709SD is a high-precision, high-density quartz crystal microbalance (QCM) used in sensor, analytical and experimental measurement applications. It is designed for accurate measurement of extremely small amounts of mass or surface area on a sample, by using a quartz crystal as a mass-sensing device. The 709SD is used in the fields of materials science, tribology, life sciences, nanotechnology, surface physics and chemistry and more. It is capable of detecting, in some cases, changes of only a few nanometers in surface area or mass on a sample.

In operation, a vibration sensor is typically coupled to a thin film quartz crystal with a frequency of between 30 and 120 MHz. By applying an oscillating RF driver to the crystal, tiny changes in applied mass can cause a change in frequency of the oscillator. This frequency change is then read by the sensor and converted into measurements of mass or surface area in, for example, micro-grams, nanograms or nanometers. The 709SD can measure very low mass changes, which makes it suitable for use in advanced research and development areas.

The 709SD is designed for use with a wide variety of substrates or samples, such as silicon wafers, single-end and double-sided films, magnetic substrates, thin films and more. It is also capable of measuring surface area changes between 10 and 1000 nanometers. Additionally, it can be used with a wide range of sample shapes as well as samples with different shapes.

The 709SD offers a number of unique features that make it ideal for use in a wide range of applications. For example, the 709SD has an integrated frequency counter that allows it to measure large frequency changes accurately with a resolution of up to 0.1 Hz. Additionally, the 709SD features a wide operation range and can measure mass or surface area changes at temperatures from -40° to 110°C. Furthermore, it can measure very small masses of as little as 1 nanogram.

The 709SD is a highly versatile, accurate and reliable device. It is ideal for research, development and testing in a wide range of fields. With its ability to measure very small changes in mass or surface area, it can provide researchers and developers with valuable data for their experiments and projects.
