CBR/LBR TEST MONITOR – DMP-12A
GPE, inc. introduces the CBR/LBR Test Monitor, Model DMP-12A. The
DMP-12A was developed to supplement CBR/LBR test equipment available from other
manufacturers (Rainhart, Gilson, etc.).
The DMP-12A provides automated data acquisition, storage, processing and test control. Its
microprocessor-based design permits computed, consistent, and accurate CBR & LBR
values for every sample.
