WARNINGS
To ensure safe operation and service, follow these instructions
- Read the instructions to ensure safe operation.
- Always wear approved eye protection.
- Do not use if the housing is damaged in any way.
- DO NOT use if the Lightning connector/adapter is damaged in any way.
- There are no user-serviceable parts inside. DO NOT open or attempt to repair.
NOTE: Do not point the camera at the sun or any other strong energy source. This can affect the accuracy of the camera or cause damage to the sensor
CAUTION
- Burn Hazard. Reflective materials may have a higher actual temperature
than the measured temperature. Set emissivity to match the object being measured (see Emissivity section).

EMISSIVITY
Emissivity is a measure of the ability of a surface to emit thermal energy by radiation. Different types of surfaces (metals, masonry, wood, etc.) emit thermal energy through radiation at different efficiencies. Accordingly, these materials have different emissivity coefficients which must be considered in order to make accurate measurements with an infrared thermometer.
Emissivity on the TI222 may be adjusted from 0.01 to 0.99 to enable accurate measurement of the temperature of most types of materials. Generally speaking, shiny bright surfaces such as chrome, white boards, etc. exhibit lower emissivity than flat black materials.
For guidance only, the chart on the next page may be used to estimate emissivity for many different types of materials. However, the emissivity of surfaces is dependent upon many parameters such as surface finish, temperature, shape of the object, etc.
This chart should be used for guidance only.
| Material | Emissivity |
| Asphalt | 0.93 |
| Red brick | 0.93 |
| Gray brick | 0.75 |
| Porcelain ceramic | 0.92 |
| Fired clay | 0.91 |
| Rough concrete | 0.94 |
| Cotton cloth | 0.77 |
| Smooth glass | 0.92 – 0.94 |
| Granite | 0.45 |
| Gravel | 0.28 |
| Smooth ice | 0.97 |
| Smooth white marble | 0.56 |
| Black paint | 0.96 |
| Hard rubber | 0.94 |
| Wood | 0.80 – 0.90 |
| Matte copper | 0.22 |
| Commercial sheet aluminum | 0.09 |
| Cold rolled steel | 0.75 – 0.85 |
