The Wagner Turbidimeter determines the fineness of portland cement by measuring the specific surface area. A constant light source passes through a suspension of the cement and is detected by a photoelectric cell. Values are correlated to particle diameters measured of 50, 45, 40, 35, 30, 25, 20, 15, 10 and 7.5 micrometers. Turbidity changes as the particles settle from suspension. Turbidity is related to specific surface area, computed as described in ASTM and AASHTO procedures.
The Turbidimeter is supplied with photoelectric cell, light source, heat absorbing device, light filter, shield, and sedimentation tank in metal cabinet with wall mounts and adjustable shelf. Timing burette with stand, microammeter, stirring apparatus, wet sieving assembly with No. 325 sieve, flasks, test tubes, and instruction book are also included. A 6V storage battery or other constant emf source is required, but not included. For calibration, order NIST Portland Cement standard reference material separately.
Electrical: 115V/60Hz
Meets Test Methods:

The Gilson MA-15 Wagner Turbidimeter is a reliable and efficient instrument designed to accurately determine the fineness of Portland cement. With its advanced technology and precise measurements, it ensures that the specific surface area of the cement is measured with utmost accuracy.
Featuring a constant light source, the Wagner Turbidimeter allows the light to pass through a suspension of the cement, which is then detected by a highly sensitive photoelectric cell. This innovative technology enables the instrument to provide accurate values of particle diameters measured at various micrometer levels, ranging from 50 to 7.5 micrometers.
Turbidity, which changes as the particles in the cement settle from suspension, is directly related to the specific surface area. The computed specific surface area is determined using well-established procedures specified in ASTM and AASHTO guidelines, ensuring reliable and consistent results each time.
The Wagner Turbidimeter comes equipped with essential accessories to facilitate accurate testing. These include a photoelectric cell, light source, heat absorbing device, light filter, shield, and sedimentation tank, all housed in a sturdy metal cabinet with convenient wall mounts and an adjustable shelf.
To ensure seamless and precise testing, the Turbidimeter also includes a timing burette with a stand, microammeter, stirring apparatus, wet sieving assembly with a No. 325 sieve, flasks, test tubes, and an instruction book. However, it is important to note that a 6V storage battery or a constant electromotive force (emf) source is required for its operation and is not included.
The Gilson MA-15 Wagner Turbidimeter meets the rigorous requirements of renowned testing methods, including AASHTO T98 and ASTM C 115. It adheres to the highest standards, ensuring accurate and reliable results for every testing procedure.
For calibration purposes, it is recommended to separately order the NIST Portland Cement standard reference material, enabling users to calibrate the Turbidimeter for precise and consistent measurements.
With its exceptional features, reliable performance, and comprehensive accessories, the Gilson MA-15 Wagner Turbidimeter is the ultimate choice for laboratories and industries involved in cement testing, ensuring accurate and reliable results every time.
