Ezilab's Low Temperature Kinematic Viscometer EZL-KV200 serves petroleum laboratories that need sub-zero kinematic viscosity testing well below the ambient-to-100°C range of the standard capillary units in this catalog. Reaching -65°C with dual compressors, this viscosity instrument measures cold-weather viscosity performance for fuels and lubricants where low-temperature flow characteristics matter as much as, or more than, standard-temperature viscosity — a genuinely different testing scope from the room-temperature-and-above kinematic viscometers elsewhere in this line. Dual compressors are what make that -65°C floor achievable and sustainable, providing the cooling capacity a single-compressor system couldn't maintain at that depth, particularly important for kinematic viscosity testing where temperature stability during the timed capillary flow measurement directly affects result accuracy. That -65°C capability aligns with the same cold-temperature testing scope as the pour and cloud point tester in this catalog, though this instrument measures kinematic viscosity specifically rather than pour or cloud point, giving petroleum labs a complementary low-temperature measurement covering a different specification parameter. Petroleum formulation labs and cold-climate fuel or lubricant testing programs needing viscosity data at genuinely low temperatures, rather than standard ambient-range testing, get purpose-built capability here. EziLab's Viscosity and Low Temperature Kinematic Viscometer cover cold-temperature petroleum viscosity testing needs across USA petroleum laboratory settings.
