Digital penetrometer

The apparatus consists of a penetrometer with adjustable head combined with a gear that permits a fine adjustment of the cone position right upon the bitumen sample: the results are showed on a digital display placed, together with an electronic timer in an independent control box.Optionally, refrigerated baths of various sizes are available (please require related technical bulletin): by connecting the bath to the transfer dish it is possible to penetrate samples while immersed in water at 25°C or other test temperatures.

• Robust flat aluminium base with centering device, spirit level and levelling screws.
• Encoder with 50 mm motion for penetration measurement.
• Digital penetration display with 1/10 mm accuracy.
• Electronic programmable timer for penetration time setting.
• Stainless steel cone plunger (47.5 g total weight) complete with electromechanical locking system. By pushing the start button the locking system is disabled: after the preset time (usually 5 seconds) the plunger is automatically locked in the reached position and the distance (penetration) from the top surface of the sample is shown on the display.
• Standard ASTM/IP needle, 2.5 g total weight.
• One 50 g  and one 100 g load weights.
• Button for manual handling of the plunger.
• Mirror and spot light.
• Easy access control box which contains all the electronics: anodized aluminium control panel with English written indications.
• English written user manual.
• For 220 V/50 Hz connections. Power consumption 50 W.
• Dimensions (l x w x h): mm 350 x 325 x 350 approx. Weight: kg 15 approx.
