on the display screen or uploaded to the computer or serial printer; Stored data will not be lost due to power failure

• automatic stability reading function: when the test reading reaches the stability conditions set by the user, the instrument will automatically indicate to ensure the stability of the highest reading
