PHOTOMETRIC TEST APPARATUS FOR QUICK DETERMINATION OF SO3 IN CEMENT.

The Photometric Test Apparatus offers a highly efficient solution for determining the sulfur trioxide (SO₃) content in cement, crucial for ensuring cement quality and compliance. Featuring a double light intensity meter, the apparatus provides enhanced measurement accuracy, and the built-in constant voltage transformer maintains stable power, ensuring consistent readings. The high-quality components ensure durability and accuracy, making it suitable for both laboratory and industrial applications.

The test procedure is straightforward: a prepared solution of cement and hydrochloric acid (HCl) in a fixed ratio is poured into the photo glass tube. As the solution progresses, light transmission through the tube decreases until it disappears. At this point, a reading is taken, and using a calibration chart, the percentage of SO₃ can be directly determined. This quick, easy, and accurate method allows for multiple tests in a short time, supporting high throughput in cement quality control.

This model is built to export quality standards and is suitable for frequent and reliable SO₃ analysis. Additional calibrated photo tubes are available upon request for enhanced measurement precision.
