Kirisun PT7200EX Explosion‑Proof Two‑Way Radio | ATEX Intrinsically Safe Walkie Talkie
The Kirisun PT7200EX is a professional explosion‑proof two‑way radio with ATEX certification, engineered for safe and reliable communication in hazardous areas such as oil & gas, chemical industries, and mining operations.
Main features
Purpose-Built Safety
CQST Ex ia IIC T4 Ga certification confirms this explosion proof walkie talkie is approved for Zone 1 & Zone 2 explosive atmospheres.
Integrators can specify a single kirisun walkie talkie across oil, gas, chemical and grain-dust projects without worrying about regional safety deviations.
Loud & Clear in Noise
1 W audio amplifier + 1000 mW front-firing speaker deliver >95 dB SPL at 30 cm; no extra remote-speaker mic required in most plants.
All-Day Power, Hot-Swap Safe
1700 mAh Ni-MH KIRISUN KB-70A-Ex battery yields 12–14 h duty cycle; battery latch allows swap outside the Ex zone in <15 s.
Compact, Wearable Form Factor
320 g with battery, 113 × 54 × 34 mm—fits under arc-flash suits and inside chemical splash hoods, increasing user compliance.
