Information on the calibration of newly purchased equipment and what it means to you.
Calibration and its certification comes in varying forms on new equipment and in this section, we will break it down into the three areas that we use to classify calibration state at the point of purchase.
Manufacturers Calibration Certificate
This is a calibration certificate offered by the manufacturer supplied with the tester. This is also known as an end-of-line certificate or manufacturer’s certificate. These certificates vary depending on the manufacturer and product. They will not have your company's name on them and don’t always show proven test results.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.Manufacturers Certificate of Conformity
A manufacturer's certificate of conformity is not a calibration certificate. It is merely a statement that the equipment has been produced to operate within its intended application, it has no traceable certificate or constitutes any defined results for accuracy before leaving the manufacturing process.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.Personalised traceable calibration certificate from isswww
This is a calibration certificate created by us at ISS. This certificate is fully traceable to national and international standards. The certificate will show your company's details, tester information, proven test results and the equipment used to carry out the test. Nearly 90% of all calibrations we do are done in-house in one of our many fully equipped laboratories. You can add this service to your order on the product page before you checkout.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
We are on occasion able to offer FREE calibration on certain products at their point of sale (newly purchased equipment only) please look out for the following badge on the product's page to take advantage of this free offer.

Fluke 820-2 LED Stroboscope
820-2 LED Stroboscope Comes Supplied With:
- Protective case
- External trigger connector
Investigate and observe potential mechanism failure with confidence
Identifying the running speed of rotating equipment can be difficult, but the Fluke 820-2 LED Stroboscope simplifies the process allowing you to perform stop motion diagnostics without actually stopping, or making contact, with the machine you are working on. Whether you are trying to diagnose parasitic oscillations, slippage, or unwanted distortions, the 820-2 LED Stroboscope is the ideal frontline troubleshooting, process or product research and development tool.
- High-intensity 7-LED array – 4,800 Lux @ 6,000 FPM/30cm
- High efficiency LED solid-state light source with uniform flash characteristics allows for higher flash rates – 30-300,000 FPM (flashes per minute)
- Digital pulse width modulation for exceptionally sharp images at high speeds
- Rugged, durable design utilizes solid-state LEDs with no filaments, gases, hollow cavities, or glass – (1 meter drop)
- Quartz-accuracy control system provides high accuracy – 0.02% (+/- 1 digit)
- Multi-line LCD display
- Check the rotating speed of machinery without physical contact or need for reflective tape
- Advance or retard flash timing for viewing gear teeth, cutting surfaces, repeats, or drifting equipment
- Simple push button operation with 2x and ÷2 buttons for easy adjustment
Adjustable flash duration
For most applications the standard flash duration will work well without adjustment. In other applications with higher rpm or larger rotating objects with high surface speeds, an adjustable flash duration is needed. In high speed applications, objects may move during the brief period of a single flash, resulting in a blurred image. By decreasing flash duration, objects have less time to move and the image will appear sharper.
Common applications for the 820-2
The Fluke 820-2 LED Stroboscope is more than just a tool to measure rotational speed of machinery without physical contact. It is also an excellent diagnostic tool for a wide variety of applications:
- Belt driven machines - HVAC fans, pumps
- Roller bearings, shafts, gear teeth or other machine components
- Clutches and cogwheels
- Foundations - resonance vibrations
- Cable or piping wear or damage
- Mixing and dosage processes
In addition, the LED stroboscope can be used as a strobe tachometer to measure speed instead of using a laser tachometer. In order to use the stroboscope, the component under measure must be visible, and have an identifying mark that can be used as a point of reference. A strobe tachometer is a useful tool because you can't always get access to the machine shaft to stick a piece of reflective tape to use a laser tachometer or make contact with the moving shaft to use a contact tachometer - using a stroboscope you can "stop" the shaft down to 30 RPM (FPM).
Use the 820-2 for:
- Turbines that vary in speed and change speed frequently
- Variable Frequency Drive motors that vary in speed, but do not change frequently
- Find belt rotation speed and look for belt slippage
- Find machine element components – fan blades, pump vanes, compressor screws, and gear teeth
- RPM measurement and frequency investigation
- Slip measurement
