ASTM S15C Non-Mercury Thermometer: Precision Measurement for Demanding Applications

Introducing the ASTM S15C Non-Mercury Thermometer, engineered for precise temperature measurement across a broad range of -2 to 80°C. This advanced liquid-in-glass thermometer offers the same exceptional performance and accuracy as traditional ASTM mercury thermometers, but with the added benefit of using a safe, blue indicating fluid. Developed with environmental responsibility in mind, our proprietary fluid formula is biodegradable, non-toxic, and non-hazardous, ensuring peace of mind for both users and the environment. The distinct dark blue color of the fluid provides excellent contrast against the thermometer's white-backed stem, allowing for clear and easy readings even under various lighting conditions.

This robust thermometer is meticulously crafted to meet stringent industry standards, making it ideal for critical laboratory and industrial applications where accuracy and safety are paramount.

Key Features:

• ASTM Compliance: Fully compliant with ASTM E1, E77, and E2251 requirements, ensuring reliability and adherence to established measurement protocols. Specifically designed for applications like Low Softening Point testing.
• Environmentally Friendly: Utilizes a non-hazardous, biodegradable indicating fluid, offering a safer alternative to mercury without sacrificing performance. This reduces environmental risk and simplifies disposal procedures.
• Superior Visibility: The vibrant dark blue fluid stands out sharply against the white-backed stem, minimizing reading errors and improving operational efficiency.
• Application-Specific: Approved and highly recommended for use in demanding Saybolt Viscosity Testing, where precise temperature control is crucial for accurate viscosity measurements.
• Precision and Resolution: Features a fine division of 0.2 degrees, enabling highly accurate readings for critical processes.
• Total Immersion Design: Engineered for total immersion, meaning the entire liquid column and the part of the stem containing the fluid must be at the temperature being measured for optimal accuracy.

NIST Traceable Certificate of Calibration Included:

Each ASTM S15C thermometer comes complete with a NIST Traceable Certificate of Calibration. This certificate confirms that the thermometer has undergone a rigorous, five-point calibration process in an ISO/IEC 17025 accredited laboratory. This accreditation serves as your guarantee that all calibration procedures are performed in a qualified, controlled environment, meeting international standards for technical competence.

Our calibration process involves direct comparison against a Precision Reference Thermometer (PRT) and a Standard Platinum Resistance Thermometer (SPRT) within a high-stability liquid bath. Before calibration, each thermometer undergoes a thorough visual inspection to check for any cracks, liquid-column separations, or other manufacturing defects that could compromise accuracy. Measurements are meticulously recorded at five distinct temperature points across the thermometer's range to ensure consistent performance. This comprehensive approach provides unwavering confidence in the accuracy and reliability of your readings.

Storage and Protection Recommendations:

To maintain the integrity of the fluid column and prevent separation, always store Non-Mercury Thermometers vertically. We recommend using a dedicated thermometer storage rack to ensure proper upright positioning and protection.

For applications in ovens or other exposed environments, consider utilizing a Thermometer Well. These wells provide crucial protection for glass laboratory thermometers against physical damage and help to maintain thermal stabilization, ensuring more consistent and accurate readings by minimizing external temperature fluctuations.
