ASTM 120C Thermometer

ASTM 120C Thermometer – Precision Temperature Measurement for Viscosity and Process Control

The ASTM 120C thermometer is a specialized model in the ASTM standard thermometer series, designed for precise measurements in laboratory and industrial environments. It is particularly used in kinematic viscosity tests at 40°C (commonly with Fenske viscometers), quality control, and sensitive temperature processes for various industrial oils, light hydrocarbons, and clear fluids. Its high accuracy makes it a reliable instrument for laboratories.

Overview
Manufactured by Ludwig Schneider, Germany, the ASTM 120C thermometer has a length of 30 cm and covers a narrow range from 38.6°C to 41.4°C. It provides precise readings with a resolution of 0.05°C. The thermometer features durable engraved scales and a unique serial number for calibration purposes, making it suitable for harsh chemical and thermal conditions.
