For short term and long term monitoring.
The Memo-Chip BL2 module can save moisture, relative humidity and temperature measurements in preset time intervals. Measurements are downloaded when connected to a PC. In order to function as a data logger, one of the following devices has to be connected:
- RH Thermo-Hygro probe for measuring RH / Temp / DPT / GPP / EMC.
- Tracker MC/RH module for measuring RH / Temp / DPT / GPP / EMC plus moisture of wood and other solid materials.
A free application can be downloaded from the Lignomat web-site to set up the BL2 for monitoring at desired time intervals between 30 seconds and 24 hours, saving a total of 32 000 data sets. Out of range values for humidity and temperature can be preset. Multi colored LED lights are built-in to warn of out-of-range values and serve as performance indicators. An audible alarm is also selectable to indicate out of range values.
The Memo-Chip does not have an internal relative humidity probe built-in. Any RH probe from Lignomat can be connected with the RH adapter or RH cable. If you already have an RH probe with RH Adapter for your handheld meter from Lignomat, the same RH Probe can be plugged into the BL2 Memo-Chip to obtain measurements.
Another advantage of the external RH probe is, that the probe and cable can be left in place, while the BL2 is dis-connected to review data on the PC. After re-connecting the BL2 to the RH cable and RH probe, recording will proceed automatically adding measurements to the same log or a new log can be started. Example, measuring moisture conditions inside a wall, while insulation is being dried out.
The Memo-Chip BL2 has two connectors built-in and 4 multi-colored LED indicator lights.
On the other end, a USB connector for a USB cable to download measurements to a PC. While recording, the USB cable is not connected to the BL2.
The multi-colored LED lights indicate, when measurements are above or below the preset range. The lights also indicate the function the BL2 is performing. For instance, when you connect the RH BluePeg probe, a blue LED indicates that the system now starts to record.
When the BL2 is set up with minimum and maximum permissible values, the red LED will be on for out of range values. You also have a choice whether or not to sound an audible alarm.
The RH Thermo-Hygro probe (standard RH BluePeg probe with RH adapter) is added to measure ambient conditions of humidity and temperature. The RH BluePeg probe comes with a precision, reliable, fast-responding RH/T sensing element. Adding the RH cable allows for in-wall, in-depth monitoring. Standard cable length is 6 ft, we custom make RH cables (stereo cables) for any length up to 75 ft.
