ASTM S59F Non-Mercury Thermometer, 0 to 180F, NIST

ASTM S59F Non-Mercury Thermometer, 0 to 180F, NIST

The ASTM S59F Non-Mercury Thermometer provides precise temperature readings from 0°F to 180°F, with clear 1.0°F graduations. Designed for total immersion applications, this thermometer is specified for tank testing but is versatile enough for various lab environments within its temperature range. Its total length is 12.0 inches (305mm), ensuring it can reach required depths for accurate measurements.

This thermometer is an environmentally friendly and safe alternative to traditional mercury instruments. It adheres to the rigorous standards of ASTM E1, E77, and E2251, ensuring it performs with the same accuracy and reliability as its mercury-based counterparts. The indicating fluid is a proprietary, biodegradable, non-toxic, and non-hazardous blue liquid. This dark blue fluid contrasts sharply against the white-backed stem, making it easy to read accurately and reducing the chance of measurement errors.

Features:

• ASTM Certified: Meets requirements for ASTM E1, E77, and E2251.
• Safe and Eco-Friendly: Uses a non-hazardous, biodegradable indicating fluid instead of mercury.
• High Visibility: The dark blue fluid is easy to read against the white-backed stem, ensuring clear readings.
• Versatile Application: While specified for tank testing, it is also acceptable for use in Saybolt Viscosity Testing and other general-purpose lab applications.

NIST Traceable Calibration: This thermometer includes a NIST Traceable Certificate of Calibration from an ISO/IEC accredited laboratory, providing you with confidence in its accuracy and reliability. The calibration is performed using a direct comparison method in a high-stability liquid bath against a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT). Each thermometer is meticulously inspected for cracks and liquid-column separations before testing. The certificate verifies its accuracy at five distinct temperature points across its range, ensuring dependable performance right out of the box.

Specifications:

• ASTM Number: S59F
• Temperature Range: 0°F to 180°F
• Immersion: Total
• Primary Application: Tank testing
• Division: 1.0°F
• Type: Liquid-in-Glass, Non-Mercury
• Length: 12.0in (305mm)

Care and Handling: To maintain the integrity and accuracy of the thermometer, it is essential to prevent fluid column separation. Always store Non-Mercury Thermometers in a vertical position using a dedicated storage rack. For use in ovens or other exposed environments, a Thermometer Well is recommended to provide physical protection and enhance thermal stabilization.
