DO Probe Optical 10m Cable
Description
The DO810 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.
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 1.4 cm
Comparison Between Electrochemistry DO Sensor and Optical DO Sensor:
| Polarography or Galvanic DO Sensor | Optical DO Sensor | |
| Measurement | Consume oxygen in measurement - Unstable measurements. | Adopts Fluorescence technologies, no oxygen being consumed during test - stable measurements. |
| Calibration | Serious electrode polarisation, frequent calibration is needed; calibration time consuming. | No polarisation; no need to calibrate frequently; only 2 minutes to calibrate. |
| Performance | Slow response, bad repeatability, low accuracy. | 15 seconds response time, good repeatability, high accuracy. |
| Lifetime | Electrode membrane need to be frequently replaced; electrolyte need to be refilled; short life time. | No electrode membrane; no electrolyte; Service live > 8,000 hours. |
