1. Introduction
This manual provides essential instructions for the safe and effective use of the Testo 0560 8312 830-T1 IR Thermometer. This device is designed for non-contact measurement of surface temperatures in various industrial and trade applications. It features 12:1 optics and a dual laser for precise targeting, allowing for accurate temperature readings even on smaller objects from a safe distance.
2. Safety Information
Please read this section carefully before operating the device to ensure safe and proper use.
- Do not point the laser directly into eyes or at other people.
- Do not use the device in explosive atmospheres.
- Protect the device from extreme temperatures, impacts, and strong vibrations.
- Keep the device clean and dry.
- Only use the device for its intended purpose as described in this manual.
- Repairs should only be carried out by authorized personnel.
3. Product Overview
The Testo 830-T1 IR Thermometer is a handheld device designed for quick and accurate non-contact temperature measurements.

3.1 Components
- Infrared Sensor: Located at the front of the device, used for non-contact temperature measurement.
- Dual Laser Pointers: Two laser dots indicate the measurement spot size.
- Display: Shows temperature readings, measurement units, battery status, and other indicators.
- Measurement Trigger: Activates the measurement and laser.
- Control Buttons: For navigating menus, adjusting settings (e.g., emissivity, units), and accessing functions like MIN/MAX.
- Battery Compartment: Located in the handle for battery installation.
4. Setup
4.1 Battery Installation
- Locate the battery compartment cover on the handle of the thermometer.
- Open the cover.
- Insert two AAA batteries, ensuring correct polarity (+/-). The device requires 2 AAA batteries, which are included.
- Close the battery compartment cover securely.
4.2 Initial Power-On and Unit Selection
Upon first use or after battery replacement, the device will power on. You may need to select your preferred temperature unit (Celsius or Fahrenheit).
- To change units: Typically, this involves pressing and holding a specific button (often the 'Mode' or 'Set' button, or an arrow button) while the device is off, then powering it on, or accessing a menu option. Refer to the on-screen prompts or the official Testo documentation for the exact procedure for your specific device firmware, as methods can vary.
5. Operating Instructions
5.1 Taking a Measurement
- Point the infrared sensor towards the target object.
- Press and hold the measurement trigger. The dual laser pointers will activate, indicating the measurement spot.
- The temperature reading will appear on the display.
- Release the trigger to hold the last measured value (HOLD function).

5.2 Understanding 12:1 Optics and Dual Laser
The 12:1 optics mean that at a distance of 12 inches, the measurement spot diameter is 1 inch. The dual laser pointers converge at the center of this measurement spot, helping you accurately identify the area being measured. This is particularly useful for measuring smaller objects or from a greater distance.
5.3 MIN/MAX Function
The device can display the minimum and maximum temperatures recorded during a continuous measurement. This function is useful for monitoring temperature fluctuations over a period.
- To activate MIN/MAX: Press the appropriate button (refer to your device's specific button layout, often an arrow or 'Mode' button) while taking a measurement. The display will cycle through current, minimum, and maximum values.
5.4 Emissivity Adjustment
Emissivity is a measure of an object's ability to emit infrared energy. Different materials have different emissivities. For accurate readings, adjust the emissivity setting on your thermometer to match the material being measured. Common emissivity values:
- 0.95 (default for many devices): Most organic materials, painted surfaces, water, plastic.
- 0.85-0.90: Concrete, brick, rough wood.
- 0.60-0.70: Polished metals (can vary significantly).
Consult an emissivity table for specific materials. Incorrect emissivity settings will lead to inaccurate temperature readings.
6. Maintenance
6.1 Cleaning
To ensure optimal performance and longevity, keep the device clean.
- Wipe the device exterior with a clean, damp cloth. Do not use abrasive cleaners or solvents.
- Carefully clean the infrared lens with a soft, lint-free cloth or a lens cleaning wipe. Avoid scratching the lens.
6.2 Battery Replacement
When the battery indicator on the display shows low power, replace the batteries promptly to avoid interruption of operation. Follow the battery installation steps in Section 4.1.
6.3 Storage
Store the thermometer in a dry, dust-free environment within the recommended temperature range (refer to specifications). If storing for extended periods, remove the batteries to prevent leakage.
7. Troubleshooting
If you encounter issues with your Testo 830-T1, refer to the following common problems and solutions:
- Device does not power on:
- Check if batteries are correctly inserted with proper polarity.
- Replace batteries with new ones.
- Inaccurate readings:
- Ensure the infrared lens is clean.
- Verify the emissivity setting matches the target material.
- Ensure the measurement distance is appropriate for the target size (12:1 optics).
- Avoid measuring through glass or highly reflective surfaces.
- Laser not visible:
- Check battery level.
- Ensure the measurement trigger is pressed.
If problems persist, contact Testo customer support for assistance.
