ASTM S9C Non-Mercury Thermometer: Precision, Safety, and Reliability

Introducing the ASTM S9C Non-Mercury Thermometer, a high-precision liquid-in-glass instrument designed for accurate temperature measurement in demanding laboratory and industrial environments. While offering physical and performance characteristics identical to their ASTM counterparts for referenced applications, these thermometers utilize a safe, environmentally friendly liquid, making them an ideal choice for modern safety protocols.

Uncompromised Performance, Enhanced Safety This thermometer features a vibrant, dark blue indicating liquid that is biodegradable, non-toxic, and non-hazardous, providing a clear and easily readable scale against the crisp white-backed stem. This innovative design eliminates the risks associated with traditional mercury thermometers without sacrificing accuracy or reliability. It's engineered to meet the stringent requirements of various applications, including:

• Pensky-Martens Closed Cup Flash Point Testing
• Tag Closed Cup Flash Point Testing

NIST Traceable Calibration for Ultimate Confidence Each ASTM S9C thermometer comes complete with a NIST Traceable Certificate of Calibration. This five-point calibration is performed by an ISO/IEC accredited laboratory, assuring you of the highest standards of accuracy and traceability. Our calibration process involves:

1. Rigorous Inspection: Before testing, each thermometer undergoes a thorough visual inspection for any cracks, liquid-column separations, or manufacturing defects.
2. Direct Comparison: Calibration is conducted in a high-stability liquid bath, where the thermometer is directly compared against a certified Precision Reference Thermometer (PRT) and a Standard Platinum Resistance Thermometer (SPRT).
3. Five-Point Measurement: Measurements are taken at five critical temperature points across the specified range, ensuring consistent and precise performance throughout its operational limits.

This meticulous calibration process guarantees that your measurements are accurate, repeatable, and compliant with relevant industry standards, providing you with absolute confidence in your results.

Key Specifications:

• ASTM Number: S9C
• Temperature Range: -5 to 110°C
• Immersion: 2.3 inches (57 mm)
• Division: 0.5 degrees
• Type: Non-Mercury (Biodegradable, Non-toxic, Non-hazardous)
• Length: 11.6 inches (295 mm)

Important Usage and Storage Recommendations: To maintain the integrity and accuracy of your Non-Mercury Thermometer, always store it vertically, preferably within a dedicated storage rack. This practice is crucial in preventing fluid column separation, which can impact measurement precision. For enhanced protection and thermal stability in challenging environments like ovens, consider utilizing a Thermometer Well. This accessory provides a controlled enclosure, shielding the glass from direct exposure and minimizing thermal fluctuations.
