ETI 133-477 | Black Ball Probe | Type K, 2 m Stainless Steel Braided Lead
The ETI 133-477 is the black ball probe version supplied with a 2 m stainless steel braided lead. Its matt black, roughly 50 mm copper sphere absorbs radiant energy so the type K sensor reports the combined effect of air temperature and radiant heat. The lead uses glass fibre insulation with stainless steel over-braid and ends in a miniature type K connector.
Key features
- 2 m glass fibre insulated lead with stainless steel over-braid
- Miniature type K thermocouple connector
- Copper sphere about 50 mm in diameter, matt black outside
- Bright copper interior reduces internal radiation losses
- Robust build for industrial environments
