High-temperature measurement / Non-contact temperature measurement
With a handheld radiation thermometer
Efficient high-temperature measurement and recording
In situations where high temperatures are required for measuring equipment or metals, challenges include the need to approach the measurement location, manual recording of measurements, and the time-consuming process of organizing data after measurement. By utilizing a handheld radiation thermometer, temperatures can be measured without touching the object. Furthermore, by combining it with Bluetooth communication and data recording functions, the entire process from measurement to recording and management can be streamlined.
01
Common challenges in temperature measurement at high-temperature sites
In manufacturing environments, there are situations where it's necessary to check the temperature of objects that cannot be directly touched by humans, such as furnaces, heating equipment, and high-temperature metals.
When regularly measuring high-temperature objects like these, it's necessary to consider not only "measuring the temperature," but also the measurement process itself and the recording of the results afterward.
Approach to the high-temperature area
There are situations where contact-type temperature sensors are difficult to use, or where it is necessary to approach high-temperature areas for measurement.
Handwritten record of measurements
If you are writing down display from a measuring instrument onto paper or a checklist, this creates a separate recording task in addition to the measurement itself.
Data organization after measurement
In a system where measurements recorded on paper are entered into a PC, transcription and data organization are time-consuming processes.
Therefore, what we need to consider is improving both "how we measure" and "how we record" together.
02
radiation thermometer can measure temperature from a distance.
radiation thermometer is a non-contact thermometer that detects infrared radiation emitted from the object being measured and determines the temperature from its intensity.
Because it does not require the sensor to be in contact with the object being measured, unlike thermocouples or resistance thermometer, it is used for measuring the temperature of high-temperature objects, moving objects, and objects that are difficult to touch directly.
Non-contact does not mean that any object can be easily and accurately measured. With radiation thermometer, it is necessary to appropriately consider factors such as emissivity, measurement distance, measurement diameter, and the condition of the object being measured.
For those who want to learn more about radiation thermometer
The measurement principle, emissivity, measurement distance, and selection methods are explained in detail in the "radiation thermometer Guide".

It's not just about measurement, but also about "recording."
When choosing a handheld thermometer, people tend to focus only on the measurement range and accuracy. However, in environments where measurements are taken repeatedly on a daily basis, how to record the data after measurement is also important.
For example, in a system where an operator records the value display on a measuring instrument on paper and then inputs it into a PC, multiple tasks are involved: "measurement," "recording," and "input."
Measure
Point radiation thermometer at the object to be measured and take the temperature.
leave
The measured values are recorded on the main unit or connected devices.
Utilize
The recorded data is reviewed and organized on a PC or other device and used for quality control and equipment management.
The more frequently measurements are taken, the more important it becomes to design the operational process, including not only the performance of the measuring instrument itself but also the data recording process.
04
What changes with Bluetooth compatibility?
Bluetooth-enabled handheld radiation thermometer allow for wireless connection between the measuring instrument and compatible devices, enabling transfer of measurement data.
The IR-HA supports Bluetooth 5.0 Low Energy, and by using the Bluetooth option, measurement data can be handled on a smartphone or PC.
- Measurement data can be transfer wirelessly.
- Measurement data can be viewed on a smartphone or PC.
- This allows for more efficient recording and management of measurement results.
- We can consider implementing measures to reduce handwriting and transcription.
Especially in applications involving measurements taken at multiple locations, this provides an opportunity to re-evaluate the entire process of "recording the measured values on the spot."

Precautions when using radiation thermometer
radiation thermometer are convenient devices that can measure temperature without contact, but simply pointing them at the object to be measured does not guarantee that you will obtain the correct temperature.
emissivity
emissivity varies depending on the material and condition of the object's surface. Settings must be adjusted according to the object being measured.
Measurement diameter
radiation thermometer have a limited measurement range. Ensure that the object being measured is sufficiently larger than the measurement diameter.
Measured distance
The measurement diameter changes depending on the distance to the object. It is important to check the distance to be used and the size of the object to be measured.
Condition of the object being measured
Surface condition and measurement environment may affect the measurement results. Please select the appropriate equipment after checking the object and usage environment.
How to choose the right radiation thermometer
You can learn all the basics of non-contact temperature measurement, including emissivity, measurement diameter, and measurement distance.

What types of high-temperature measurements is it suitable for?
High-temperature handheld radiation thermometer like the IR-HA are suitable for measuring the temperature of high-temperature objects where it is difficult to install contact sensors or where you want to check the temperature from a distance.
Furnace/heating equipment
For checking the temperature of objects that reach high temperatures, such as inside furnaces and heating equipment.
Metalwork and heat treatment
For high-temperature measurements of heated metals and heat treatment process.
Inspection of high-temperature equipment
This is useful in situations where you want to check the temperature without directly touching the high-temperature area.
On the other hand, the appropriate radiation thermometer varies depending on the temperature range, material, surface condition, size, and measurement distance of the object being measured. It is important not to choose a model simply because it falls within the measurable temperature range, but to select one based on the overall measurement conditions.
High-temperature non-contact measurement and recording made more efficient.
The IR-HA handheld radiation thermometer supports non-contact measurement of high-temperature objects, as well as recording to an SD card and data sharing via Bluetooth.
Please consider the appropriate model and measurement method based on the measurement temperature, object, measurement distance, and recording method.
