A & P Instruments is a German company that specializes in the development and distribution of moisture analyzers. Founded in 2001, the company evolved from the long-standing family business ULTRA X Laborgeräte, continuing its product line. Its roots go back to 1925, when August Gronert established the original company and developed the first moisture analyzer in 1950. This innovation laid the foundation for all modern devices using the principle of simultaneous drying and weighing. In January 2025, a&p instruments was acquired by PCE Instruments. The company offers a wide range of moisture analyzers for various applications, including high-temperature analysis up to 600 °C, gypsum testing, and determining metal content in chips. Their products are known for precision weighing technology, ease of use, robust construction, and good value for money.
