The apparatus consists of a constant temperature bath capable to work in the range from -10 to 40 °C (thanks to a built-in cooling compressor) with an electrically powered tractor that pulls apart at a determined speed the two ends of two briquet specimens: the elongation is measured by means of a pointer on the tractor and a graduated scale fixed to the cover.

• Stainless steel bath thermally insulated: complete with drain valve.
• Chromium plated brass pump: it provides an adequate stirring of the liquid in the bath.
• Stainless steel heater.
• Microprocessor thermoregulator with PID action: built-in digital display 0.1°C accuracy. Probe: Pt100 RTD. Working range: from -10 to 40°C.
• Safety device against overheating and low level with alarm lamp.
• Built-in hermetic cooling compressor: CFC/HCFC-free gas.
• Acrylic hinged cover: it helps to maintain a constant temperature in the bath providing a clear view of the inside.
• Traction carriage with two-speed motor for 10 and 50 mm/min: the carriage supports 2 briquet molds. Automatic stop safety switch that stops the carriage when the maximum elongation has been reached. Traction length: 50, 100  or 150 cm.
• White screen fixed to the bottom of the bath: it permits a more clear vision of the elongated specimen during the test.
• For 220 V/50 Hz connections: 1800 W power consumption.
• Dimensions (l x w x h): mm 1800 x 450 x 1300 approx (AD0113-200) mm 2400 x 450 x 1300 approx (AD0113-250). Weight: 250 kg approx.
