Herzog engineers continue to develop the latest technology for testing cold behavior, distillation, flash point, vapor pressure, viscosity and other physical properties.

Herzog by PAC, originally established in 1931 is a long-established, comprehensive line of laboratory instruments for testing atmospheric and vacuum distillation, flash point, vapor pressure, bitumen properties, cold flow properties, viscosity and other physical properties of materials. Distillation and flash point analysis is provided by systems including the OptiDist and the HDV 632; viscosity and Bitumen testing by systems such as the HVM 472 and the HRB 754 Ring & Ball; and fuel classification by systems such as the CID 510 Derived Cetane Number.

As a highly experienced provider of physical testing instruments, we are an active member in standards organizations and lead standard development to guarantee that the methods meet customer requirements of precision and ease of use.

Products

Herzog early on pioneered efforts to automate traditional manual methods of testing in order to save manpower and eliminate user errors. Herzog also took the lead in efforts to develop and standardize new, alternative lab methods where the hallmarks were low sample volume requirements, achieving faster results, higher precision in analysis, and greater ease of use by operators with lower general skill levels.

Herzog provides complete solutions, including highly experienced customer service and certified reference materials for instrument calibration and validation.
