ASTM S12F Non-Mercury Thermometer, -5 to 215F

ASTM S12F Non-Mercury Thermometer, -5 to 215F

The ASTM S12F Non-Mercury Thermometer offers a precise temperature measurement range from -5 to 215°F, with clear 0.5°F graduations. Designed for total immersion, this thermometer is specifically mandated for use in gravity testing but is versatile enough for various other applications within its temperature range. Its total length is 16.7 inches (425mm), providing ample scale for accurate readings.

As a safe and environmentally friendly alternative to traditional mercury thermometers, these ASTM-compliant thermometers feature a proprietary blue indicating fluid. This liquid is biodegradable, non-toxic, and non-hazardous, ensuring safety in any lab environment. The dark blue color of the fluid stands out against the white-backed stem, making it easy to read and reducing the risk of measurement errors. These thermometers deliver the same high performance and accuracy as their mercury counterparts, meeting the stringent requirements of ASTM E1, E77, and E2251.

Features:

• ASTM Certified: Fully complies with ASTM E1, E77, and E2251 standards for accuracy and reliability.
• Safe Indicating Fluid: Uses a non-hazardous, biodegradable, and non-toxic blue liquid as a safe alternative to mercury.
• High Visibility: The dark blue fluid provides excellent contrast against the white-backed stem for quick and easy readings.
• Versatile Application: While specified for gravity testing, it is also acceptable for use in Saybolt Viscosity Testing and other relevant procedures.

Specifications:

• ASTM Number: S12F
• Temperature Range: -5 to 215°F
• Immersion: Total
• Primary Application: Gravity
• Division: 0.5°F
• Type: Non-Mercury, Liquid-in-Glass
• Length: 16.7in (425mm)

Proper Care and Accessories:

To ensure longevity and maintain accuracy, it is crucial to store Non-Mercury Thermometers vertically in a dedicated storage rack. This prevents the fluid column from separating. For added protection and to ensure thermal stabilization, especially when used in ovens or other exposed environments, consider using a Thermometer Well.
