2701B Non nuclear Density Meter

Introduction: The 2701B nuclear free density meter uses electromagnetic method to measure the uniformity and relative density of asphalt pavement, and automatically calculates the average density, compaction degree, and porosity. This measurement is easy to detect the unevenness, segregation, and low-density areas of asphalt pavement, which is beneficial for solving problems before road repair is completed.

The 2701B coreless density meter, as an ideal asphalt pavement testing equipment, has the following functional characteristics and advantages:
1. Fast measurement speed - display measurement results within 2 seconds
2. The instrument is lightweight
3. 2701B nuclear free densitometer is nuclear free and does not require temperature correction
4. For the convenience of measurement, the compression handle is simplified to a bendable form
5. The transport box contains metal plates used for instrument and factory standard data calibration
6. Advanced testing software provides three measurement modes: continuous measurement, average measurement, and single point measurement
7. Can store 999 measurement data
8. Automatically calculate average density, compaction degree, and porosity
9. The unit of measurement can be metric or imperial
10. The typical lifespan of a battery is 32 hours
11. Fast charging speed, typical time is 1.5 hours
12. Large screen LCD display with backlight: 4 lines, 20 characters per line, 30 keyboards
