 Type
323 conforms to measurement law JIS C 1510-1995, and exerts mobility
at every measuring site because of its smallness and light weight.
Combination/Integration with Vibration Pickup Type 7833 allows you
to measure vibration levels floor and vibration acceleration levels
on the ground, floor, foundation and seat etc., simultaneously in three
directions of X, Y and Z.
The measuring and computing items are vibration level Lv
for which sensory characteristics are taken into account,
vibration acceleration level Lva of physical quantity, power
average Leq, maximum value Lmax, minimum value Lmin and Percentile
level Lx, of which instantaneous values are digitally displayed
on the liquid crystal screen.
These can be simultaneously recorded on an external level recorder
with output terminals independent in three directions. In addition,
data processing has been simplified by integrating with peripherals
using I/O terminal (RS-232C interface).
ACO's Sound Meters, Types 6224/6226, having the equivalent specifications,
are also on sale as popular comparison meters. Please make use of these
in combination with the measuring instruments for environment control.
FEATURES:
- Easy to handle as a result of its smallness
and light weight, high mobility and easy operation. Measurer does
not require any special skill. The pickup for measurement offers
compatibility.
- Digital values and bar graphs are displayed
on a large-scale liquid crystal screen equipped with backlight.
Anyone can take a measurement without a reading error, and easily
grasp vibration amounts with the bar graph.
- Wide range of linearity 75dB eliminates switching.
- Maximum and minimum values(Lmax, Lmin), Percentile
vibration level (Lx; five values) and power average are computed
simultaneously in three directions, and selectively displayed.
- Rs-232C interface built-in, data management
and processing can be easily carried out by data management software
(separately sold).
- A wide range of vibration levels can be easily
measured and operability is enhanced by using the tripod stand.
