Dial Thermometers
Using a dial thermometer is the easiest way to measure the temperature of your samples or solutions. Stainless steel thermometers with easy-to-read dials are rugged and suitable for a wide range of applications.
Choose between digital and analogue dial thermometer models with dual and single ranges. Moreover, with an external nut, calibration is easy. Let's see some of the different types of dial thermometers.
Types of Dial thermometers
Digital Dial thermometer
A digital dial thermometer has automatic shut-off, F°/C° switches, max/min settings, and hold settings, is made with corrosion-resistant construction and LCD display, making it an excellent choice for quick measurements. Various temperature ranges are available.
Single or dual range dial thermometer
Dial thermometers have dial faces with diameters of 1.75 inches (44.45mm), except MA-121 and MA-123P models, which have dial faces with diameters of 2 inches (50.8mm). Each model has a different temperature range and division. This MA-123 model features a glass crystal that can withstand oven temperatures as well as higher temperatures. Also available are polycarbonate crystals. Accuracy is ±1%. Adjustable mounting clips are available.
Pocket dial thermometers
Stainless steel type 304 dial cases are featured along with 0.15in (3.81mm) diameter stems on Pocket Dial Thermometers that are 5in (127mm) in length. With an accuracy of 1%, they cover a wide range of temperatures and divisions. It is made of rugged plastic and measures 1in (25.4mm) in diameter. Recalibration is easy with an adjustment nut. Plastic carry cases with clips are included with all models.
Pocket surface thermometers
When a pocket surface thermometer is placed on a horizontal surface, the temperature of the surface is measured. The mounting can also be done on ferrous surfaces other than horizontally due to the presence of two integral magnets. The dial faces show F° and C° divisions, which are accurate to 2%.
How to buy a right dial thermometer
Display Options
A dial thermometer can display the following information:
- With dual displays, you can choose between Fahrenheit and Celsius
- Readings between the minimum and maximum
The display of a digital thermometer is usually LCD or LED. In traditional dial thermometers, a metal needle on a round face indicates the temperature.
Size Characteristics
- Dial thermometers should have the following display or scale characteristics:
- A display's diameter. Dials or displays are commonly 1 to 5 inches in diameter
- The term probe refers to a variety of temperature sensors, used in a wide range of applications. Materials and sensitivities of probes can vary.
- Diameter and length of the bulb.
- Capillary length. The accuracy of capillaries is greater when they are shorter.
Dial displays
- Screens that display digital information
- Capillary tubes are flexible tubes that connect bulbs or sensing elements to displays. Only liquids, gases, and vapours can use this feature.
- It is possible to reset a zero adjustment thermometer.
- Max/min indication thermometers can record or indicate maximum and/or minimum values.
- Vibration-dampening thermometers use needles that absorb vibrations or shocks. Dial cavities are usually filled with liquid. Only mechanical needles can be dampened by vibration.
