Why buy an expensive oxygen meter when you can buy an oxygen probe which works with any standard pH meter, chart recorder, or PC?
Consider these unique features:
  • Plugs directly into any pH meter-reads out directly in ppm or %O2
  • 1/3 to 1/2 the cost of a complete oxygen meter
  • Useful in all lab applications including BOD measurements
  • Fully portable for oxygen measurements in the field
  • Micro O2 electrode available for measurements down to 20 microliters
  • Fast response time- less than 12 seconds
  • More accurate and less tedious than Winkler method
Cat. No.: DO-166-4L

Description: This dissolved oxygen probe comes complete with its own preamplifier circuit so that it can be used directly with most pH/millivolt meters, strip chart recorders, and a PC which has an A/D converter. The standard probe comes with a 4 ft. cable (1.2 meter) and can be used for both field and lab work.

  • USE WITH ANY pH METER. Probe can be plugged directly into any standard pH meter for dissolved oxygen measurements.
  • USE WITH PC COMPUTER. Use with Lazar low cost datalogger for monitoring and recording with your PC.
  • COVERS FULL DO RANGE. Electrode can measure dissolved oxygen from 0 to 20 ppm or 0 to 150% saturation.
  • ELIMINATES WINKLER METHOD. Probe measures dissolved oxygen directly without involved wet chemistry of titrations needed with the Winkler method.
  • BOD MEASUREMENTS. BOD probe fits directly into BOD bottle for 5 day or continuous BOD measurements.
  • PORTABLE. On-the-spot field measurements of dissolved oxygen can be made without a trip back to the laboratory.
  • RAPID RESPONSE. Typical response time at room temperature is 12 seconds.

Applications:Applications include measurements in potable water and wastewater, environmental analysis of lakes, streams, and rivers, and BOD determinations.
