DENSITY / SPECIFIC GRAVITY METER |
|
|
Density measurement of asphalt,
concrete and soil |
|
 |
- Gauge of the surface density of
soils and grounds is intended for measuring of density in a surface
layer at the depth up to 20 cm and is the mean of process and
technical control of surface density of strengthened and non
strengthened soils, of laying of asphalt and cement concrete.
- Can be used in the various systems
of construction quality management, either independently as a mean
of express-control of surface density of soils and concrete or in
the complex with the other devices as a mean of control of strength
and staunchness of concrete.
- A device is proposed to
construction enterprises and laboratories, to services of technical
control and inspection for quick and objective estimation of the
quality of fulfilled construction, hydrotechnical and road works.
- Density meter is a portable device
with autonomous power supply from rechargeable battery.
- The principle of operation is
based on the dependence of the gamma-radiation intensity
back-scattered from the tested medium on medium density.

Specific Gravity Sensor |
|
 |
The
Tech Pro densiTECH
II, automatic specific gravity tester is designed for rapid and accurate
determinations of density. Operation is simplified to allow test rates
of up to 4 tests per minute. Accuracy of the instrument is better than
+/- 0.025%. The densiTECH II utilizes a four decimal place
analytical balance. This balance may be used
separately for other weighing applications.
Density of a solid
sample is determined by the hydro-static method by comparing the weights
of the sample in air and water. The operator simply hangs the sample
from the balance and pushes the start button.
A micro-processor then weighs the sample in air, automatically raises a
beaker of distilled water, take the weight in water and lowers the
beaker. The density is displayed. The weight in air, weight in water,
and the weight difference may also be displayed. The densiTECH II comes
standard with RS232 output and the densiDATA, specific gravity and
volume change software. |
|
The densiDATA software
allows for storage and recall of density measurements and also allows
for the calculation of volume change. Up to 100 volume change readings
can be calculated against the original reading.
The densiTECH II is
automatically calibrated by an internal 100 gram
weight every time the instrument is turned on.

Digital Hydrometer |
|
 |
Battery testing has never been this easy. Simply insert the
nozzle of the digital hydrometer into the battery, depress the finder pump, and
extract a few drops of electrolyte. Touch one button and the processor does the
rest. Within seconds you have an accurate reading of temperature compensated
specific gravity and electrolyte temperature.
Field studies show time savings of at least 5 times (500%) using the SBS-2500
Digital Hydrometer over a standard glass hydrometer and thermometer.
This digital hydrometer will log up to 1,100 individual S.G. &
temperature readings that can later be uploaded to a laptop or PC running the
included software.
Whether in a
telecommunications central office, a utility substation or a critical data power
battery room, the ability to spot check the specific gravity of suspect cells is
invaluable. Performing some or all of your own preventatitve maintenance on
your entire flooded battery plant is greatly simplified when employing this
digital |
