Microsecond Timer
Microsecond Timer is a high precision tool which measures sound transit time in trees and wood, which helps determining the structural integrity of the material. The sensors can be used under-water.
- Measures the transit time in microseconds
- Determines the stress-wave velocity
- Helps estimating the modulus of elasticity
- Quick operation: several 100 trees can be measured in a single day
- Detects the bigger decays, holes in trees
This product was designed to reveal the internal structure of trees, which is invisible to the naked eye, in order to detect damage and cavities. The instrument measures the time it takes for a sound wave to travel. The signal is generated by a hammer strike on the START sensor, and the instrument measures the transmission time between the START and the STOP sensor. Knowing the distance between the two sensors, the velocity of the signal can be calculated, and conclusions can be drawn about the condition of the tree.
Connect the sensors to the timer box.
Switch on the timer. A new measurement is displayed each time you hit the START sensor.
Sensors are identical. Please select the sensor, connected to the „Start” connector. A color mark helps you to identify the start sensor. Hit the start sensor using hammer. The hit should always be parallel with the direction of the nail. Use a rubber hammer for driving in the sensors. For the measurement use a 100 g steel hammer. Let the hammer spring back. After use, switch off the unit.
