The ASTM Equivalent S78F Non-Mercury Thermometer is a reliable and safe option for measuring temperatures ranging from 295 to 315 degrees Fahrenheit. While these thermometers have not been officially reviewed and accepted by ASTM, they possess the same physical and performance characteristics as ASTM thermometers for their referenced applications.
One of the key features of these thermometers is the use of a safe blue indicating liquid. This liquid is not only biodegradable but also non-toxic and nonhazardous, ensuring the safety of both the user and the environment. Additionally, the dark blue color of the indicating liquid makes it easily readable against the white-backed stem, allowing for quick and accurate temperature readings.
With an ASTM Number of S78F, these thermometers are suitable for immersion in a variety of applications, particularly Saybolt Viscosity testing. The thermometer has a division of 0.5 degrees, allowing for precise temperature measurements.
Measuring at a length of 11.4 inches (290mm), this non-mercury thermometer is designed for easy handling and usability. It is important to store these thermometers vertically using a storage rack to prevent fluid column separation and ensure their longevity.
For added protection and thermal stabilization in ovens or other exposed environments, the Thermometer Well can be used in conjunction with these thermometers. The well provides a secure housing for the glass laboratory thermometer, maintaining its accuracy and extending its lifespan.
It's worth noting that this thermometer meets the test methods outlined by ASTM, including ASTM E2251, ASTM E77, and ASTM E1. These standards ensure that the thermometer meets the necessary requirements and performs reliably in various laboratory and industrial settings.
