Equipment and Calibration History

History for Vaisala HMP155 T2820180

Rec No.	Date	Loc From	Title	Loc To	Notes
6557	2024-01-25	Factory none	Disposed	Disposed none	Campbell's evaluation: Inspected. Cap filter is dirty and sticker labels started to peel off suggesting sensor has been deployed in a very humid environment. After tests sensor showed problems to provide correct RH and Temp data. Unfortunately sensor can't be repaired or calibrated. Warranty expired o 08-27-2022. NOTE: We suggest to acquire a new unit such as the HygroVUE10, which offers advantages worth look up, as a replacement for the damaged one. Dead unit will be returned so that I can take it apart!
6556	2024-01-17	Lab none	Shipped	Factory none	Sent to Campbell on RMA 37957. RH and AirT are reading zero.
6485	2023-12-08	Mayberry RH & Temp	Removed	Lab none	Removed from the Mayberry tower and brought back to the lab for testing. It was reading -79 deg C and 0% RH.
5673	2021-11-23	Lab none	Installed	Mayberry RH & Temp	Installed on the MB tower to replace HMP45 sn U2120013 which was drifting. It was installed with a new shield and aspirated with a 12V fan. The cable on this sensor says "sn T2820183", which is different than the actual sn of the sensor, so I crossed out sn on the cable to avoid confusion.
