ASTM S9F Non-Mercury Thermometer, 20 to 230F, NIST

ASTM S9F Non-Mercury Thermometer, 20 to 230F, NIST

Discover precision and safety with the ASTM S9F Non-Mercury Thermometer. Designed for applications requiring a temperature range of 20 to 230°F, this thermometer is an ideal, eco-friendly alternative to traditional mercury thermometers.

Key Features:

• Safe & Eco-Friendly: Utilizes a biodegradable, non-toxic, and non-hazardous blue indicating liquid. This environmentally safe fluid eliminates the risks associated with mercury spills and disposal.
• High Visibility: The dark blue liquid stands out clearly against the white-backed stem, ensuring easy and accurate readings at a glance.
• Identical Performance: While not yet officially ASTM-reviewed, these thermometers are manufactured to have the same physical and performance characteristics as their mercury-based ASTM counterparts for referenced applications.

NIST Traceable Certificate of Calibration Included: Your thermometer comes with a NIST Traceable Certificate of Calibration from an ISO/IEC 17025 accredited laboratory. This certification guarantees that your instrument has been calibrated with the highest degree of accuracy against standards traceable to the National Institute of Standards and Technology (NIST).

• Rigorous Calibration Process: The thermometer undergoes a meticulous five-point calibration process. It is tested via direct comparison in a high-stability liquid bath against a Precision Reference Thermometer (PRT) and a Standard Platinum Resistance Thermometer (SPRT).
• Quality Assurance: Before calibration, each thermometer is thoroughly inspected for any physical defects, such as cracks or liquid-column separations, to ensure its integrity and reliability.

Product Specifications:

• ASTM Number: S9F
• Type: Non-Mercury
• Temperature Range: 20 to 230°F
• Division: 1.0°F
• Immersion Depth: 2.3in (57mm)
• Length: 11.6in (295mm)
• Application: Primarily for Pensky-Martens & Tag Closed Cup flash point tests.

Proper Care and Use: To maintain the accuracy and integrity of the indicating fluid, always store non-mercury thermometers vertically in a dedicated storage rack. This helps prevent fluid column separation. For use in ovens or other exposed environments, consider using a Thermometer Well to provide additional protection and thermal stabilization.
