A curated collection of non mercury thermometer options from Thermco

Non-mercury thermometers are vital instruments in your kab, providing a safe and environmentally conscious alternative to traditional mercury-based thermometers. As laboratories increasingly prioritize safety and regulatory compliance, these thermometers have become indispensable across many disciplines. Whether it's measuring temperatures in chemical reactions, conducting quality control processes, or monitoring environmental conditions, non-mercury thermometers deliver precise and reliable results without the risks associated with mercury exposure.


We primarily stock Thermco thermometers. Thermco is well known for producing precision instruments that meet the rigorous demands of scientific research and industrial applications. Its commitment to excellence, combined with a wide range of non-mercury options, ensures that our customers receive reliable and environmentally safe thermometers. By choosing Thermco, we provide our customers with instruments that not only meet but often exceed regulatory standards, making them the preferred choice for labs focused on safety and precision.


Why does your lab prefer non mercury thermometers?

Our customers generally fall into a combination of three categories

Safety and environmental compliance

Non-mercury thermometers are designed to eliminate the health and environmental risks associated with mercury exposure. By using non-toxic substances such as alcohol or digital sensors, these thermometers provide a safer alternative, making them ideal for laboratories that must adhere to strict safety regulations. This shift is particularly important for labs working under guidelines set by the EPA and OSHA, where reducing hazardous materials is a key priority.

Accuracy and reliability

Non-mercury thermometers are engineered to deliver the same level of accuracy and reliability as traditional mercury-based instruments. These thermometers can provide precise, mercury-level temperature measurements, which is critical for processes where even slight deviations can impact results. Whether in chemical analysis, pharmaceutical testing, or environmental monitoring, non-mercury thermometers are up to the task.

Compliance with regulatory standards

Thermco non-mercury thermometers are designed to meet or exceed industry standards, including ASTM E1, which governs the accuracy and performance of liquid-in-glass thermometers. This compliance ensures labs using these instruments can trust their measurements and maintain compliance with industry regulations.


What's the difference between the blue fill and the red fill?

Aside from the color, not much. It's mostly about the conditions in your workplace


  • Blue spirit fill
    • Blue spirit thermometers typically use a dyed alcohol or a similar organic liquid that has been colored blue for visibility. The blue color is added to make the liquid column easier to read against the thermometer's scale.
    • These thermometers are commonly used in situations where precision is needed, but where extremely high or low temperatures are not expected. They are ideal for general laboratory use, educational settings, and some industrial applications.

  • Red spirit fill
    • Red spirit thermometers typically use a similar alcohol-based liquid but with a red dye. The red color is added for the same reason as in blue spirit thermometers - to improve visibility of the liquid column.
    • Red spirit thermometers are often used in more specific laboratory and industrial settings where slightly higher temperatures are measured, or where the red color offers better contrast for reading in certain environments.

What about all the other types of non mercury thermometers?

Liquid-in-glass thermometers aren't for all applications. So what does your application call for?


  • Digital thermometers

    Digital thermometers are highly versatile and user-friendly. They use electronic sensors to measure temperature and display the readings on a digital screen. These thermometers are known for their fast response time, high accuracy, and ease of data logging, making them ideal for laboratories that require frequent and precise temperature monitoring.


  • Infrared thermometers

    Infrared thermometers allow for non-contact temperature measurement by detecting infrared radiation emitted by objects. These thermometers are especially useful for measuring the temperature of surfaces that are difficult to reach or could be contaminated by contact.


  • Bi-metallic strip thermometers

    Bi-metallic strip thermometers operate by using two different metals that expand at different rates as the temperature changes. These thermometers are durable and reliable, often used in industrial settings for monitoring equipment and processes.


Each type of non-mercury thermometer serves a specific purpose, ensuring labs and industrial operators can choose the most suitable instrument for their temperature measurement needs.
