MCS-1

 
Moisture content standards are great for verifying that your Delmhorst moisture meter is in calibration. The MCS-1 can be used on any meter with a wood scale. With two electrical resistance values (12% and 22%) to test your meter against, you can be sure that your readings will stand up to the strictest standards of accuracy.
 
The MCS-1 is also available with a letter of certification traceable to NIST (calculate a 2 weeks delay).
