Bio-Tek Instruments Percent Oxygen Monitor Model 74223 (OS)
w/ Manual & Extras
I am largely unfamiliar with the Bio-Tek 74223 Oxygen Monitor. Therefore I have created the
VIDEO
and link below showing the limited testing.  The unit powers up, power indicator light comes on, dials turn freely, and the screen display is bright and clear.  No other testing was done. The unit may have abrasions or scratches.  It is being SOLD AS IS.
Includes:
Oxygen Monitor
(Model 74223)
Original Blue Carrying
Case.
It is in very good condition.  The close clasps still function as designed.  The foam padding is original and still doing its protective function.
Some type of
Cable
that attaches to the unit with a cylinder shaped component on the end with a couple of short clear tubes attached.  Please note, as shown in the 11th photo, there is some electrical tape wrapped on the cable of one end.
A light colored box that contains (3)
Three
sealed
bags that each contain one Cell,
and
small instruction cards (see photos #1, 10, 11, 12)
A couple Black
Fittings
.  One is appears to be an adapter with one threaded end that can be pulled apart to two different peices, and the other is T type fitting with an attached removable cap (see photos 1, 11, and 12)
Operators Manual
(see photos 2 & 8)
Please see the video and pictures. What you see is what you will receive - nothing more or less.
