Concrete Penetration Test Apparatus Function: Used for determining the setting time of concrete by means of penetrations resistance measurements on mortar. The concrete penetration drag force testing equipment is designed according to the standard of JTG E30-2005, this equipment looks handy and comfortable. It uses lever theory to read surveying pin force by meter, which gives a very convenient and correct testing. This equipment usually applies in such condensing time tests like varied cement, extra dose and varied proportion concrete mix, concrete mix of different temperature and environment. Techcnial parameters: (1) Dial max weight: 0-1000N (2) Division value: 5N (3) Dial precision: ±5N (4) Surveying pin circular area: 100mm² Surveying pin circular area: 50mm² Surveying pin circular area: 20mm²
