SP Scientific XE75 Temperature Cycling System FTS Air-Jet Sample Cooler/Heater A

Manufacturer: FTS Systems

Model: XE753

Condition: Used. This system is in Fair cosmetic condition.  There are lots of small scuffs/scratches/dings especially in the bigger cabinet that make it look a little rough from close up.  The rear panel on your unit may be dented-in.  The place where the air input goes in the machine may be a little bent on the unit you receive, but this does not affect function. Cosmetic appearance may vary slightly from pictured unit(s).

Notes: This unit is in mostly-working condition.  It gets cold and hot, but the temperature transitions are longer than specified by the manufacturer.  Heating times are about 140% as long as they should be.  Cooling times especially are slow, up to triple the rated 20 seconds from +125 to -55 This may be as simple as re-tuning the PID values in the controller, but we are not sure.  The Airflow light does light up, but not all of the units we have give a Refrigeration light.

Please NOTE: the stability of the output temperature was NOT to specification during our testing.  The output bounced around, some units more than others, up to several degrees + and -, but we think this may also be a sign that the controller needs to be tuned. No manuals, cords/cables, or additional items are included if not listed or shown.
