Insert the needle probe directly into tissue samples
for oxygen concentration measurements in various kinds
of tissues including various plant and animal
tissues and cell cultures.
The pO2 needle probe is now available as a complete
system which measures, plots and graphs all-in-one. Complete system
includes pO2 needle probe, amplifier, dissolved oxygen
monitor and software which logs and plots directly to your PC. See
DO systems index for full further information.

Use with any pH meter. The needle pO2 electrode utilizes a
self contained amplifier circuit which makes it useable with
any standard pH/mV meter for dissolved oxygen measurements.
The pO2 needle probe can be plugged directly into any pH meter
and is available with all standard pH meter connectors
including BNC, U.S. standard, Radiometer(R), and Metrohm (R).
Use with Chart Recorder. Output voltage of 0 to 2 volts DC
allows connection to any standard chart recorder for
continuous monitoring of pO2 level.
Porlagraphic Principle. pO2 needle probe works on polarographic
principle where oxygen is reduced at a tiny cathode sensor housed
inside a hypodermic needle.
pO2 Depth Profiles. Determine pO2 as a function of tissue
Small Sensor Size. The pO2 needle diameter is 16 gauge.
Long Needle Length. Needle length is 38 mm giving it ample
size to insert into thick tissue samples.
Calibrate in Convenient Units. The micro pO2 probe can be
calibrated in mm Hg pO2 partial pressure, % oxygen, or ppm
Broad pO2 Concentration Range. The micro pO2 has a range from
0 to 100% oxygen or 0 to 760 mm Hg pO2 partial pressure.
Low O2 Detection Limit. The micro pO2 has a detection limit of
1 mm Hg pO2 partial pressure.
Broad Temperature Range. Temperature range is 0 to 50 oC.
