Product Description

Manufacturer: Vaisala

Model: HMI41

Condition: For Parts or Not Working. Comes in non-original packaging. This lot is in Fair cosmetic condition.  There are lots of scuffs/stains and adhesive label residues. There are several heavy scratches. There are several fading/peeling labels.  One of the indicators had dead batteries stored inside and it got all corroded to heck inside the battery compartment. A couple of these parts have rejection stickers from calibration labs but no explanations are listed.  One of the cases has good foam, the other case's foam got gross and was removed.

Note that these will ship without batteries to protect the electronics. The photos show the exact item(s) the buyer will receive.

Notes: These parts are in PARTIAL working condition.  One of the indicators does not power on. Three of them power on. Four of the probes give humidity and temperature indications but they all disagree with each other as well as with our in-house measurement equipment.  We are not sure what-all may be wrong with these parts. No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
