True Density Meter Laboratory True Density Test Equipment for Solids Digital Solid Density Measuring Instrument
Product details
1.Full constant temperature test system
Constant temperature is a necessary condition to obtain accurate and reliable data. Due to the nature of gas expansion and contraction, the change of temperature will directly affect the accuracy of gas quantification technology. Our company has developed and obtained full constant temperature technology, using advanced wind and heat circulation device, built-in multi-point intelligent temperature control terminal, to achieve full constant temperature of the entire test system, constant temperature control accuracy can reach 0.01ºC. The application of the system can effectively improve the accuracy and repeatability of the data, avoid the direct blowing of the air conditioner, the ventilation of the window, and the influence of the ambient temperature difference on the measurement accuracy and repeatability of the instrument.
2.Accurate volumetric measurement system
The volume of a general solid material can be calculated by measuring its length, width and height. However, most solid surfaces are irregular and have holes or cracks of varying sizes. The solid itself has open holes, through holes and closed holes, and its volume (that is, skeleton volume) cannot be accurately obtained by traditional methods. The essence of gas densitometry instrument is to measure volume, the test system in addition to the constant temperature system, but also need to have an accurate quantitative system. Piaud Instruments use accurately calibrated double quantifiers, multi-structure sealed tanks, and superior vacuum technology to protect the testing of solid materials.
3.Simple and clear operation interface
LS-1100 true density analyzer gets rid of computer control, and the host is embedded with a more stable WINDOWS CE industrial control system, providing users with a simple and clear operation interface. One-click startup, automatic testing and data storage, built-in storage space for at least 2 million test reports. View and retrieve past data at any time, reserve USB interface, export and print immediately.
4.Scientifically rigorous equipment calibration
The calibration of LS-1100 true density meter is carried out in three ways: 1. Measuring the empty bin volume and repeating the test for more than 10 times to ensure the volume repeatability deviation < 10 microliters; 2, the test has been strictly measured stainless steel standard body, repeated testing more than 10 times, to ensure that the equipment test volume value and standard value deviation < 10 microliters; 3, provide coal standard samples to ensure that the density value is within the specified range. (There are commercially available methods of using density values or simply using the volume value of the metal for calibration, which are not reasonable. The true density instrument is actually a volume measuring instrument, and it is unreasonable to calibrate the instrument with density value. The uncertainty range of the volume value of the metal is large, which can not meet the use requirements of the gas true density meter.
