Introduction (Continued)
DENSITY4/5 Introduction
The DENSITY4/5 is the new density meter available from Reichert and designed for fast and reliable
measurement of relative density and concentration of fluid samples. It is designed for continuous density
measurement in a broad range of applications and has a sealed measurement system with the flexibility
to measure the density for many fluids.
The Reichert DENSITY4/5 insures a consistent manufacturing process for you and allows tighter toleranc-
es on the results, reducing costs and increasing the quality approvals. For performance and quality choose
the Reichert DENSITY4/5.
Reichert introduces the DENSITY4/5 based on the well known principle of the oscillating tube sensor. High
precision and reproducibility combined with simple and error free operation classifies the DENSITY4/5 in
the field of high performance density meters.
The DENSITY4/5 is manufactured according to the worldwide known Reichert quality, where the unit is
fully tested and manufactured for long life and durability. This instrument is compatible with many different
reference alcohol tables, has very good precision density resolution, and can be used with a wide range of
fluids that will solve the most challenging applications. In addition, this instrument has a built-in moisture
sensor, an air pressure sensor and a very accurate temperature control system for extended usage in diffi-
cult environmental conditions. Intuitive user friendly software with a large color-TFT touchscreen interface
reduces the setup times for protocols and adds powerful troubleshooting capabilities.
Common accessories and robust exchangeable fittings reduce installation expense and saves times to
evaluate 3rd party fluids. The DENSITY4/5 can be combined with other Reichert instruments, such re-
fractometers, which allow this instrument to be used for complex analysis. This unique modular capability
combined with advanced electronics design sets a new standard for density measurement and makes it
possible for a quick and easy, on-site change of the measuring cell possible.
Definition of Density
DENSITY4/5 is a characteristic feature of all substances and is defined as mass per unit volume:
p= m
V
___ p = density
m = mass
V = volume
In general: The volume of gases, liquids and solids depend on temperature and pressure!
Most substances expand with increasing temperature, but density decreases with increasing temperature
(example: Mercury-Thermometer).
Note: It makes a difference whether you measure the mass of an object in air or in vacuum:
 Weightmeasuredinvacuum→“TrueDensity”(Truedensityofair:1.2kg/m³)
 Weightmeasuredinair→“ApparentDensity”(Apparentdensityofair:0kg/m³)

Oscillating U-Tube
The DENSITY4/5 has a built-in reference oscillating U-Tube, which is a new method of measuring density.
Approximately 1.0 ml of sample is needed for a measurement and the device offers very high accuracy
and resolution. Working with an oscillating U-Tube is ultra fast compared to other methods and true density
is provided in the measurement. the system is fully automatic (calculations not necessary), so it is less
vulnerable to human error.
The oscillating U-tube samples the viscosity of a fluid by vibrating a glass tube at a frequency which will
measure the resistance of a fluid that is being deformed by either shear stress or tensional stress. This
sometimesisreferredtoasthe“thickness”ofafluidandithasthefollowingparameters:
• Highviscosity→densityover-reading
• Lowviscosity→correctresult
Another parameter to consider in the measurement process is the temperature of the fluid. The tem-
perature of the fluid is very important. The built-in high accuracy temperature sensor guarantees precise
measurement utilizing a Peltier-Element (temperature range 5°C to 95°C) to control the fluid temperature.
Some features of the temperature control system are:
• Eliminates temperature drift. After modifying the measuring temperature, the instrument
remains stable as soon as the new temperature is reached.
• Simpliesmeasurementatdifferentmeasuringtemperatures.Using the temperature con-
trol at 20 °C provides consistent data related to one temperature.
(additional adjustment at 40 °C and 60 °C can be performed. for example, once a year to re-adjust tem-
perature characteristics of the DENSITY4/5 sensor).

Setting Up the DENSITY4/5
Connecting DENSITY4/5 to power supply
• Connect the power cord to an electrical socket which has the power requirements as indicated on the
data plate of the DENSITY4/5.
• Connect the power cord to the AC Input connector on the back of the DENSITY4/5.
• Turn the device ON by switching the toggle switch (Power Button) to the ON position.
Connecting Air Cartridge
Use the screws provided and align and attach the two metal clips provided onto the back side of the DEN-
SITY4/5 to accept the Air Cartridge. Remove the Air Cartridge from its shipping bag and install it between
the two clips to secure it on the back of the DENSITY4/5.
