    Comments about Extech 44550 Humidity/Temperature Pen, 20 to 90% RH/, 14 to 122F:

    As a piano technician, I find this little pen quite handy when discussing the conditions that a customer's piano is under. I use it to sell humidity control systems for pianos. Great little device and quite accurate.

    Bottom Line Yes, I would recommend this to a friend
