COLUMBUS, Ohio (July 15, 2014) – METTLER TOLEDO announces a new line of Thermomechanical Analyzers, providing nanometer-resolution length measurements over a wide temperature range. The new TMA/SDTA 1 features sample supports and probes that are easy to handle, and many intelligent features with the well-known One Click™ operation, ensuring work flows are ergonomic and efficient. TMA/SDTA 1 incorporates Swiss precision mechanics and is available in four versions with furnace systems optimized for measurements between –150°C and 1600 °C:
• Large furnace - room temperature to 1100 °C • High temperature - room temperature to 1600 °C • Intracooler model - measurements from – 80 °C to 600 °C • Liquid nitrogen model - measurements from –150 °C to 600 °C
Up to 16,000,000 data points are available for the entire measurement range of ±5 mm. Both small and large samples (up to 20 mm) can be measured with 0.5 nm resolution - without the need for range switching.
Touchscreen Terminal for the TMA/SDTA 1 – with One Click™ Technology
The touch-sensitive color terminal for TMA/SDTA 1 presents clear and precise information and is easily seen from a distance. The patented One Click function allows users to easily start predefined methods from the terminal at the touch of a button. All force and length calibration routines are controlled via the terminal; ensuring calibrations are performed reliably and easily. The touch screen can be used to control the determination of sample length and also to initiate the transfer of data to the software, eliminating possible transcription errors.
SDTA Signal
The TMA/SDTA 1 is the only TMA instrument on the market with the well-proven and superior SDTA technology with unsurpassed temperature accuracy. The SDTA measures the sample temperature in very close proximity to the sample, enabling temperature adjustment using the melting point of reference substances or through a change in length. It uses a model (US Patent 6146013) to calculate the difference between the measured sample temperature and the reference temperature, so in addition to length change, the SDTA signal is available as a measurement quantity. In many cases, this can facilitate the correct interpretation of a measurement curve.
Easy Sample Installation
The sampling area is freely accessible for installation of the sample holder and measuring probe, so operations can be performed quickly and easily. An indentation ensures that the sample holder can only be installed in the correct position. The measuring probe is securely attached to the length sensor (LVDT) by means of a magnet and can be easily exchanged. Different sample holders and measuring probes are available for each measuring mode, allowing users to choose the best configuration for each application.
