Digital Penetrometer
Product Code : EL-BTLE-10423
Digital Penetrometer (code EL-BTLE-10423) is a compact, microprocessor controlled instrument for measuring the penetration of bituminous materials. A stepper motor drives the needle vertically while a contactless displacement transducer measures it over a 0-50 mm range at 0.01 mm resolution, and a 6 inch lateral touch screen plots the penetration/time curve and averages up to 6 tests. Needle, holder, weights, 6 containers and a levelled base plate are supplied.

What Is the Digital Penetrometer Used For?
The penetration test grades bitumen by consistency: a standard needle under a set load sinks into a sample held at a controlled temperature for a set time, and the depth it reaches, in tenths of a millimetre, is the penetration value, with harder binders giving lower values. Here the sample container stands in thermostatically controlled water, the instrument brings the needle to the start point by itself, releases it for the programmed time and measures the depth without contact, then plots the curve. Several results can be averaged on screen and saved to the USB flash drive or sent to a PC over LAN.
What to Specify When Ordering
- Quantity — the number of penetrometers required.
- Water bath — whether the water bath with thermo regulator and immersed probe is wanted for keeping the sample at the test temperature.
- Language — English or Italian for the instrument.
Frequently Asked Questions
What range and resolution does the Digital Penetrometer measure to?
Penetration is measured from 0 to 50 mm with a resolution of 0.01 mm, using a contactless displacement transducer while a stepper motor moves the needle.
Which timings can be programmed?
The delay time can be set from 0 to 999 sec and the penetration time from 0 to 9999 sec, and 8 reference positions can be programmed for the holder assembly.
What is supplied for running penetration tests?
The outfit includes the needle, needle holder, a 50 g weight and a 150 g additional weight, 6 containers, a centering guide and an anodised aluminium base plate with spirit level and adjustable levelling feet.
How is the sample kept at test temperature?
The penetration cup is placed in thermostatically controlled water, using a water bath with thermo regulator and immersed probe, which is offered as an accessory to the instrument.
How are results saved or transferred?
A USB flash drive is included for saving data and test reports, the USB port holds the test database, and the LAN port links the instrument to a PC.
How large and heavy is the unit?
Overall it measures 360 × 410 × 680 mm (width × depth × height) and weighs about 21 kg, with the 6 inch touch screen mounted at the side.
