ASTM Equivalent S39C Non-Mercury Thermometer, 48 to 102C

ASTM Equivalent S39C Non-Mercury Thermometer, 48 to 102°C

Product Overview: This high-precision liquid-in-glass thermometer offers performance and characteristics equivalent to ASTM-certified instruments for its specified applications, though it has not yet received official ASTM review and acceptance. Designed as a safer, environmentally conscious alternative to traditional mercury thermometers, it utilizes a proprietary blue indicating liquid. This liquid is biodegradable, non-toxic, and non-hazardous, ensuring safety in laboratory and industrial settings. The distinct dark blue column provides exceptional readability against its white-backed stem, reducing eye strain and improving accuracy during measurements.

Key Features & Specifications:

• ASTM Equivalence: S39C (Note: Physical and performance characteristics are identical to ASTM standards for referenced applications).
• Temperature Range: Precisely calibrated for 48°C to 102°C, making it ideal for specific heating and distillation processes.
• Immersion: Partial immersion type, requiring 3.9 inches (100mm) immersion for accurate readings, indicated by a precise immersion line.
• Primary Application: Specifically engineered for Solvents Distillation, ensuring reliable temperature monitoring during critical phases.
• Division: Fine 0.2°C graduations allow for highly accurate and repeatable measurements, crucial for scientific and industrial compliance.
• Type: Non-Mercury, featuring a safe, eco-friendly blue organic liquid fill.
• Overall Length: A substantial 15.7 inches (400mm) for reach into various apparatus.
• Regulatory Compliance: Meets the stringent requirements of ASTM E2251, ASTM E77, and ASTM E1 test methods, providing confidence in its performance.

Usage and Storage Recommendations: To maintain optimal performance and prevent fluid column separation, always store non-mercury thermometers vertically. Utilize a dedicated storage rack to ensure proper orientation and protection. For enhanced durability and thermal stability in challenging environments like ovens or exposed setups, consider using a Thermometer Well. This accessory shields the glass thermometer while ensuring accurate temperature sensing.
