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!

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.
