ASTM S17F Non-Mercury Thermometer: Precision Measurement with Enhanced Safety

Introducing the ASTM S17F Non-Mercury Thermometer, engineered for precise temperature measurement in demanding applications, without the risks associated with traditional mercury devices. This liquid-in-glass thermometer offers the same physical and performance characteristics as a standard ASTM thermometer for Saybolt Viscosity applications, providing reliable data collection while prioritizing safety and environmental responsibility.

Advanced Non-Mercury Design: Unlike conventional thermometers, our S17F utilizes a unique, safe blue indicating liquid. This specialized fluid is biodegradable, non-toxic, and non-hazardous, making it an environmentally friendly choice and significantly reducing concerns over accidental breakage. The vibrant dark blue color contrasts sharply against the white-backed stem, ensuring quick and accurate readings even in challenging conditions.

Unwavering Accuracy with NIST Traceable Calibration: Each ASTM S17F thermometer comes with a comprehensive NIST Traceable Certificate of Calibration. This 5-point calibration certificate is issued by an ISO/IEC 17025 accredited laboratory, guaranteeing that your instrument meets rigorous international standards for quality and accuracy. The calibration process involves direct comparison in a high-stability liquid bath against highly precise reference instruments, including Precision Reference Thermometers (PRTs) and Standard Platinum Resistance Thermometers (SPRTs). Before testing, every thermometer undergoes meticulous inspection for any potential cracks or liquid-column separations, ensuring flawless performance from the outset.

Key Specifications:

• ASTM Number: S17F
• Temperature Range: 66 to 80°F (19 to 27°C) – Ideal for specific viscosity measurements.
• Immersion: Total – Designed for complete submersion, ensuring the entire liquid column reaches the measured temperature for maximum accuracy.
• Application: Saybolt Viscosity – Specifically calibrated for measuring the viscosity of petroleum products and lubricants.
• Division: 0.2° – Provides fine-grained temperature resolution for critical applications.
• Type: Non-Mercury – Safe, eco-friendly, and easy to dispose of.
• Length: 11 inches (280mm) – Standard laboratory length for versatility.

Optimal Care and Protection:

To maintain the integrity of the fluid column and prevent separations, always store Non-Mercury Thermometers vertically. We recommend utilizing a dedicated storage rack to ensure proper upright positioning and protection. For enhanced durability and thermal stability in high-heat or exposed environments like ovens, consider pairing your thermometer with a Thermometer Well. This accessory provides robust protection while ensuring accurate thermal transfer to the thermometer.
