Product Information
Full details
The Testo 810 is a 2-channel infrared thermometer ideal for HVAC technicians, electricians, and maintenance professionals needing quick, non-contact surface and air temperature measurements. Its key benefit is the simultaneous display of surface and air temperature, along with the temperature difference, simplifying diagnostics. A potential caveat is the need to adjust the emission level for accurate surface readings on different materials.

FAQs
What is the main advantage of the Testo 810?
The primary advantage is its ability to measure and display both surface and air temperature simultaneously, along with the temperature difference, providing quick diagnostic insights.
How do I adjust the emission level?
Refer to the user manual for specific instructions on adjusting the emission level, as it typically involves navigating through the device's menu settings.
What is the distance-to-spot ratio?
The distance-to-spot ratio (e.g., 4:1) indicates that at a certain distance, the measurement spot diameter will be a fraction of that distance. For a 4:1 ratio, at 4 feet away, the spot size is 1 foot.
Can I use this to measure the temperature of liquids?
The Testo 810 measures surface temperature. To measure liquid temperature, you would need to measure the temperature of a container's surface or a target placed in the liquid, not the liquid directly.
Is the TopSafe case waterproof?
The TopSafe case provides protection against dirt, impact, and moisture, but the device itself is not rated as waterproof. Avoid submerging the device or case in water.
What is the temperature range for this thermometer?
The operating temperature range is typically from -10 to +50 °C for ambient temperature and -30 to +250 °C for surface temperature. Please consult the official product specifications for precise ranges.
Troubleshooting
Device not powering on
Check that the batteries are inserted correctly and have sufficient charge. Replace batteries if necessary.
Inaccurate surface temperature readings
Ensure the emission level is set appropriately for the material being measured. Clean the lens. Verify the distance-to-spot ratio is suitable for the measurement.
Display is unreadable
Check battery level. Ensure the protective film has been removed from the display if applicable.
Laser pointer not visible
Check battery level. The laser pointer may be less visible in bright sunlight.
Pros and Cons
Pros
- Simultaneous surface and air temperature readings.
- Non-contact measurement for safety and convenience.
- Calculates temperature difference automatically.
- Durable construction with included protective case.
- Adjustable emission level for improved accuracy on different materials.
Cons
- Requires adjustment of emission level for optimal accuracy on various surfaces.
- Accuracy can be affected by surface reflectivity and emissivity.
- Not suitable for measuring the temperature of liquids without a suitable surface target.
Setup, Compatibility & Care
Setup: The Testo 810 requires no complex setup. Ensure the batteries are correctly inserted. Select the desired measurement mode (surface or air) and adjust the emission level if necessary for the surface being measured. For optimal results, aim the device so the laser spot covers the measurement area, and maintain the recommended distance-to-spot ratio (typically 4:1 for this model).
Compatibility: The device is designed for general temperature measurement and is compatible with most common materials. However, highly reflective surfaces may yield less accurate results unless the emission level is carefully adjusted.
Care: Keep the lens clean using a soft, dry cloth. The included TopSafe case should be used to protect the device during transport and use. Avoid exposing the device to extreme temperatures beyond its operating range or to corrosive substances. Clean the exterior with a slightly damp cloth if necessary; do not immerse in water.
