MUNRO provides a wide range of Temperature Meters / Thermometers for laboratories and industry. Thermometers are used for temperature measurement in many industrial applications.
What Are Thermometers?
Temperature measurements are critical for a variety of reasons. This concept started with Galileo Galleli, and now we have the first modern thermometer established in 1709 by renowned scientist Daniel Fahrenheit. He defined the freezing and boiling points of water as different temperatures. The thermometers now are much more complex in design due to scientific and technological breakthroughs. Modern thermometers are based on a variety of thermometric techniques, with infrared thermometers being quite common.
Applications of Thermometers:
- Laboratory: These thermometers are used for a variety of purposes in the laboratory, and they come in a huge variety. Probe Laboratory thermometers are particularly useful for the measurement of semi-solid materials and liquids. Infrared thermometers are perfect for non-contact readings of very high or incredibly low surface temperatures, depending on the application. The k-type thermocouples are specialized meters accessible for monitoring severe temperatures.
- Geographical application: Interior and outdoor temperatures, and heat movement can be measured with thermometers. Temperature measurements that range from the thermostat to alcohol thermometers have been critical in weather forecasting, meteorology, aviation engineering, and traffic monitoring. Indoor thermometers too are important in heating, ventilation, air conditioning as well as climate control systems (HVAC).
- Food: Prevention of foodborne diseases, bacterial development, and overcooking can be done by monitoring cooking and refrigeration systems with
food thermometers. Interestingly, other necessary instruments include candy thermometers and temperature indicator labels.
- House: It is critical to monitor temperature fluctuations in one's home to guarantee wellness and thermal comfort.
- Medical applications: various types of thermometers are available using a variety of thermometric technologies. Some include thermometers for forehead, ear, oral, underarm, and even rectal. Historically, the liquid used in glass units had been mercury, which may be quite dangerous. Now we have other techniques that include plastic strips, infrared, liquid crystal, and mercury-in-glass.
Thanks to decades of improvements in thermometric technology, today's customers may pick from a variety of models on the basis of a variety of technologies. Having stated that, potential purchasers should weigh three critical factors: needs, specifications, and overall prices, including accuracy, readability, and safety acting as critical benchmarks.
Given the critical nature of temperature readings, it's obvious that contemporary thermometers are indispensable and in high demand in fields such as research, health, food preparation, and industries.
Remember these while choosing a Thermometer:
While there are several thermometers, applications, and measurement methodologies available, the three most critical criteria potential purchasers should examine are the following:
Specs, necessities, and total expenditures
- Specs:
A critical aspect to keep in mind is accuracy. For the thermometer to be regarded dependable, it must have rapid readings and frequent updates, and steady successive measurements. Ambient temperatures shouldn't affect the thermometers. The other critical element to consider is readability. Ideal readings taken should be shown in both Celsius as well as Fahrenheit scales. The display should be easy to understand. When purchasing quick thermometers for food testing, customers should search for probes made of stainless steel or another high-quality material to prevent contamination.
- Necessities:
The purpose for which a thermometer is needed, such as utilizing special tools in industrial sites and laboratories, inspecting food, body temperature measurement, home temperature monitoring and more. Each variety of thermometers has distinct benefits, prices, and operating temperatures. It's also critical to choose between analog and digital versions.
- Total expense:
There are some types of thermometers that are more expensive than the others. Make sure you know your requirements and find them according to your budget.
History of Thermometers
Even after the advancement of thermometers, a few temperature scales of the 18th-century, especially Fahrenheit and Celsius, are used majorly. Daniel Fahrenheit directed the water's (BP) boiling point to 212 degrees as well as the freezing point to 32 degrees. In 1742, another physicist, Anders Celsius, invented the first centigrade scale and assigned the BP of water to zero degrees along with the (MP) melting point of snow to 100 degrees.
In 1742, Anders Celsius devised the first centigrade scale, which placed the boiling temperature of water at zero degrees and snow's melting point at one hundred degrees. Currently, the Celsius scale has been widely used around the globe, with 0 degrees representing the coldest temperature and 100 degrees representing the hottest temperature. It's interesting to note that at -40 degrees Fahrenheit, both Fahrenheit & Celsius are equivalent.

The scales known as the scales of Kelvin and Rankine are two more often used scales. William Thomson or Lord Kelvin of the United Kingdom suggested a scale in 1848 that was based on the Celsius scale but with a key that pointed to absolute zero, i.e., 273.15°C. The Fahrenheit scale, established by William Rankine, was keyed to absolute zero, i.e., 459.67°F. This was utilized by the Rankine scale by William Rankine. It should be noted that absolute zero is the lowest theoretical temperature possible while no heat energy exists in the substance.
