PSI was founded in 1963 (60 years ago) with the aim of designing and manufacturing freezing point osmometers and freezing point meters with high precision, accuracy, and reliability. Our osmometers and freezing point meters can be used in clinical laboratories, research, small animal testing, drug quality control, intravenous injection solutions, beverages, reagents, eye solutions, incoming inspection, dairy products, petroleum, and many other fields. PSI has pioneered freezing point penetration measurement technology in many aspects, including the development of a simple, non interactive calibration program for all of our instruments. Due to the characteristics of the freezing point principle, it is highly suitable for applications such as general chemical analysis, drug abuse, quality control, drug development, reagent development, and industrial testing. We are at the forefront of the market in providing smaller 10 µ L sample osmometers. We also offer a relatively complete series of osmotic pressure gauges to meet the needs of each user. We have received a call from a customer requesting to repair an instrument they have been using in the laboratory for 25 years or more. This also confirms that the advantage of our instrument in terms of quality is obvious.
