Stargloss:
Gloss and Haze measurement is essential where an aesthetic appearance of the coating finish is required and to ensure uniformity of the surface finish.
The gloss value is determined by directing a light, which has a similar wavelength to the human eye, at the test surface and measuring the amount of specular reflection. Gloss is measured with angles of 60° and 20°.
The 60° angle is universal for all applications. The 20° angle gives improved differentiation of measurement on high-gloss coatings above 70 gloss units.
Haze measurement is required where high-gloss surfaces have a low reflection contrast. The Haze measurement is the difference between readings taken with the 20° and 60° angles, complying with International Standard ASTM D4039. The Stargloss will automatically calculate the Haze reading.
The Haze function is only available on combined 60°/20° models.
Small and portable, the Stargloss is one of the most advanced Gloss Meters available. By using tungsten halogen lamps and optical filters the light source has a similar spectro-response to the human eye, giving true human photo-optic performance, which is essential for ensuring exact compliance to International Standards.
Optical bench accuracy and stability are obtained by the optics being set in a precision-engineered aluminium block.
Available in models of Standard and Top. All functions are easily accessible through a menu-driven back-lit display.
Standard Models:
Calibration:
Calibrate on the supplied Gloss Standard or any other value Gloss Standard.
Statistics:
Continually shows Mean, Number of Readings, Max / Min, Coefficient of Variation and Standard Deviation.
Hi / Lo Limits:
Pass and fail with audible and visual alarm.
Top Models:
Calibration:
Calibrate on the supplied Gloss Standard or any other value Gloss Standard.
Statistics:
Continually shows Mean, Number of Readings, Max / Min, Coefficient of Variation and Standard Deviation.
Hi / Lo Limits:
Pass and fail with audible and visual alarm.
Batching:
Measurements that are taken can be stored into batches which incorporate batch number, unique job number, and date and time. You can also go back to previous batches and look at the statistics and add or cancel readings from previous batches.
Download:
Allows all measurements, statistics and out-of-limit readings to be downloaded to a computer either by batch number or job number into Microsoft Word or Excel. Your company name can appear on every download if required.

All models are supplied in an Industrial Foam-Filled Carrying Case with Gloss Standard and Charger. Top Models also come with USB Download Cable and Download Software.
Operation:
Switch On / Off:
To switch the Stargloss on, press the On / Off keypad for approximately 1 second. The display will show the last reading taken. The instrument will automatically switch off after approximately 5 minutes if no readings have been taken.
The instrument can also be switched off by pressing the On / Off keypad again.
Taking Readings:
Observe the location of the oval measuring hole (25mm x 12mm) located on the base of the instrument, which is the location where the gloss readings will be made. The location is identified by the arrows on the front and each side of the case.
Place the Stargloss onto the object to be measured and press the Read keypad. The reading will be held on the display until another reading has been taken.
Always ensure that the surface being measured is flat, and large enough to cover the oval measuring hole.
Readings on the same surface can vary if the light angle onto the surface is changed (the light source is from the left when looking at the front of the Stargloss).
Menu:
|
All functions are accessed through a menu-driven display in the categories shown below. To scroll through the menus use the up and down arrows and enter where you see the arrow symbol on the right of the display. When you are in the Menu and you want to exit, press the Menu button again and the instrument will revert back to normal measurement mode. |
|
This function is only available on combined 20 / 60 / Haze models. On Stargloss Top Models with batching turned on, when the angle is being changed there will be a request for Enter Job No, as different angles cannot be contained in the same batch. |
|
Angle : |
|
|
Select 60° |
The 60° angle is universal for all applications. |
|
Select 20° |
The 20° angle gives improved differentiation of measurement on high-gloss coatings above 70 gloss units. |
|
Select Haze |
Haze measurement is required where high-gloss surfaces have a low reflection contrast. |
|
Calibration |
Always ensure that the Gloss Standard and the base of the Stargloss are clean before calibrating. To clean the Gloss Standard, wipe with a soft paper towel moistened in warm water containing a small amount of detergent, then wipe dry with a soft paper towel. |
|
Operator Cal |
For the highest accuracy of measurement, the Stargloss has a variable calibration facility. The calibration is carried out by placing the Stargloss in the Gloss Standard ensuring that the measurement area is correctly located on the gloss tile. Calibration can then be carried out by entering the Gloss Standard value. |
|
Factory Cal |
When selected this will reset the instrument to a standard calibration. If you are using a combined 60° / 20° / Haze instrument, the calibration is only reset to the angle that you have selected. The Gloss Standard is not required for this calibration. Limit settings, if selected, will be cleared. |
|
Clear Memory |
Clears the instrument memory of all batches and stored readings. Does not affect calibration values. |
|
Statistics |
At any time the appropriate Statistics can be displayed on the lower line of the display. The Statistics will be automatically updated when additional readings are taken. |
|
Mean |
Average of all readings. |
|
Number Readings |
Number of readings taken. |
|
SDV |
Standard Deviation of readings taken. |
|
Coefficient |
Coefficient of variation of readings taken (SDV/Mean)*100. |
|
Maximum |
Maximum reading. |
|
Minimum |
Minimum reading. |
|
Statistics Off |
Removes the displayed Statistics. |
|
Batching |
This function is only available on Stargloss Top Models. Multiple batches can be stored to a maximum of 10,000 readings. |
|
Batch Store |
Readings taken can be stored in a batch and a job number allocated (up to 12 digits). Multiple batches can be stored with a maximum of 100 readings per batch. The 100th reading taken will automatically enter into a batch and you will be asked to enter the job number. |
|
Batch Recall |
Previous batches stored can be recalled either by batch number or by job number, so that further readings can be added. Statistics viewed or job number can be changed. |
|
Auto Batch |
A batch quantity can be allocated and the instrument will automatically enter the batch and you will be asked to enter the job number when this quantity of readings has been taken (the maximum batch limit is 99 readings). |
|
Batching On/Off |
Always ensure that Batching is On if you need to store readings. When you do not need to store readings switch the Batching Off. This will allow you to take readings further than 100 without automatically being stored into a batch. When changing angles on 60° / 20° / Haze instruments with Batching On, your readings will automatically be entered into a batch and you will be asked to enter the job number. |
|
Download |
This function is only available on Stargloss Top Models. This enables the batches stored to be downloaded to a computer with the Paint Test Equipment Downloader installed. Connection is made using the USB Cable (download instructions are available on the Help file in the program). The batches downloaded can then be entered into Word or Excel. |
|
By Batch Number |
Download single or multiple batches by batch number. By entering a zero batch, all batches will be downloaded. |
|
By Job Number |
Download single or multiple batches by job number. |
