[CAUT] FW: Temperature/Humidity range

[Don]

Hi Mark,

What are your "tolerances" for A4? If they are 4 cents or less then
adequate humidity and temperature control has to be within 5%. Possible to
do but ultra expenses via HVAC

Your Radio shack device is very inaccurate at the extreme ends of its
range. Probably about + or - 10% at a 20% reading.
