The product name:Insulation tester
use：Insulation tester by measuring the spray before and after the change of the sample quality, not flooded parts of the sample to calculate the percentage by volume.
(1) hydrophobic tester, as shown in figure 1.
A. water spray device: the metal nozzle, glass rotor flowmeter and the voltage stability of water, with rubber pipe connection in the middle. Metal nozzle is located in the center of test of the longitudinal symmetry plane, and it can move in the sample rack. Glass rotor flowmeter of the flow range of 10-100 l/h, accuracy of 2.5 on the Richter scale are unlikely.
B. specimen holder: specimen holder to a 450 Angle placed on a can adjust the level of support.
C. metal nozzle: spray like convex circle. On its uniform 19 Φ 0.9 mm hole, when the nozzle is shown in figure 1 in regulations on the location of the test, the sample by leaching area is 148 mm, lateral size of the nozzle structure is shown in figure 2.
(2) balance: minimum degree value is not greater than the known quality of 0.5%.
(3) the drying oven.
(4) thickness gauge
