Why Choose the ASTM S58F Non-Mercury Thermometer?

This thermometer combines precision, safety, and convenience. The proprietary blue liquid is non-hazardous and maintains the same performance characteristics as traditional mercury thermometers, without the associated risks. Its durable construction ensures long-lasting performance, even in demanding environments.

Calibration and Quality Assurance:

Each thermometer undergoes extensive testing and calibration in an ISO/IEC-accredited laboratory. Calibration is performed at five distinct temperature points using cutting-edge equipment, ensuring unparalleled accuracy. Additionally, all thermometers are inspected for physical integrity, such as cracks or liquid-column separations, before shipping.

Storage and Maintenance:

To prevent fluid column separation, always store the thermometer in a vertical position, preferably using a storage rack. Proper storage ensures reliable performance and extends the lifespan of the device.

Optional Accessories:

• Thermometer Well: Provides additional protection and thermal stabilization for glass thermometers, particularly in ovens or exposed environments. This accessory ensures consistent temperature readings and minimizes risks of damage.

Whether you're conducting tank testing, viscosity measurements, or general laboratory work, the ASTM S58F Non-Mercury Thermometer offers a safe, accurate, and eco-friendly solution. Designed for precision and built to last, it's the ideal choice for professionals who demand the best.
