Just in case you do not know the specs of this thing:
designed for colour and NIST reference calibrated (of course can be used for B&W)
Celsius and Fahrenheit scales (individually calibrated)
12-60oC (54-140oF)
Celsius calibrated (accurate to ±0.125) at 15, 20, 25, 40 and 50oC. Accurate to ±¼oC over the rest of the scale.
Fahrenheit calibrated (accurate to ±0.25) at 59, 68, 77, 86, 104 and 122oF. Accurate to ±½oF over the rest of the scale.
This is a nice piece of equipment for the darkroom. $75 + PayPal + Shipping gets it.
