Compact, powerful, benchtop Laser Flash Diffusivity system equipped with Class 1 Nd: Glass Laser Source provides a collimated, monochromatic 15Joules energy pulse and can measure diffusivity from ambient up to 1200°C.
Sales PromotionsThe Discovery Laser Flash DLF 1200 employs a custom Class 1 Nd:Glass Laser pulse source to provide a collimated, monochromatic energy pulse with a 300 μs to 400 μs pulse width. Ideal for labs that need to measure thermal diffusivity, heat capacity or thermal conductivity at temperatures up to 1200°C, or require the power of a laser in a compact benchtop instrument.
Equipped with a liquid nitrogen-cooled IR detector, DLF 1200 provides high precision, quick response, non-contact measurements in air, inert gas or vacuum to 10-3 torr. Simple to operate and safe to use, easy to maintain and very economical to operate, these systems are suitable for research and development programs, as well as quality control.
Unparalleled Accuracy
Unparalleled Accuracy
All Discovery Flash source modules employ full-time pulse mapping and recording capability. This allows for precise pulse-shape and pulse-width correction calculations and the most accurate determination of the t0.
The Discovery Flash data analysis software also employs the latest methods for heat loss corrections. The Clark and Taylor and Curve Fitting algorithms are utilized as the most accurate general purpose procedure to determine thermal diffusivity based on the finite pulse width, radiation heat losses, and non-isothermal local sample conditions. Additionally, more than 20 different analysis models and correction programs are incorporated into the software, providing the highest accuracy for all material types.
Sensor Technology
Sensor Technology
Discovery Flash instruments utilize high sensitivity, quick response sensors for the most accurate measurement of transient temperature changes. As an integral component of the environmental module, the detector is factory-aligned to the sample and does not require user exchange or alignment. The detector type is selected specifically for the operating temperature range of the Environmental Module. For moderate to high temperature measurements, an indium antimonide (InSb) IR detector is employed. The IR detector is cooled with liquid nitrogen to ensure the most stable output and maximum repeatability.
Standard and Universal
Standard and Universal
The flash method is widely accepted and is documented in ASTM E1461, ASTM E2585, DIN EN821, DIN 30905, ISO 22007-4:2008, and ISO 18755:2005. All TA Instruments Discovery Flash instruments conform to these standards and can be relied on to produce accurate, repeatable results that can be easily compared between laboratories.
