The TV12LT is a precision low-temperature visibility bath designed for viscosity testing at sub-ambient temperatures. With a temperature range of –42°C to +80°C and ultra-high stability (±0.01°C), it is ideal for determining kinematic viscosity according to ASTM D445, IP71, and ISO 3104 standards. The integrated cooling system and LED illumination ensure optimal visibility, while the heated window prevents condensation for uninterrupted viewing.

The bath accommodates four viscosity positions in a compact design with stainless-steel wetted parts, a drain, and an overflow outlet. Conforming to CE regulations, it includes safety features such as over-temperature protection and automatic fluid-level shutdown. The TV12LT is especially suited for testing aviation fuels, including those conforming to ASTM D7566, at –20°C and –40°C.
