IRThermo full
IRThermo with IRThermoDIN device

IRThermo is a software designed to use with IRThermoDIN, IRThermoUSB, IRThermoControl, and IRThermoLCD devices. It can configure a device language and measurement unit system on all devices. IRThermoDIN and IRThermoControl can be configured with the alarming behavior (visual and audio signals) and the relays. The current status of the configuration is also presented if the device is connected.

The configurations can be downloaded from the device and stored in local files for later examination or backup purposes.

The IRThermo software can make measuring. The data are stored as Comma Separated Values (CSV) and contain the measured time (seconds from the beginning of the measurement) and the measured values.

Supported devices

With IRThermo software You can use four devices:

  • IRThermoDIN
  • IRThermoControl
  • IRThermoLCD
  • IRThermoUSB

Installation and setup

You can download the program from the software repository. IRThermo is a freeware software, that can be installed on Windows 10 and 11. After the installation, You can start it from the Start Menu. At the left-right corner is the Connection part of the program. With a scan button, You can search for connected devices. Program language can be set from the same part. It supports 18 languages: English, German, French, Italian, Portuguese, Spanish, Dutch, Hungarian, Croatian, Slovenian, Serbian, Czech, Slovak, Polish, Danish, Swedish, Norwegian, and Finnish. After You have chosen the correct language, restart the program to take effect.

Loading the configuration can be done from a connected device or the file. An example of configuration files can be downloaded here. By connecting to the device, the current configuration of the device will be automatically loaded. If the device supports actions, like relays of alarms, it can be set up by Device configuration.

The actions can be set to Off, above, and below the value of the sensor. Triggering value is defined under the action part for the same control.

Example of a configuration for Relay 1 - Action Below, value 32 °C, Sensor Object

In this case, if the temperature of the object is under 32 °C, Relay 1 will be triggered. This setup can be done to activate some control if the object is colder of defined value.

Example of a configuration for Relay 2 - Action Above, value 62 °C, Sensor Air

In this case, if the temperature of the air is above 62 °C, Relay 2 will be triggered. This setup can be done to activate some control if the object is hotter of defined value.

Device language can be changed by drop-down menu, it supports the same 18 languages as the program: English, German, French, Italian, Portuguese, Spanish, Dutch, Hungarian, Croatian, Slovenian, Serbian, Czech, Slovak, Polish, Danish, Swedish, Norwegian and Finnish After You changed the language, You must save the configuration to the device. Measurement units can be configured as degree Celsius (°C) or degree Fahrenheit (°F).

Saving the configuration

After You made the configuration, You can save the setup to the connected device, or file. Saving to the device will take an immediate change of the configuration, is no need to restart the device after the new configuration is uploaded. By saving the setup to a file, You can always load it into a new device or examine it later. Saved configurations are stored as .cfg files.

If You made an incorrect setup, the program will warn You about it and will not write the miss-configured parameters into the device or to the file.

Device information and status

IRThermo device information
IRThermo device information

If the device is connected, in the left bottom corner is presented the Device information.

  • Program version
  • Device - the name of the connected device
  • Sensor - the type of the sensor
  • Hardware version - the version of the PCB and the case
  • Firmware version - main software of the device
  • Object - measured temperature of the object
  • Air - measured temperature of the air

On the top middle of the window can You see the Status

It shows the current language and the status of alarms and relays. These statuses are updated once a second.

In the lower part of the window can You see the Device ports and the photo of the device ports. Depending on the device, it can show You the power connection, the switching port, connectors for the sensor, relays, etc. On the right bottom side is the photo of the connecting side and the position of the ports, so You can easily find the ports.

IRThermo measurement

Measurements can be programmed in the right top corner. Before You can begin with measurement, You must choose how long will be measured. This can be defined with the Measurement time (minutes), minimal time is 1 minute. After You defined the duration, You must choose the file name, where they will be stored measured data. It will have a .csv extension.

The file is a textual file and can be edited with Notepad or any other text editor. The measured values are presented in the format:

time , object, air

An example of measurement:

15 , 56.25 , 26.11

That means that in 15. second of the measurement was 56.25 for object and 26.11 for air. It will store the values in .csv file in a unit (°C or °F) depended on the device configuration. With these values, You can generate graphics or other scientific data analyzes.
