It is designed to determine hardness number and load quotient of the polyurethane foam. It consists of an arrangement wherein the load is indicated on a digital indicator connected to the electronic load cell & the deflection is also indicated on the digital indicator. An arrangement is provided for switching off the motor automatically when the desired compression of the foam is reached. The whole equipment is built on a rigid fabricated steel frame. The machine operates on 220/230Volts, 1 Ø A.C. supply.
| Indenter | Flat circular indenter having an area of 323cm² |
| Load measurements | On a digital indicator |
| Speed of movement approx. of indenter. | Between 2 to 3mm per second. |
For polyurethane foam consists of a loading frame having flat metallic platform for keeping the test specimen and a circular indentor of specified shape and size which is repeatedly lifted off and pressed against the foam flat with a motorized movement of the indentor.
| Dimension of test specimen | 380 x 380 x 50mm |
| Diameter of Indentor | 250mm |
| Number of Specimen | 1 |
| Movement of Indentor | Adjustable. |
| Pounding Frequency | 70 ± 2cpm |
| Motor | 1/2 HP single phase 230Volts A.C. |
| Pre-Set Counter | Digital |
It consists of an arrangement to hold a test specimen in a square opening in a cylindrical chamber so as to expose a known area to the flow of air through it.
| Test Area | 50mm x 50mm |
| Dimension of Test Specimen | 51mm x 51mm x 25mm |
| Rotameters/Water Column | 500 to 5000 lph and 1200 to 12000 lph. Accuracy ± 3% of FSR in each range. |
| Pressure Indicator | Digital pressure indicator with pressure transducer to measure pressure differences of upto 200mm water column. |
