It is a small and lightweight dust meter for measuring personal exposure of workers to dust.
The measured value can be displayed by switching between the accumulated count and the instantaneous value.
The measurement range is 1~100,000CPM. (The upper limit of the measurement range, 100,000CPM, is a relative concentration range for capturing instantaneous high concentration peaks, and does not guarantee constant high concentration measurements. The normal concentration range should be 10,000CPM or less. )
Measurement can be recorded in the internal memory by using the data logging function.
Recorded measurement values can be transferred to a personal computer using dedicated software.
