ASTM S62F-S70F Non-Mercury Thermometer Set, -36 to 761F NIST

Precision & Safety: ASTM S62F to S70F Non-Mercury Thermometer Set with NIST Calibration

Elevate your laboratory's accuracy and safety with the ASTM S62F to S70F Non-Mercury Thermometer Set. This comprehensive set offers a broad measurement range from -36°F to an impressive 761°F, making it an indispensable tool for a variety of applications requiring precise temperature monitoring. Each thermometer is designed for total immersion, ensuring maximum accuracy, and features varying graduations to suit specific testing requirements. With a uniform length of 15.7 inches (400mm), these thermometers are ideal for specialized applications such as precision full set testing, as well as general-purpose use within their impressive range.

Uncompromising Performance, Enhanced Safety

Our ASTM Non-Mercury Thermometers are meticulously engineered to meet the stringent requirements of standard test methods, delivering performance characteristics identical to traditional ASTM Mercury Thermometers. The key differentiator is the use of a proprietary, safe blue liquid indicator, offering a non-toxic, non-hazardous, and biodegradable alternative to mercury. This dark blue fluid provides exceptional visibility against the white-backed stem, ensuring quick and accurate readings without compromising safety.

Key Features & Benefits:

• Broad Temperature Range: Covers -36°F to 761°F, suitable for diverse laboratory needs.
• Total Immersion Design: Ensures superior accuracy by measuring the temperature of the entire liquid column.
• Non-Mercury Fluid: Features a safe, blue, biodegradable, non-toxic, and non-hazardous indicating fluid.
• High Visibility: Dark blue fluid against a white-backed stem for easy and clear readings.
• ASTM Compliance: Meets or exceeds ASTM E1, E77, and E2251 standards, ensuring reliability and conformity for critical tests.
• Specific Application: Acceptable for use in Saybolt Viscosity Testing, among others.
• Durable Construction: Designed for longevity in demanding laboratory environments.

NIST Traceable Calibration for Ultimate Confidence

Each lab thermometer in the set comes complete with a NIST Traceable Certificate of Calibration. This is not just any certificate; it's a five-point calibration performed by an ISO/IEC accredited laboratory. This accreditation signifies that your calibration is conducted under rigorously qualified and controlled conditions, adhering to the highest international standards.

The calibration process involves a direct comparison of the glass thermometer in a high-stability liquid bath against a certified Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT) with associated displays. Before testing, every thermometer undergoes a meticulous inspection for any cracks or liquid-column separations to ensure integrity. Measurements are precisely recorded at five critical temperature points across the instrument's range, providing a comprehensive and reliable calibration.

Care and Maintenance:

To maintain the accuracy and longevity of your non-mercury thermometers, always store them vertically using a specialized storage rack to prevent fluid column separation. For use in ovens or other exposed environments, a Thermometer Well is recommended to provide crucial protection and thermal stabilization, safeguarding your instruments from external factors and ensuring consistent readings.
