A: Yes, It can.

Does it have to stay plugged into the COMPUTER to be used?

A: No. You do need to set it up initially with the computer software which is very easy. You can only start and stop the recording ONCE. After that, it will need to be connected to a PC to reset. Overall, I found this works very well. You can export the results in PDF WORD and EXCEL format which is handy.


Q: I need to measure the temp and humidity in the basement of a house for a 6 month period. would this product be good for that? can it store 6 mos data?

A: No. It can't read the temperature. You can download the data.


Q: Does it have to be used with an external sensor?

A: No. This has an internal temp and humidity sensor.

Q: How long is the external sensor and is it a probe type?

A: It is the stainless probe. It is about 6".

Q: How do you see the external sensor data? I don't 
see it anywhere in the software.
