Explosion proof radiation thermometer IR-CD
The IR-CD series is a pressure explosion proof radiation thermometer capable of measuring temperatures even in environments where flammable gases or liquid vapors are present and there is a risk of explosion.
It is certified as Ex db ⅡB T5 Gb by the Technology Association of Industrial Safety in Japan.
The lineup includes measurement temperature ranges of:
- 80 to 800°C (low to medium temperatures)
- 200 to 2000°C (medium temperatures)
- 500 to 3500°C (high temperatures).
Despite its explosion proof construction, it is compact and light-weight, and when combined with a sealing window, the measurement window becomes easier to clean.
