Watts Press ur Meter
0.00৳
The original Watts Press-Ur-Meter, w/Wood Case is used to test the percentage of air in a freshly mixed concrete sample. The test method is based on Boyle’s Law and releases a known volume of air at a known pressure into the concrete sample which contains an unknown volume of air. The resultant change in the sample’s volume correlates directly to the percentage of entrained air in the sample and can be read directly from the gauge. The pressure meter is made from the highest quality components for years of trouble-free service.
Dimensions and accuracy of this meter exceeds requirements of ASTM. Included are: Calibration Vessel, Calibration Tubes, 24in (610mm) Tamping Rod, Aluminum Straightedge, Syringe for water, Carrying Case and operating instructions. Cast aluminum chamber is 1/4ft3 and may also be used for unit weight and yield determinations
