ASTM S67F Non-Mercury Thermometer, 203 to 311F, NIST

ASTM S67F Non-Mercury Thermometer, 203 to 311F, NIST

The ASTM S67F Non-Mercury Thermometer is a high-precision instrument designed for accurate temperature measurement in various laboratory and industrial applications. Engineered to meet rigorous ASTM standards, this total immersion thermometer offers a broad measurement range of 203°F to 311°F, with fine 0.5°F graduations, making it ideal for precision testing and critical processes where exact temperature readings are paramount. Its robust construction and innovative non-mercury fill ensure both performance and safety.

Advanced Non-Mercury Technology:

Distinguishing itself from traditional mercury thermometers, the S67F utilizes a safe, blue-colored liquid as an indicating fluid. This proprietary formula is not only biodegradable, non-toxic, and non-hazardous, but it also delivers the same high-performance characteristics and accuracy as ASTM Mercury Thermometers. The dark blue fluid stands out brilliantly against the thermometer's white-backed stem, ensuring effortless readability even in varying light conditions. This makes it an environmentally responsible choice without compromising on precision or reliability.

Key Features & Benefits:

• ASTM Compliance: Fully meets the stringent requirements of ASTM E1, E77, and E2251 standards, guaranteeing quality and consistency.
• Eco-Friendly & Safe: Contains a non-hazardous, biodegradable, and non-toxic indicating fluid, providing a safer alternative to mercury.
• Superior Readability: The high-contrast dark blue fluid against a white stem ensures quick and accurate readings.
• Versatile Application: Acceptable for use in specialized applications such as Saybolt Viscosity Testing, highlighting its versatility.
• Precision Measurement: Total immersion design ensures the most accurate temperature readings by immersing the entire liquid column in the substance being measured.
• Durable Construction: Built for demanding environments, offering reliable performance over extended use.

NIST Traceable Calibration for Ultimate Assurance:

Each ASTM S67F Non-Mercury Thermometer includes a comprehensive NIST Traceable Certificate of Calibration. This certificate is issued by an ISO/IEC accredited laboratory, providing verifiable assurance that the calibration process adheres to the highest industry standards. The calibration involves a meticulous five-point verification process performed in a highly stable liquid bath. During this process, the thermometer is directly compared against a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT) with associated displays. Before calibration, each thermometer undergoes a thorough visual inspection for any cracks or liquid-column separations, ensuring its integrity and accuracy from the outset. This detailed calibration guarantees the thermometer's reliability and its ability to provide consistently accurate measurements traceable to national standards.

Important Storage Information:

To maintain the accuracy and prevent fluid column separation, it is crucial to always store Non-Mercury Thermometers vertically. Utilizing a dedicated storage rack is highly recommended to ensure proper vertical orientation. For added protection in ovens or other exposed laboratory environments, consider using a Thermometer Well, which not only shields the glass thermometer but also aids in thermal stabilization, leading to more consistent readings.
