Testo ε-Marker Emissivity Reference Stickers

Ever spent too long manually dialling in emissivity and reflected temperature on a thermal imager? The Testo ε-Marker reference stickers are designed to cut that setup time right down, letting your compatible Testo imager do the hard yards automatically. In Australian conditions, especially when dealing with varied surfaces, getting those thermal readings right is critical for accurate fault diagnosis, whether you're looking for electrical hotspots, insulation gaps, or moisture problems.

These small, precise markers simplify the most critical part of thermal imaging setup, getting you to the diagnosis quicker and with greater confidence in your data. It’s like having an extra pair of hands dedicated to precision.

Best For

• Thermal imaging technicians
• Electricians performing switchboard checks
• HVAC installers and service teams for building diagnostics
• Building inspectors and energy auditors

Compatibility

These ε-Marker stickers are specifically designed to work with Testo thermal imagers that feature the Testo ε-Assist function. This includes popular models such as the Testo 868, Testo 871, Testo 872, Testo 883-1, and their respective building diagnosis kits. If you're running a different model, check your imager's specifications to confirm ε-Assist compatibility before ordering.

Features

• Automatic Emissivity Detection: Your thermal imager automatically determines the emissivity (ε) of the measurement object.
• Reflected Temperature Setting: Automatically sets the reflected temperature (RTC) for enhanced accuracy.
• Fast Setup: Streamlines the thermal imaging process, saving time on site.
• Consistent Accuracy: Helps ensure reliable and repeatable thermal images, reducing human error.
• Convenient Pack Size: Supplied in a pack of 10 for multiple uses or jobs.

Technical Specifications

What's in the Box

• 10x Testo ε-Marker reference stickers (SKU: 0554 0872)

Using It on the Job

1. Prepare Surface: Ensure the measurement object surface where the sticker will be placed is clean, dry, and free from dust or grease.
2. Attach Sticker: Carefully peel and firmly attach one Testo ε-Marker to the measurement object within the area you intend to image. Ensure good, flat contact.
3. Power On Imager: Switch on your compatible Testo thermal imager with the ε-Assist function.
4. Point and Scan: Point your thermal imager towards the ε-Marker on the object. The imager will detect the sticker.
5. Automatic Setup: Allow the imager to automatically determine and set both the emissivity and reflected temperature. Confirm the settings on your imager's display.
6. Proceed with Imaging: Once parameters are set, you can proceed with capturing accurate thermal images of the surrounding area.

Limitations & Safety Notes

• Requires a Testo thermal imager that specifically includes the ε-Assist function for automatic detection.
• These markers are designed for single-use application per measurement session to maintain accuracy.
• Ensure the sticker is applied to a flat, clean, and representative surface of the material being measured for best results.
• Always refer to your thermal imager's operating manual for specific instructions on using the ε-Assist function.

Tradie Pro Tip

For really tricky surfaces like highly reflective metals, textured finishes, or materials with variable coatings, these ε-Markers are a genuine lifesaver. Stick one on, let the camera dial in, and you'll get reliable data every time without the guesswork, which is crucial for professional reports.

Pair With

These Testo ε-Markers are best paired with compatible Testo thermal imagers for comprehensive diagnostics. Consider adding a Testo Bluetooth humidity probe or a moisture meter for complete building condition assessments, or a set of Testo smart probes for HVAC system performance checks.
