ASTM S15F Non-Mercury Thermometer, 30 to 180F

ASTM S15F Non-Mercury Thermometer: Safe, Accurate, and Environmentally Responsible Temperature Measurement

Introducing the ASTM S15F Non-Mercury Thermometer, engineered to deliver the precise and reliable temperature readings you expect, while prioritizing safety and environmental responsibility. This advanced liquid-in-glass thermometer offers a comprehensive measurement range from 30 to 180°F (approximately -1 to 82°C), making it ideal for a variety of critical laboratory and industrial applications, especially those requiring low softening point determinations.

Uncompromised Performance, Enhanced Safety Designed as a direct, safer alternative to traditional mercury thermometers, the ASTM S15F utilizes a proprietary, biodegradable, non-toxic, and non-hazardous blue liquid as its indicating fluid. This innovative formula ensures that you maintain the same high-performance characteristics and accuracy found in ASTM Mercury Thermometers, without the risks associated with mercury exposure or disposal. The distinct dark blue color of the fluid provides excellent contrast against the white-backed stem, guaranteeing easy and precise readability even under challenging conditions.

Key Features and Benefits:

• ASTM Compliance: Meets stringent ASTM E1, E77, and E2251 requirements, ensuring accuracy, consistency, and suitability for standardized testing procedures. This guarantees that your measurements adhere to industry benchmarks.
• Eco-Friendly Indicating Fluid: The non-hazardous, biodegradable fluid offers a responsible choice for your lab, eliminating concerns about mercury contamination and simplifying waste management.
• Superior Readability: The vivid dark blue fluid against a stark white stem minimizes reading errors and reduces eye strain during prolonged use.
• Specialized Application: Specifically designed and acceptable for use in Saybolt Viscosity Testing, a crucial method for determining the viscosity of petroleum products.
• Total Immersion Design: Engineered for total immersion, ensuring that the entire column of liquid is at the temperature being measured for maximum accuracy.

Important Storage and Protection Recommendations:

To maintain the longevity and accuracy of your Non-Mercury Thermometer, it is crucial to always store it vertically in a suitable storage rack. This practice prevents the fluid column from separating, which can lead to inaccurate readings and premature wear.

For optimal performance and to safeguard your investment, consider using a Thermometer Well. This accessory provides robust physical protection for glass laboratory thermometers in harsh or exposed environments, such as ovens. Additionally, it helps achieve thermal stabilization, ensuring that the thermometer equilibrates with the surrounding temperature quickly and maintains accurate readings over time.
