ASTM S47F Thermometer 137.5 to 142.5F, NIST Calibration

ASTM S47F Non-Mercury Thermometer: Precision and Safety Combined

Experience precise temperature measurement with our ASTM S47F Non-Mercury Thermometer, meticulously calibrated to NIST standards. This innovative thermometer offers all the physical and performance characteristics of traditional ASTM models, but with a crucial upgrade in safety.

Key Features & Benefits:

• Eco-Friendly & Safe: Utilizing a non-toxic, biodegradable, and non-hazardous blue indicating liquid, this thermometer eliminates the risks associated with mercury, making it ideal for a wide range of laboratory and industrial applications. The dark blue liquid ensures clear, easy-to-read measurements against the white-backed stem.
• NIST Traceable Calibration: Each thermometer comes with a comprehensive NIST Traceable Certificate of Calibration. This 5-point calibration is performed by an ISO/IEC accredited laboratory, guaranteeing accuracy and reliability. Our rigorous calibration process involves direct comparison in a high-stability liquid bath using a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT). Before calibration, every thermometer undergoes a thorough inspection for any cracks or liquid-column separations.
• Designed for Kinematic Viscosity: Specifically engineered for kinematic viscosity applications, this thermometer provides highly accurate readings essential for critical testing environments.
• Optimal Temperature Range: With a precise range of 137.5 to 142.5°F and a fine division of 0.1 degrees, it offers the granularity needed for sensitive measurements.
• Total Immersion: Designed for total immersion, ensuring accurate readings by placing the entire column of liquid in the substance being measured.
• Durable & Convenient Size: Measuring 12.6 inches (320mm) in length, it's built for durability and ease of use in laboratory settings.

Technical Specifications:

• ASTM Number: S47F
• Temperature Range: 137.5 to 142.5°F
• Immersion: Total

Important Care Instructions: To maintain the integrity of the fluid column and ensure consistent accuracy, always store Non-Mercury Thermometers vertically. We recommend using a dedicated storage rack to prevent liquid column separation. For enhanced protection and thermal stabilization when used in ovens or other exposed environments, consider utilizing a Thermometer Well.
