The DO803 Luminescent Optical DO Probe is the replacement optical DO probe for Apera DO850 and DO8500 Portable Optical DO meters. The probe adopts state-of-the-art optical DO sensor, which has significant advantages compared to the traditional galvanic/polarographic probes.
DO803 Luminescent Optical DO Probe
Effortless Operation
The Optical DO probe does not consume oxygen in the liquid, hence there is no requirement for water flowing speed. Just insert the probe in the liquid, and get the readings when it's stable -- as simple as measuring pH.
Quick Stable Reading
It takes only 1 to 3 minutes for reading stabilization. Frequent calibration is not necessary. Calibration only takes 1-2 minutes.
Diameter of the probe for: approximately 0.55 inches (1.4 cm)
