Detailed introduction:

DOS-808 desktop Chinese dissolved oxygen meter (ppm level)


  DOS-808 ppm-level desktop oxygen analyzer is a laboratory ppm-level oxygen content testing instrument produced by RAMZY, which is a highly intelligent continuous monitor. Equipped with DOGSP ppm level polarographic oxygen electrode, it can realize the range measurement in ppm level. It is a special instrument for measuring the oxygen content in the liquid of environmental protection sewage laboratory ppm level water quality.


● Full Chinese display, simple menu structure, text-based dialogue

● Simultaneous display of multiple parameters: Simultaneous display of oxygen concentration value, input current, temperature, time status on one screen.

● Historical data function: Press the storage key in the measurement state, the secondary meter automatically stores the measured oxygen concentration value temperature value

● Four calibration methods: One-point two-point calibration methods, manual input of zero point slope, calibration of known oxygen concentration values to meet the use in various situations.
