ASTM S15F Non-Mercury Thermometer, 30 to 180F, NIST

ASTM S15F Non-Mercury Thermometer, 30 to 180°F, NIST Calibration: The Premier Choice for Precision and Safety

Experience the next generation of temperature measurement with the ASTM S15F Non-Mercury Thermometer. Engineered for unparalleled precision and user safety, this advanced liquid-in-glass thermometer offers a reliable range from 30°F to 180°F (equivalent to -1°C to 82°C). Designed as a direct, safer alternative to traditional mercury thermometers, it completely eliminates the risks associated with toxic mercury spills, making it an indispensable tool for environmentally conscious professionals and safety-focused organizations.

At its core, this thermometer utilizes a cutting-edge, non-toxic, and biodegradable blue indicating liquid. This innovative fluid not only delivers the same high-performance characteristics and responsiveness as mercury but does so without any associated health or environmental hazards. The vivid dark blue liquid is thoughtfully contrasted against a white-backed stem, ensuring exceptionally clear and precise readings, even in low-light conditions or when rapid observation is critical.

Key Features & Advantages:

• Uncompromising Compliance: This thermometer rigorously meets ASTM E1, E77, and E2251 requirements. This adherence guarantees superior reliability, consistent performance, and industry-standard accuracy, making it suitable for critical applications where regulatory compliance is paramount.
• Environmentally Responsible Indicating Fluid: The non-hazardous, biodegradable, and non-toxic blue liquid is a testament to modern environmental stewardship. It provides a responsible and safe option for laboratories, industrial settings, and educational institutions, removing the need for costly and complex mercury spill cleanup protocols.
• Optimal Visibility for Accurate Readings: The striking contrast of the dark blue fluid against the white-backed stem ensures that temperature indications are easily discernible, minimizing reading errors and maximizing efficiency, particularly during high-volume testing.
• Versatile Application: Specifically designed and rigorously tested, this thermometer is fully acceptable for Saybolt Viscosity Testing, a critical process in industries such as petroleum and lubricants. Its versatility extends to various other precision temperature measurement needs across multiple sectors.
• NIST Traceable Calibration Certification: Every ASTM S15F thermometer is shipped with a NIST Traceable Certificate of Calibration. This certification provides complete assurance that the instrument has undergone rigorous calibration in a controlled, ISO/IEC 17025 accredited laboratory, adhering to the highest international standards for measurement traceability. This means you can trust the accuracy of every reading for regulatory audits and quality control.

Detailed Specifications:

• ASTM Number: S15F
• Temperature Range: 30 to 180°F (-1 to 82°C)
• Immersion: Total Immersion. This design ensures the entire liquid column is exposed to the temperature being measured, providing the most accurate and representative reading for your sample or process.
• Application Suitability: Ideal for applications requiring precise temperature monitoring at low softening points, commonly found in materials science, asphalt testing, and chemical processing.
• Division (Resolution): 0.2 degrees (Fahrenheit), offering an exceptionally fine temperature resolution for highly sensitive measurements.
• Type: Non-Mercury, representing a safe and modern alternative.
• Length: 15.7 inches (400mm), a practical length for deep immersion into various vessels and systems while maintaining easy handling.

Meticulous Calibration Process:

The ASTM S15F Non-Mercury Thermometer undergoes a meticulous calibration process to guarantee its exceptional accuracy. Each instrument is calibrated using a high-stability liquid bath, ensuring uniform temperature distribution during the calibration procedure. This is followed by a direct comparison to certified Precision Reference Thermometers (PRT) and Standard Platinum Resistance Thermometers (SPRT), which are themselves traceable to national standards. Before any testing begins, each thermometer is thoroughly inspected for any manufacturing defects, such as hairline cracks or liquid-column separation, confirming it meets the most stringent standards of quality and reliability. Measurements are precisely conducted at five distinct temperature points across its range, generating comprehensive and dependable calibration data that is included with your certificate.

This thermometer stands as an excellent choice for professionals across the USA who demand a reliable, accurate, and crucially, a safe alternative to traditional mercury-based instruments. Its robust construction, coupled with strict adherence to ASTM standards and American expertise, renders it suitable for a diverse array of applications, from cutting-edge research laboratories to demanding industrial process control environments.

Optimal Storage and Protection for Longevity:

To ensure the prolonged accuracy and operational life of your Non-Mercury Thermometer, proper storage and protection are vital:

• Preventing Fluid Column Separation: To safeguard against potential fluid column separation—a common issue with liquid-in-glass thermometers if stored improperly—it is highly recommended to store the Non-Mercury Thermometer vertically. Utilizing a specialized storage rack designed for laboratory thermometers is the best practice for maintaining its integrity.
• Enhanced Protection with a Thermometer Well: For applications in harsh environments or where physical impact is a concern, a thermometer well provides an essential layer of additional protection. This accessory also aids in thermal stabilization, protecting the delicate glass bulb from rapid temperature fluctuations or physical damage. It is particularly crucial for safeguarding glass laboratory thermometers when used in ovens, aggressive chemical baths, or other exposed industrial settings.
