Horiba CS-151F1-0105-AA-QU-P-5M Chemical Solution Concentration Monitor CS-100

Current Stock:

Product Description

Manufacturer: Horiba

Model: CS-151F1-0105-AA-QU-P-5M

Condition: Used. Comes in non-original packaging.  This unit is in Good cosmetic condition with only minor blemishes from prior use.  There are some big chips/scratches in the paint, mostly along the edges. The screws to secure fibers are non-standard allen screws but still works fine.  The Pt Sensor terminal screws are missing. Cosmetic appearance may vary slightly from pictured unit(s).

Notes: This monitor powers on and the display gives readings of 0% for everything.  Pressing the up/down button changes the display as expected.  A light can be seen behind a shield on the front of the machine as well as one of the fiber connection holes.  The fan is a bit loud but still runs.  With nothing else hooked up (as shown) the monitor first calls out E001 and when left to sit for a few minutes the display blinks and says E201.  We are not sure if this is normal.  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
