True Density
Densi 100

● Automated gas pycnometry for precise material characterization.
● Rapid true density measurement ensuring accurate and consistent results.
● Compact design, easy operation for efficient daily laboratory use.

True density is a critical physical property for solid materials—especially powders—affecting everything from product performance to quality control. True density reflects a material’s purity and structural compactness, both of which play a direct role in its end-use properties.

Traditionally, density has been measured using Archimedes’ water displacement method. However, this approach suffers from manual error, liquid drainage issues, and poor repeatability. In response, the International Organization for Standardization (ISO) adopted the gas displacement method (ISO 12154) as the official standard for true density measurement in 2014.

The Densi 100 True Density Analyzer quickly and accurately determines the true volume and true density of a wide range of solid materials, including powders, granules, and solid blocks. With a sample chamber volume range of 1 cm³ to 100 cm³, the system accommodates both small and large samples. Each analysis is completed in approximately 3 minutes, delivering reliable results without compromising accuracy.

 TEST GAS: Helium or Nitrogen
 Characteristic: Non-Destructive
 Resolution: 0.0001 g/ml
 Repeatability: +/- 1%

Key Features

Integrated Testing Module
The Densi 100 combines the sample chamber,expansion chamber,pressuresensor,and control valve into a single,compact unit,ensuring uniform system temperature and enhanced measurement stability.This integrated design delivers exceptional performance,achieving true density accuracy of up to ±0.03% and repeatability better than±0.02%,makingit ideal for both high-precision research and routine quality control applications.

Reference Material
The standard reference material used for calibration is made from nonexpanded alloy and is certified by the National Institute of Metrology, China. This ensures traceability and high confidence in measurement accuracy, with volume precision up to 10⁻⁴ cc.

Multiple Sample Chambers and Inserts
Various chamber and sample cell inserts are available, allowing users to optimize measurement accuracy and accommodate different sample volumes with precision and flexibility.

Density Measurement
The Densi 100 Automatic True Density Analyzer accurately measures the true density of powders within a pressure range of 1 to 1.3 bar.

Unique Design
The Densi 100 is equipped with a built-in processor and Windows-based operating system, enabling fully independent operation without requiring an external computer. Its intelligent self-diagnostic program automatically performs seal integrity verification, reducing operator errors and ensuring consistent, highquality test results.

Pressure Sensor
The Densi 100, equipped with a 2 bar (F.S.) pressure sensor, delivers highly stable and accurate true density measurements. The sensor’s nonlinearity is better than ±0.2%, ensuring precise pressure readings and reliable data capture throughout the testing process.

Software

The Densi 100 offers an intuitive, fully automated testing process, completing measurements in approximately three minutes. Users can customize the number of repeat tests, while all test data is automatically recorded, saved in TXT format, and easily exported via USB.

The system includes PC compatible software for generating and printing comprehensive standard test reports, ensuring seamless data management and documentation.

To enhance versatility, the software features five built-in test modes—Pellets, Powder, Fine Powder, Foam, and Custom—allowing for quick selection based on sample type.

Outstanding service

I have been using Meritics for a number of years and they always provide outstanding service and support.
They have a rapid response turnarounds and are very knowledgeable of the techniques and products they provide.

Good service, very helpful

We use Meritics for the PM service and installation of all our FlowCams . Megan has been coming to our site for a number of years. She is very efficient in her work, but most of all Megan is very helpful. We have had issues with one of instruments after the install and Megan did her utmost to try and solve it while on site, even though it wasn’t solved Megan has been in contact with the supplier of the instrument to try and solve this problem for us.

Good Service

David, our service engineer as usual was good at communicating and setting up the recent service appointment, he arrived on time, did the service promptly and informed me of any problems. Friendly and helpful

TomA-446

Superb and prompt service

I have used this company through the laboratory I work for frequently. We specialise in soil analysis, and Meritics were chosen as they have extensive knowledge of the instruments we use. We have several laser particle diffraction analysers with a service contract, and service is always very prompt and meticulous….

JamesG-2483

Good experience over two years

Meritics have covered the annual servicing of our Multisizer 4e instrument since we purchased it from them just over two years ago. The application scientist who performed the servicing was friendly, knowledgeable, and extremely helpful, happily answering a barrage of questions about how best to use and maintain the instrument. All my interactions with Meritics staff have been positive. I would happily recommend them.

RajG-62

Fully committed to customer service

Service second to none, both units serviced and all questions answers by engineer while on site.

Highly recommend Meritics for equipment purchases and aftercare services

After owning one of our instruments for over 8 Years which was purchased from Meritics, it suffered its first breakdown. Upon contacting Meritics, I was instantly put through to an engineer who was very helpful. Upon inspection of the manual, it was decided that it would be more cost effective to have a Meritics engineer visit. The Meritics staff were very communicative and kept me up to date.

Excellent Service

Lovely, friendly and extremely helpful. David and his team are always on call with advise and are very easy to work with and are always happy to help.

Professional, Customer-oriented, fast service

We had issues with one of the aperture tubes provided by Meritics on a Friday afternoon, while very pressed for a review deadline. Meritics handled our inquiries very fast and professionally and helped us out by shipping us their spare tube to use in the mean time free of charge, while we waited for our new tube to arrive. Communication was very pleasant.

VeerleB

Very helpful and prompt

I emailed for some technical help and also to get some spares and both the engineer (David) and purchasing (Sophie) were very prompt to respond and helpful. We do have a service contract but I appreciated being able to email the engineer directly.
