ASTM S62C to S70C Non-Mercury Thermometers -38 to 405C, NIST

ASTM S62C to S70C Non-Mercury Thermometers: Precision, Safety, and Traceability

Experience unparalleled accuracy and safety with our ASTM S62C to S70C Non-Mercury Thermometers. Engineered for precision and designed with environmental responsibility in mind, these thermometers offer a total measurement range from -38°C to 405°C, with varying graduations to suit diverse applications. Ideal for precision full-set testing and other critical measurements, these total immersion thermometers ensure reliable results every time. With a length of 15.7in (400mm), they are built to meet demanding laboratory and industrial requirements.

The Safe and Accurate Alternative to Mercury

These ASTM Non-Mercury Thermometers are developed to meet the rigorous standard test method requirements for their referenced applications, delivering performance characteristics equivalent to traditional ASTM Mercury Thermometers. However, they utilize a proprietary, safe blue liquid as a superior alternative to toxic mercury. This innovative fluid is:

• Biodegradable: Environmentally friendly and easily disposable.
• Non-toxic: Eliminates health risks associated with mercury exposure.
• Non-hazardous: Safe for handling and storage in any laboratory setting.
• Highly Visible: The distinct dark blue color is exceptionally easy to read against the white-backed stem, reducing eye strain and errors.

Key Features for Reliable Measurement:

• ASTM Compliance: Meets the stringent requirements of ASTM E1, E77, and E2251, ensuring adherence to recognized industry standards.
• Superior Readability: Dark blue indicating fluid provides crystal-clear readings against the contrasting white-backed stem.
• Environmental Responsibility: Features a non-hazardous, biodegradable liquid, making them a sustainable choice.
• Versatile Applications: Acceptable for use in critical procedures like Saybolt Viscosity Testing and other precision full-set applications.

NIST Traceable Calibration for Unquestionable Accuracy

Each thermometer comes complete with a NIST Traceable Certificate of Calibration. This certificate confirms a five-point calibration performed by an ISO/IEC 17025 accredited laboratory, guaranteeing the highest level of accuracy and traceability to national standards. This rigorous calibration process involves:

• Direct Comparison: Calibration is conducted in a high-stability liquid bath using a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT), ensuring precise temperature control.
• Comprehensive Inspection: Before testing, each thermometer undergoes a thorough inspection for any cracks or liquid-column separations that could affect accuracy.
• Multi-Point Validation: Measurements are performed at five critical temperature points across the thermometer's range, providing confidence in its performance over its entire scale.

This meticulous calibration process offers you peace of mind, knowing your measurements are consistently accurate and verifiable for auditing purposes.
