About Us


On February 1, 1999, our Nuclear Density/Moisture Gauge sales, service, and training facility was opened in Sheboygan, Wisconsin.  Our facility provides training, calibration, and repair of CPN, Instrotek, Troxler, and Humboldt gauges. 


As an authorized CPN and Instrotek sales facility, we offer a full line of CPN and Instrotek gauges.  For those who aren’t familiar with CPN and Instrotek gauges, be assured they are competitively priced, very reliable, and built to last.  In numerous state-sponsored head to head studies, CPN and Instrotek gauges have outperformed the others in both precision and accuracy on asphalt and performed equally well on soils. 


We bring years of experience in repair and calibration of gauges - be it as a service technician for CPN and Instrotek or Troxler or as a Corporate RSO for a large engineering/consulting firm.  Combined, our technical knowledge, RSO and management experience provide a unique insight to gauge operation, repair, calibration, licensing, fiscal, and any client issues associated with your gauge program.  We fully understand how important it is to provide you with a cost-effective and reliable gauge that is going to perform well in the field. 


Our calibrations meet all ASTM and AASHTO requirements and include routine cleaning and maintenance of the gauge.  We are excited about providing you with SUPERIOR CUSTOMER SERVICE and doing whatever it takes to assist you in getting the most out of your gauge program! 

Committed to providing quality calibration, training,
and service of CPN/INSTROTEK, Humboldt,
and Troxler Nuclear Density/Moisture Gauges.
