Tenney Jr Environmental Test Chamber -73/+200ºC Watlow F4 Digital 115V 1phase

Manufacturer: Tenney Engineering

Model: Tenney Jr.

Condition: Used. This chamber is in Fair cosmetic condition.  There are many scuffs/scratches/minor dings, and several places with stubborn adhesive tape and label residues outside.  The inside looks pretty clean, but there is something in there that baked off and smoked at very high temperatures during our testing.  The controller was upgraded to an F4, and the control panel is a little DIY-looking but works well.  The back/bottom of the enclosure has a line of paint separation and rust all across the width.  A few cover holes don't line up and are missing screws.
The photos show the exact item(s) the buyer will receive.

Notes: This chamber is in Good working condition, with a couple of important caveats.  We tested to 200ºC and found it was pretty stinky at very high temperatures.  When the door was opened at 200º, a cloud of smoke or vapor billowed out, along with a stronger smell.  We tested to -73º and found that the side port must be plugged in order to get below 63º.  Cooling from 26 (ambient) to -40º took about 20 minutes.  Otherwise, the refrigeration, controller, and internal fan worked as expected.  No other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
