Darwin Chambers PH09-DA 9 Cu.Ft. Stability Temp/Humidity Environmental Chamber

Manufacturer: Darwin Chambers

Model: PH09-DA

Condition: Used. This chamber is in good cosmetic condition, with only minor residues from prior use, as well as some scratches on the door.
Cosmetic appearance may vary slightly from pictured unit(s).

Notes: This chamber is in good working condition.  We were able to verify temperature control from 20º to 50º (the limits of the set point range).  Cooling and heating rates were slow, and the temperature controller alarmed a couple of times on the way from 20 to 50, but we think this is 'normal' for small peltier heaters in such a large space.  We were able to verify operation from 90% to 35% humidity (our air supply is not very dry).  The fans all work.  The controls respond as expected to user inputs, and the displays are bright and easy to read.  The alarm-silence button works.  The casters roll easily, but not as smoothly as we would like.  Note that during a couple of hours at maximum temperature/humidity, a small puddle came from the bottom of the door - the entire door seal was wet on bottom, and there was condensate in the rear drain line as well.  No other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
