What is measurement?
Everyday, we measure temperature in various places and see the values.
So how is temperature measured?
Temperature is measured by the transfer of heat from an object to a sensor.
There are three ways that heat is transmitted to a sensor: conduction, radiation, and convection.
For example, when measuring body temperature, human heat is transferred directly to the thermometer sensor.
This is conduction, and since it comes into direct contact with the heat, it is called the contact type.
When measuring high-temperature objects such as molten iron or objects that are out of reach, you cannot bring a contact thermometer close.
In this case, a non-contact thermometer is used, which allows measurements to be taken without direct contact.
At CHINO, we manufacture contact temperature sensors (electrical type) that utilize thermal conduction and non-contact radiation thermometer that use thermal radiation radiation.
Temperature measurement involves transmitting heat to a sensor in a way that is appropriate for each and converting it into a numerical value.
There are various ways to convert the transmitted heat into a numerical value.
Typical contact types include the thermal expansion type and electrical type, and non-contact types include the radiant energy detection type.
Temperature control experts: Chino's measurements
Pushing the limits of measurement
Higher
High temperatures of over 3000°C can even melt iron.
It will melt and cannot be measured with a normal thermometer.
All objects emit infrared radiation.
By detecting the amount of infrared energy, we can measure temperature.
Measuring things that are so hot you can't even get close.
A thermometer that applies this principle is called radiation thermometer.
Chino is Japan's leading manufacturer of radiation thermometer.
Lower
Absolute zero (-273°C) cryogenic temperature all matter on Earth freezes and becomes motionless.
Chino uses platinum thermometers to enable the measurement of temperatures extremely close to absolute zero.
More precise
To measure temperature correctly, a thermometer must be accurately scale.
Chino offers standard platinum resistance thermometer based on the International Temperature scale of 1990 (ITS-90), which serve as the standard for all other thermometers.
It is thanks to the existence of these standard thermometers that everyone can measure temperature with confidence.
This is Chino's measurement technology.
