Apera Instruments AI4101 Optical Dissolved Oxygen Probe with 3-Meter Cable

Features:

• 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.
• 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 to get fully stabilized. Frequent calibration is not necessary. Calibration only takes 1-2 minutes
• Virtually No Maintenance
• There is no electrolytes to replenish; no cathodes and anodes to clean.
• Optical DO Probes
  • Measurement: Adopts luminescent technologies. No oxygen being consumed during test - readings get stabilized quickly.
  • Calibration: No polarization. No need to calibrate frequently.
  • Maintenance: No electrolytes to replenish; No cathodes and anodes to clean.
  • Performance: Fast response, good repeatability, high accuracy.
  • Lifetime: The replaceable membrane cap's service life >8000 hours
