Used ROHDE & SCHWARZ DMV 400 #129374 for sale

ROHDE & SCHWARZ DMV 400 is a top-of-the-line Volumetric Nebulizer that serves as an electronic test equipment for aerosol concentration measurements. This device is a digital nebulizer that offers excellent repeatability for titration accuracy and easier operation with fewer external connections. DMV 400 can be used for detection of aerosol particles in saline samples and air, making it invaluable for research in air pollution, lung physiology and physiology, pharmaceutics and automotive studies. ROHDE & SCHWARZ DMV 400 comes with an integrated syringe pump to precisely feed the aerosol sample into the sample chamber. The type of syringe is selectable, allowing a wide range of sample quantities to be used, ranging from 5 μl up to 500 μl. The device also offers dual susceptibility filter operation mode, meaning it can be used for measuring both nanoparticles and non-nanoparticles. In order to accurately capture as many particles as possible, the test chamber size is optimized for the maximum aerosol concentration, reaching a maximum of 300 mg/m³ in only 15 minutes. It also has a built-in automatic aerosol generation mode, which allows for continuous and reliable testing. The digital nebulizer achieves increased accuracy with the addition of a volumetric bath that is encased in a dual-walled stainless steel body. The presence of an infrared light source enable accurate and simultaneous measurement of both the aerosol concentration and the particle size. DMV 400 also has a built-in temperature control and stabilization system that enables temperature control during measurements. This offers better accuracy as the sample is less likely to be affected by ambient temperature. ROHDE & SCHWARZ DMV 400 provides a range of useful features such as a three-way valve system, allowing users to switch between the sample chamber, the measurement chamber and the analysis chamber with one simple movement. It also has a three-way pressure valve system to control the pressure of the particle laden air, allowing for better repeatability and longer service life. The device is user-friendly, allowing the user to access an interactive graphical user interface and access diagnosis features with a simple finger touch. In addition, DMV 400 has a library of over 100 test protocols, each customizable to the user's requirements for efficient testing. ROHDE & SCHWARZ DMV 400 is an essential device for any research facility undertaking aerosol concentration measurements. It provides accurate, repeatable and reliable measurements of aerosol particles and is user friendly with easy operation and effective diagnosis functions.
