  • 1.  Reliable Temperature and Humidity readers

    Posted 02-21-2020 11:16 AM

    Hello all,

     

    My institution has traditionally used HOBO dataloggers but are looking to see what other Museums are using for tracking temperature and humidity with digital logging equipment.  Which models are you all using and which do find them reliable and cost effective?

     

    Thanks for your feedback!

     

    Best,

    Hi Kristy, 

    We use HOBO, T&D and recently Wireless Sensor Tags. T&D has sensors that are either wireless or hooked up directly to ethernet. They are a bit pricier but reliable, send alerts, and can be viewed live from your account on their website. Graphs can also be viewed and downloaded from the site, and don't write over. Wireless Sensor Loggers are super small and affordable, and also take light readings. They are not great for long range but work fine in short range. The good thing about these is that the readings are saved on the Cloud so you can view an entire continuous reading for each Tag! I think T&D is better for long term monitoring and the Tags for short term projects. Both can be easily recalibrated onsite, which we try to do annually.

    I monitor and analyze T/RH data from twenty four historic sites and adjunct properties around MN with over sixty data loggers.  Our primary logger is the PEM 2 from the Image Permanence Institute with eCNB as the data management and analysis tool.  
    Over the past five years, I've incorporated HOBO loggers into the program for 'special' locations such as our State Capitol building,  a pipe organ cabinet and a lighthouse tower where easy access is an issue.  For regular building environments, the MX1101 wireless T/RH loggers work well.  They are half the cost of the PEM2 and are accessible via Bluetooth.  For harsher environments like the lighthouse (i.e. condensing environments), I've put in MX2301 loggers since they are made for outdoor conditions.
    Recently, I've installed the MX2202 "Pendant" T/Light intensity loggers at two sites to monitor light levels on paintings and textile object displays.  Those loggers are around $50/ea., so that's very affordable.  We can easily calculate Lux/hours of exposure to inform rotations schedules with continuous data without having to rely on expensive light logging hardware and complicated software programs as we did in the past.
    Onset Computer Corp. also has webinars that I've found to be helpful.
