Complies to following International Standard:

ASTM D5

Test Objective:

The test objective is to evaluate the hardness/firmness of Soap using a Needle according to ASTM methods. A standard needle is released from a Penetrometer and allowed to drop freely into the sample for 5 seconds (or a different specified interval) at constant temperature.

Silent Features:

• Compact design and rugged construction ensures long service life and facilitates transport for field applications.
• Sturdy cast iron base provides excellent support.
• Built‑in spirit level and leveling screws ensure proper alignment during testing.
• Supplied with Needle (2.5 gm), weight (50 gm) and Digital time controller 

Brief construction details:

• The apparatus consists of a cast aluminum base with an iron stand on which moves an aluminum arm.
• A 6" dial is fixed on this arm and a brass chromium plated rod slide through the lower portion of the arm.
• A Needle with plunger is fitted to this rod.
• The dial is graduated from 0‑400 in one tenth millimeter sub division.
• Weight of the Needle and plunger match the criteria of ASTM requirements.
• The base of the instrument is also user ‑ adjustable.
• It can be lifted up or down with the jack provided at the bottom.
• The penetration time is controlled and indicated on Digital Timer Panel with least count of 0.1 second.
• The automatic digital timer and electrical arrangement, which on push of a button, automatically releases the plunger with Needle by a magnetic device.
• The penetration value is measured and indicated on dial gauge.
• Dial Gauge measures the penetration distance in 1/10th mm accuracy. 

Supplied complete with following Accessories:

1.   Digital time controller with auto magnetic clutch release mechanism on push of a button. 1 No.

2.   Having timing range 0.1‑9999.9 seconds (No need of stop watch).   

3.   Weight of 50 grams - 1 No.
