ASTM S113F Non-Mercury Thermometer, 30 to 350F, NIST

ASTM S113F Non-Mercury Thermometer, 30 to 350°F, NIST-Traceable Calibration

The ASTM S113F Non-Mercury Thermometer is an ideal alternative to traditional mercury-based thermometers, offering identical physical and performance characteristics for referenced applications. While not yet reviewed and accepted by ASTM for specific applications, this thermometer is a reliable and eco-friendly option for your laboratory or industrial needs.

Key Features:

• Eco-Friendly Design: Uses a safe, blue biodegradable indicating liquid that is nontoxic and nonhazardous. The vivid dark blue color contrasts sharply against the white-backed stem, ensuring easy readability.
• Wide Temperature Range: Measures temperatures from 30 to 350°F with a division of 1.0°F, making it suitable for a variety of applications.
• Total Immersion: Designed for total immersion, ensuring precise and reliable measurements.
• Durable Construction: Built with a 16-inch (410mm) length for durability and enhanced usability in demanding environments.
• Application-Specific Use: Well-suited for bituminous softening point measurements, among other uses.

Calibration and Accuracy:

This thermometer comes with a NIST Traceable Certificate of Calibration, providing confidence in its accuracy and reliability. The calibration process is conducted in an ISO/IEC 17025 accredited laboratory, ensuring the highest standards of precision. Key points about the calibration process include:

• Measurements taken at five specific temperature points for accuracy.
• Calibration performed using a high-stability liquid bath in direct comparison with a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT).
• Inspected for cracks and liquid-column separations before testing to ensure functionality and performance.

Storage and Maintenance:

To prevent fluid column separation, always store the thermometer vertically in a storage rack. Proper storage maintains the integrity of the liquid column and ensures long-term accuracy.

Additional Accessories:

For protection and thermal stabilization, use the thermometer with a Thermometer Well. This accessory is essential for safeguarding the glass thermometer in ovens or other exposed environments, ensuring precise and stable temperature readings.

Upgrade your laboratory or industrial setup with the ASTM S113F Non-Mercury Thermometer, a safe, accurate, and eco-friendly alternative designed for professional results.
