and this is my second one. It’s pretty accurate yet easy to
carry. I tune periodically at our large museum and they have some
very accurate and expensive graphing hygrometers in several places in the
museum. I’ll compare my reading to theirs when I’m there and
when it differs significantly I’ll get a new one. They all drift
and need to be either replaced or recalibrated. On this one,
recalibrating is more expensive than buying a new one so I just replace it.<o:p></o:p></span></p>

<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hi List,</span>
<br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I have a couple
of those cheap max-min thermo-hygro readers from Pianotek. I'm not
sure if they're very accurate. If you all remember, last fall/winter I
sent in some photos of one of our recital rooms that Richard West took before I
got here with the fog and water dripping all over everything. It hasn't
been that bad since I've been here, but the last couple of times I've gone in
there this past week, it feels really muggy, but the hygrometer only registers
40-45% (which would be ideal). Any suggestions on who makes a real
accurate reader?</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Thanks</span> <br>
