The common types of laboratory thermometer include liquid-in-glass, a bimetallic strip, infrared, and electronic devices and their benefits.
The name thermometer comes from joining two Latin words: ‘thermo’, which means heat, and ‘meter’, which means measuring equipment. Most of us are familiar with the conventional mercury thermometer and the relatively newer digital thermometers practiced by doctors and nurses. However, there are different types of thermometers for use in different environments for different purposes. They are usually a liquid-in-glass device, a bimetallic strip, or an infrared (IR) device and Thermistor. These thermometer measure temperature with a high level of accuracy for some applications such as materials tests, research monitoring, and instrument calibration, etc.
At Laboratory Thermometer Manufacturer in Haryana, we believe it is important to know the types and benefits while selecting to suit your intended application. So let’s take a look at the different thermometers, we at H L scientific Industries offer and their ideal uses.
Different Types of Thermometers
Liquid-in-glass thermometers come in the categories of laboratory glassware. It is the simplest and most common type of temperature measurement device and is considered one of the best thermometers obtainable in the industry. Within the temperature range of -200 to 600°C, it gives fairly precise results. The liquid in the glass thermometer has a glass bulb attached to a sealed glass tube. This can be easily identified through its long stem consists of a silver bulb (mercury) at its bottom. Additionally, liquid-in-glass thermometers carry red alcohol; its liquid content in certain thermometers evaporates instantly.
Main benefits associated with the application of liquid-in-glass thermometers:
- Cheaper than other temperature measurement devices handy and convenient to use
- No requirement of power supply or batteries for charging
- Mercury thermometers give exact temperature readings and can be practiced orally, rectally, or under the arm.
An infrared thermometer employs thermal radiation that things emit to measure temperature, which means that they can show temperature from a distance. This type of infrared thermometer is for the fast, non-contact measurement of the surface temperature. It is a simple temperature measurement, also with dynamic processes or in locations that are challenging to access. This type of thermometer consists of a lens to focus the infrared (IR) energy on to a detector, which changes the energy to an electrical signal that can be represented in units of temperature.
The Infrared thermometer benefits are:
- Operate well for a variety of applications
- Memory and advanced measurement functionality
- Measurements can also be taken of moving parts
- Compact, lightweight, and easy to use
Bimetallic Strips are perfect for higher temperatures as they become less sensitive and accurate at lower temperatures. They can be obtained in many household apparatuses like stoves. A bimetallic strip is made up of two metals, having different thermal expansion co-efficient and bonded together. These bimetallic strips are sensitive to change the temperature and it causes mechanical displacement which helps to measure the temperature.
Some benefits of bimetallic thermometer benefits are
- Installation is easy
- Simple maintenance and less cost
- Accuracy is a good and linear response
- The temperature range is wide
- Robust and simple
Thermistors consist of sensitive resistors which are very specific and cost-effective sensors for measuring temperature. Thermistors are used as temperature sensors. They can be found in common appliances such as fire alarms, ovens, and refrigerators. Also, are used in digital thermometers and in various automotive applications to measure temperature.
Some Advantages of Thermistor Thermometers:
- Easy to miniaturize
- Fast response time
- Easy to use
