The Ligno-Tec RH meter functions as an RH meter or a thermo-hygrometer, when the RH BluePeg probe is connected. The RH BluePeg probe uses a single micro-chip sensing element, factory calibrated to NIST standard. The sensing elements were chosen for their precision and fast response time. The RH probe is detachable.
- The Ligno-Tec RH meter measures and indicates:
- RH: relative humidity
- Temp: ambient temperature
- GPP: grains per pound
- DewP: dew point temperature
- RH probes have individual 3-digit numbers
For extended reach, the probe can be connected with a stereo cable up to 50ft long. The Ligno-Tec RH meter, reusable RH BluePeg Probes, sleeves and cable are designed to comply with latest ASTM F2170 standard for a simple and fail-proof concrete moisture testing procedure.
The Ligno-Tec RH meter has a 3.5mm stereo connector (jack) mounted in the top of the meter, where the RH probe has to be connected. The connection is made via the optional RH Adapter or the RH Cable for remote measurements. If the reach of the probe has to be extended further, longer cables are available. The RH depth adapter can be used to extend the length of the RH probe.
