The TBTZRD-5 penetrometer is a high-precision instrument designed to determine the consistency and hardness of materials. It measures the displacement of a standard needle under specified loads and temperatures.

Standards: ASTM D5

• Equipped with a circulating constant temperature water bath to maintain integrity during testing.
• A digital timing controller ensures the needle is released and locked at precise intervals for maximum consistency.
• Utilizes a digital sensor for ultra-fine measurement accuracy and data reliability.
• Features an LED cold light source that illuminate without emitting heat, preventing any temperature-induced measurement errors.

TBT-2801E1 penetrometer is designed for the penetration test on numerous asphalt materials, such as highway bitumen, modified asphalt, liquid petroleum asphalt or residue of emulsified asphalt after evaporation material. This penetrometer also can be used to test a wide variety of food materials such as cheese, cream, butter, and yogurt.
