  Using Aranet T/RH Probes: 

  - What is the shortest time interval (or resolution) that readings can be taken?

  - What is the response time to Temp / RH changes?

  Example: For a 1 minute period, how many sample readings can I take? If the RH changes by 20% during this period, how quickly will that change be reflected in the readings?

  Best,

  Hi!
  
  Most of the information is available in the datasheet here:
  https://cdn.bfldr.com/FS48XT6B/at/qrkxpn3tgr23g9q6f6cbhwrc/Aranet_Datasheet_TDSPT309_TRH_probe.pdf
  
  The shortest measurment interval available is 1 minute.
  The response time for Temperature change is 10 minutes and for RH is TBD

  Thank you.  

  Response time is typically change/period so for instance 0.2°c/second or presented as a curve if non-linear.  Do you know what that is for temp?

  Hi!
  
  Sorry, I was looking at the incorrect datasheet before.
  The response time τ for the T and RH is unknown for now. We will see if we can get that value for you.

  Your return policy states that the product must be unused and is limited to US$750. Am I correct then that we cannot purchase a base + two probes, test them to see how well they work, and then return them if they do not perform as we need?
