MEASURING ROOM DIMENSIONS using the Zircon DM S40 Sonic Measure
The sonic measure is a device that is used to measure distances quickly and easily. For this study the measuring device will be used to determine the length, width and height of the room where air monitoring is being performed.
This protocol refers specifically to the Zircon DM S40 Sonic Measure but any similar sonic measuring device may be used.
If you choose to use a sonic measuring device with a laser-guide, it is best to somehow cover the laser. The laser has nothing to do with taking measurements and may draw unnecessary attention.
How to use a sonic measuring device:
Turn the device to the "on" position.
Point the device at a solid surface to take a reading.
Press the READ button and hold the device still until the unit displays a reading.
In this case the device is pointed at the ceiling and measurements read 3 feet 7 inches to the ceiling.
You can switch between measuring in feet and meters by pressing the ft/m button.
