YANTAI STARK INSTRUMENT CO., LTD.

Display and menu operation: DOG-2092XZ type meter use menu structure, clear, easy operate and use.

Instrument menu: There are three menu selection operation

Multiple parameters simultaneously displayed: oxygen concentration value, the input current or output

current, temperature, and the state indicated on the same screen.

Output current setting and inspection: The output current value can be inspected and set arbitrarily,

convenient for detect and record.

Four calibration methods: One point and two-point calibration method, manually enter the zero point and

slope, and known oxygen concentration calibration methods to meet a variety of situations.
