ASTM S113C Non-Mercury Thermometer: Precision, Safety, and Traceability for Bituminous Testing

The ASTM S113C Non-Mercury Thermometer is engineered to deliver precise temperature measurements crucial for applications like Bituminous Softening Point testing, without the risks associated with traditional mercury thermometers. This robust instrument offers identical physical and performance characteristics to its ASTM-approved counterparts, ensuring reliable results in critical laboratory environments.

Key Features & Benefits:

• Mercury-Free Safety: Features a safe, blue indicating liquid that is biodegradable, non-toxic, and non-hazardous. This eliminates the environmental and health concerns of mercury, making it ideal for laboratories prioritizing safety and compliance.
• Enhanced Readability: The dark blue liquid stands out sharply against a white-backed stem, ensuring clear and immediate temperature readings, reducing potential for human error.
• NIST Traceable Calibration: Each thermometer arrives with a comprehensive NIST Traceable Certificate of Calibration. This five-point calibration is performed by an ISO/IEC accredited laboratory, guaranteeing that your measurements are backed by the highest standards of accuracy and international recognition.
• Rigorous Calibration Process: Calibration involves direct comparison in a high-stability liquid bath against a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT). Prior to testing, each thermometer undergoes meticulous inspection for cracks and liquid-column separations to ensure integrity.
• Total Immersion Design: Designed for total immersion, guaranteeing that the entire sensing portion of the thermometer is at the temperature being measured, leading to highly accurate and consistent results.

Technical Specifications:

• ASTM Number: S113C
• Temperature Range: -1 to 175°C
• Immersion: Total
• Application: Bituminous Softening Point testing, along with other industrial and research applications requiring this specific temperature range.
• Division: 0.5 degrees Celsius for precise readings.
• Type: Non-Mercury, liquid-in-glass.
• Length: 16 inches (410 mm)

Important Usage and Storage Information:

To maintain accuracy and prevent fluid column separation, always store non-mercury thermometers vertically. Utilize a dedicated storage rack for optimal protection and longevity. For added thermal stabilization and physical protection in ovens or other exposed environments, consider using a Thermometer Well.

This thermometer is an indispensable tool for quality control, research, and regulatory compliance in industries where accurate temperature monitoring is paramount.
