DO850 Portable Dissolved Oxygen Meter Kit

AI480


The APERA Instruments DO850 Dissolved Oxygen Meter is equipped with ultramodern optical sensor for dissolved oxygen measurements. Equipped with state-of-the-art Optical DO sensor: measures dissolved oxygen level in a RELIABLE and EFFORTLESS manner

Minimal maintenance required. Easy calibration

State of the art Luminescent Optical DO Sensor

  • No Membrane, No Solution, No Hassle.
  • Quick & Accurate Measurements
  • The probe does not consume oxygen. No limit on water flowing speed.
  • Maintenance-free. No need to calibrate before every use.
  • The service life of the luminescent cap is over 8000 hours. No need to replace the cap every year.
  • The special coating on the luminescent cap makes it anti-interference and unaffected by light and chemicals.
  • A calibration cap comes with the probe, which allows it to be calibrated and stored in saturated air.

Intelligent Instrumentation

  • Auto Temperature Compensation; Auto Air Pressure (barometric) Compensation; Manual Salinity Compensation
  • Large backlit LCD screen, simultaneously displaying dissolved oxygen reading and temperature. Easy switch from mg/L and % to ppm and %.
  • Advanced digital processing technology, supporting stable reading and auto-lock display modes.
  • IP57 Waterproof dust-proof rating allows the meter to be used in harsh environments.
  • Foldable stand allows use as a benchtop meter.
  • Comes with a rugged carrying case, which includes a meter, an optical DO probe, and the accessories.
  • 3-Year warranty with the instrument, 2-year with the probe.
