ASTM S62F Non-Mercury Thermometer, -36 to 35F, NIST

ASTM S62F Non-Mercury Thermometer, -36 to 35°F, with NIST Calibration

The ASTM S62F Non-Mercury Thermometer is a high-precision, environmentally conscious instrument designed for a wide range of laboratory and industrial applications. Engineered to provide accurate temperature readings from -36°F to 35°F (-38°C to 2°C), this thermometer features precise 0.2°F (0.1°C) divisions, making it ideal for critical measurements.

Unlike traditional mercury thermometers, the S62F utilizes a proprietary, biodegradable, non-toxic, and non-hazardous blue liquid as its indicating fluid. This innovative fluid offers the same high performance and reliability as mercury while eliminating the associated health and environmental risks. The dark blue liquid stands out clearly against the thermometer's white-backed stem, ensuring excellent readability and reducing the chance of reading errors.

Designed for total immersion, this thermometer is specified for use in precision testing where the entire indicating column needs to be at the temperature being measured to achieve maximum accuracy. Its robust construction makes it suitable for demanding environments, and its total length of 15.7 inches (400 mm) provides ample reach.

Key Features:

• ASTM Compliance: Meets stringent ASTM E1, E77, and E2251 requirements, ensuring suitability for standardized test methods.
• Eco-Friendly: Features a non-hazardous, biodegradable, and non-toxic indicating fluid, providing a safe alternative to mercury.
• High Visibility: The dark blue fluid is exceptionally easy to read against the white-backed stem, minimizing eye strain.
• Precision Measurement: Offers fine 0.2°F (0.1°C) divisions for accurate and reliable temperature readings.
• Total Immersion Design: Optimized for applications requiring the entire sensing portion to be immersed for maximum accuracy.
• Versatile Applications: Acceptable for use in specialized tests like Saybolt Viscosity Testing, as well as general laboratory and industrial use within its range.
• Individual Serial Number: Each thermometer is assigned a unique serial number for complete traceability.

NIST Traceable Certificate of Calibration Included: Every ASTM S62F thermometer comes complete with a NIST Traceable Certificate of Calibration. This certificate signifies that the thermometer has undergone a five-point calibration by an ISO/IEC 17025 accredited laboratory. This accreditation guarantees that the calibration process adheres to the highest international standards, performed in a qualified and controlled environment. The calibration involves direct comparison in a high-stability liquid bath against certified Precision Reference Thermometers (PRTs) and Standard Platinum Resistance Thermometers (SPRTs). Before testing, each thermometer is rigorously inspected for any defects such as cracks or liquid-column separations to ensure optimal performance from the start.

Important Storage Information: To prevent fluid column separation and maintain the accuracy of your Non-Mercury Thermometer, it is crucial to store it vertically using a dedicated storage rack. Consider utilizing a Thermometer Well for additional protection and thermal stabilization when using the thermometer in ovens or other exposed environments.
