Density
The density of paint will depend on their ingredients in the paint. Density is also known as specific gravity or mass per unit volume.The more ingredients/particles in paint the more mass per unit of volume. This is called density (S.G) can be written as g/cm3. The reference substance for liquids is nearly always water. It is important to specify temperature for both the sample and reference. To find the density of a paint you need to establish the weight of the product. For these several instruments are available, pyknometers, immersion bodies, densimeters and weighing scales.

Weighing Instruments
ZhangZhou Weihua Electronic co.,ltd
are devices to measure weight or calculate mass. Spring balances or spring scales measure force (weight) by balancing the weight due to gravity against the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of a known mass or masses. Either type can be calibrated to read in units of force (weight) such as newtons, or in units of mass such as kilograms, but the balance or pair of scales using a traditional balance beam to compare masses will read correctly for mass even if moved to a place with a different (non-zero) gravitational field strength (but would then not read correctly if calibrated in units of force), while the spring balance would read correctly in force in a different gravitational field strength (but would not read correctly if calibrated in units of mass).

Battery Voltage Recorder
BVR Series
Battery voltage recorders from BVR series are designed to serve as a support tool for cell voltage measurement during battery capacity testing.During capacity testing, cell voltage, temperature, inter-cell connection voltage, and specific gravity should be measured in order to determine failling cells in the string that should be replaced.Furthermore, IEEE standards for stationary batteries applications stipulate periodical measurement of overall string voltage, as well as cell voltage and temperature.The BVR Series is the perfect tool for that purpose. All measurements are automatically saved in device’s internal memory. Additionally, DV-B Win software helps the user to download all measured results. Furthermore, the user can create test reports and export them to various formats.BVR series includes two models: BVR11 and BVR22. These are rechargeable handheld devices intended for performing monthly battery inspections and support tools during capacity testing. The list of the applications of these instruments includes:Efficient supplement to BLU series of battery load units during battery discharge testingMonthly inspections of large battery banksAmbient temperature measurementCurrent measurement using current clampsUSB and Bluetooth communication with PCSimultaneous string voltage and current measurement to analyze a discharge test processThe BVR22 model provides Bluetooth communication with an external density meter, for transferring electrolyte specific gravity and temperature readings.

Dynamic Calibration for ROSS Streak Cameras
DynaCal
The DynaCal Optical Calibration Module (OCM) is designed exclusively for the Sydor ROSS Streak Camera to ensure accuracy, both over time and in situ, so you can be confident that the data from your shot is certified to be correlated to the calibration of your camera. The beauty of in situ calibration is that the cost of removing and resetting the camera is avoided—and so is the risk of the replacement of the camera and shifting or disturbing the sensitive nature of streak camera results. Only in situ calibration will reveal the real world effects of EMR, gravity, electronic noise and more when they distort your camera results.

Density & Specific Gravity
To maintain consistency of a coating, the Density should remain constant from batch to batch. Density Cups, also known as Specific Gravity Cups or Picnometers, are used to determine the mass per unit volume (Specific Gravity) of a liquid at a given temperature. Specific Gravity is defined as the ratio of the density of a given substance to the density of water, when both are at the same temperature. As the Specific Gravity Cup is an exact measurement of the volume of the liquid, it is imperative that the exact weight of the sample is obtained.
