James Instrument Humitest System measures bore hole humidity in hardened concrete, according to the manufacturer. The product allows the concrete practitioner to monitor and ensure that a new structure is dry enough to start the next phase of construction. This is especially critical for concrete structures requiring a coating, carpeting or similar floor or covering treatment.

The James D-W-2000 digital test hammers are an automated system for estimating concrete compressive strength. Its calculation, memory and recording functions allow for quick, easy and accurate test results. The unit comes with an integrated alphanumeric digital display and control panel.

Capital Safety has developed an easy way to track fall-protection gear with its new "i-Safe" radio tag system. Made from the same rugged tags that farmers use to track livestock, the poker chip-sized buttons come sewn inside all new DBI-SALA harnesses starting this year at no extra cost. Tags also can be retrofitted onto older pieces of fall protection gear, including off-brand harnesses. Users will need to buy a special PDA costing $700 to scan and track the tags. One scanned, users can manage their fall-protection assets at a secured Internet-based portal at no extra cost. The tags, which require no batteries, can also help users prevent theft, document safety inspections and manage regulatory compliance. Capital Safety; 651-388-8282; www.capitalsafety.com
