Description – purpose of use

The Fortum® 4780401 Infrared Thermometer is used for non-contact measurement of surface temperatures of objects in the temperature range from -50 °C to +800 °C. Measurement with the non-contact thermometer is very fast and easy and it is thus possible to determine the temperature of objects which cannot be measured by means of contact (rotating shafts or products on a production line belt), furhermore live electrical conductors, food, liquids and items that are otherwise difficult to measure or hard-to-reach or distant.

THE NON-CONTACT THERMOMETER HAS THE FOLLOWING FUNCTIONS:

• Continuous temperature measurement.

• Display of max. measured temperature.

• Display of temperature on the display even after finishing measuring (“HOLD” function).

• Aiming laser can be turned on/off.

• Temperature units °C/°F.

• Adjustable emissivity for increased measurement accuracy of specific types of materials.

• Adjustable light notifications (“COLOUR ALARM”) for low or high temperatures.

• The supplied removable Type K temperature probe for a temperature range of -40 °C to 1000 °C can be used
  for making verification temperature checks within the temperature measurement range of the device -50 °C to
  +800 °C (the device can be used to measure temperature using the contact and non-contact method simultaneously).

• The aiming laser can be deactivated if necessary, and thanks to its circular projection, based on the distance of the device from the measured surface, enables the collection of information about the diameter of the measured surface, which is important for the measured temperature result not to be skewed by another background temperature relative to the 12:1 optical resolution of the device, which would result in measurement inaccuracies. The significance of the device’s optical resolution is described below.

• Intuitive colour display makes measurement and orientation on the display very clear.

The manually activated UV light source can be used to detect, for example, liquids from pipes containing compounds (substances) visible under UV light, or other substances and materials visible under UV light.

THE RELATIONSHIP BETWEEN THE DISTANCE OF THE DEVICE, THE DIAMETER OF THE MEASURED AREA AND MEASUREMENT ACCURACY

y The diameter of the measured area is given by the optical resolution of the device 12:1, which in practice means that the device at a distance of, for example, 300 mm from the measured area measures the temperature of an area with a diameter of 25 mm. This fact has a fundamental effect on the temperature measurement accuracy of the object when the size of the area of the measured object is small and the device is at a greater distance from the object than it should be with respect to the device‘s optical resolution of 12:1. In such a case, the non-contact thermometer measures alsothe background outside the measured object, which leads to measurement inaccuracies. To achieve measurement accuracy, it is necessary to take into consideration the size of the area of the measured object and the distance of the thermometer from the object with respect to the device‘s resolution of 12:1.

EMISSIVITY-INTENSITY OF RADIATION AND MEASUREMENT ACCURACY

• Emissivity expresses the ability of a material to emit infrared radiation. A majority of organic materials and laminated or oxidised surfaces have an emissivity value of approximately 0.95. Measuring the temperature of materials with a different emissivity value than 0.95 leads to inaccurate measurement results.

If you wish to increase measurement accuracy, set the device‘s emissivity value for the measured material according to table 3 provided below. During measurement, we recommend recording the set emissivity value for the given material to enable measurement results to be compared relative to the set emissivity for the given material.

3. Press the trigger to end the setting mode, and the set value will be saved for measurement.

Examples of setting temperature notifications:

1. „LAL“: 35 °C; the measured temperature is 31 °C; the indicator light will be lit red because the measured temperature is already below the low temperature notification limit.
2. „HAL“: 34 °C; the measured temperature is 31 °C; the indicator light will be green because the measured temperature is still below the high temperature notification limit.
3. „HAL“: 25 °C; „LAL“: 20 °C; the measured temperature is 24 °C; the indicator light will be lit green because the measured temperature is below the high temperature notification limit and has not reached the low temperature notification limit.

Measuring temperature

• When measuring temperature, use the aiming laser taking into consideration the size of the measured object and the distance of the device from the measured object so that the optical resolution of 12:1 is maintained, which is important for the accuracy of the measured temperature (see paragraph „The relationship between the distance of the device, the diameter of the measured area and measurement accuracy“).

1. Turn on the device and aim it at the measured area at a distance from the measured object  corresponding to the optical resolution of the device. During temperature measurement, the temperature measurement symbol (indicator) will be shown on the display, fig. 2, position 7.
2. Press and then hold down the trigger, then the measured temperature will be shown in the central part of the display. The max. measured temperature recorded during the measurement process will be shown in the bottom part of the display.
