Lignomat’s Unique Design for Taking Measurements Using ASTM F-2170

The RH BluePeg uses a single microchip, factory calibrated to NIST Standards. Each BluePeg comes with a NIST traceable certificate. The RH BluePeg probes comply with the latest ASTM F2170.

For the first year, Lignomat offers to check the probe calibration at no charge. For sensitive tests, the calibration of the removable probes could be checked after the test. We also sell a salt solution for the RH BluePeg probe which can be purchased for $49.00. The salt solution allows for easy calibration that can be done in-house over and over again.

Good Seal, Easier to Place Sleeves

Lignomat’s sleeves have feathered fins along their entire length, which provide an excellent seal. The lip of the sleeve covers the area around the concrete hole and provides another barrier for any air escaping. At the bottom of the sleeve is a movable cylinder, which places the RH probe every time as required by the ASTM F2170. Standard sleeves require no cutting. 3″ long sleeves are available. We also have top extenders that can be used when measuring gyp-crete.

Better Sealing, Flatter Caps

Lignomat’s caps come with an o-ring to absolutely seal the sleeves. The caps are flat and do not interfere with any traffic around the test area. We supply red caps to easily spot the sleeve with a RH BluePeg sensor.

Fast Connection

A fail-proof, easy-connect 35 mm stereo plug is used to connect RH probes. No twisting, turning or setting-up an instrument for readings. No pin arrangements need to be fitted.

Most Accurate Testing

Our meter instantly shows the RH and temperature values. The resolution on Lignomat’s meter is 0.1%. No guessing or rounding up.
