Infrared Thermometer

The MS6530 The MS6530 is a type of high precision temperature measuring device know as an Infrared Non Contact Thermometer. There are many situations where contact with the object is undesirable, should be avoided or is simply not possible. For example, where surfaces are hazardous or are moving, where hygiene is an issue, where things are dangerous or inaccessible, in continuous industrial processes, and so on.

Infrared Thermometer Operating principle All surfaces emit thermal radiation. The type and amount of this energy can be used to determine the surface temperature of the object. The MS6530 detects radiation at infrared frequencies, in a narrow band from 8 to 14 micrometres, and focusses it onto a sensor. An internal microprocessor calculates and displays the temperature on an LCD screen. The laser is used only to indicate the target area to be measured. Laser light has no effect upon the measured temperature.

Inserting and Changing the Battery The unit requires a 9 Volt battery, type 6LR61. Perform the following procedure when you first receive the unit or when the battery low indicator shows (16). Pinch the OPEN characters on the unit handle (7), just below the trigger (6). The battery compartment hinges from the bottom of the handle. Clip the battery connector onto the top of the battery. Make sure that the battery polarity is correct. Connecting the battery the wrong way round may damage the unit. Press the battery into the handle. Position the battery cables inside the compartment. Clip the battery cover (7) back into place.

Measuring Temperatures Point the unit at the object to be measured. If desired you may press the laser button (2) to indicate the target area. Press and release the trigger (6). The temperature (14) of the object appears on the LCD screen. The LCD screen will hold the temperature for 7 seconds, indicated by the H symbol (13). If you need to measure temperature continuously just press and hold the trigger (6). The Scan indicator (18) on the LCD screen stays on. If require you can light up the screen up using the back light button (4).

Switching the Mode The LCD screen has a twin temperature display. The central reading shows the current value in large digits (14). The MODE button allows you to change the reading of the second, calculated value. Press the MODE button (3) to cycle through the options, Average (AVG), Maximum (MAX), Minimum (MIN), and difference between Maximum and Minimum (MAX-MIN).

Obtaining Accurate Measurements To obtain accurate and repeatable measurements you need to consider a range of variables. Most important are the D:S ratio and Emissivity. If you do not pay attention to these your readings may be inaccurate.

D:S Ratio Pressing the laser button (2) shows a ring of 12 laser spots and one central point. The Laser indicator (12) on the LCD screen stays on. As the distance (D) from the measured object increases so does the spot

Infrared Thermometer size (S). The ratio between these values is fixed at 12:1. For example at 1metre the spot size is 84millimetres wide, at 1.5 metres the spot size is 125millimetres.

For accurate readings the target should be larger than the visual spot size and should fill the field of view as indicated by the laser dots. For small targets you may have to be quite close.

Emissivity Emissivity is a crucial part of obtaining accurate and repeatable readings. Emissivity is a complex and difficult area. Objects made of different materials and with different surface finishes will have different emissivities. Emissivity also varies with frequency, some objects are transparent to certain frequencies but opaque to others. In the case of the MS6530 the emissivity is fixed at 0.95. Most organic materials and metal surfaces range between 0.85 and 0.98. 1.0 would be a theoretically perfect object, reflecting all the energy that fell on it. The result is that if the emissivity of an object measured with the MS6530 is less than 0.95 the reading will also be less than the true temperature of the object. If the emissivity is more than 0.95 the reading will be higher than the true temperature. Note that shiny or polished surfaces have low emissivity so your readings may also be correspondingly low.
