Product Description

Manufacturer: Tenney

Model: TUJR

Condition: Used. Comes in non-original packaging. This chamber is in Good cosmetic condition overall, but there are a few places where there are heavy scuffs/scratches/shallow dents outside.  These do not affect function.  The viewing window is cloudy and has visible condensation between the panes.  Inside, the chamber looks pretty clean with only minor deposits from prior use. The photos show the exact item(s) the buyer will receive.

Notes: This chamber is in Good working condition.  We verified it can control its own temperature well from -75º to +170º.  The interior fan runs quietly, and the compressors are also fairly quiet.  It took about an hour to go from -75º to +166º, and the last degree took a long time, about an hour to stabilize from 170.2 to 170.  From +170º to -50º took about 45 minutes, and once again the last degree took a long time to settle in once it got close to -75º.  We think the slow final stabilization is probably a matter of tuning.  Temperature transitions were faster than the specification for the most part, and when the controller was set to the minimum possible of -85º the temperature indication got as low as -80º.  Operation in manual mode was very straightforward (push an arrow button to change the setpoint).  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
