Temperature & Humidity USB Data-Logger

Too bad they are not compatible with Macs:

*Only Compatible with PC Computers (Not Mac)

Anybody know what kind of battery it takes?

Per the features: Battery Operated: 1 x 3.6V Battery.

I was hoping for more info than that. That seems like it could be an oddball battery.

Thanks.

NIST-traceable calibration? Without that, it’s not going to pass an ISO audit in the workplace.

Probably 1/2AA, not too obscure.

I went a ahead and bought one and it was delivered the next day.

And yes, it is a 1/2 AA battery.
