ATEX-Certified Dual-Modal Diagnostics
The HZ-HA-270P integrates acoustic and thermal imaging technologies into a single, intrinsically safe platform. It meets stringent ATEX explosion-proof standards, certified for Ex ib IIIC $T80^{\circ}CDb$ and Ex ib IIC T4 Gb. This compliance ensures that maintenance professionals can conduct non-contact inspections of critical infrastructure in highly explosive oil, gas, and chemical environments without introducing electrical ignition risks.

Advanced Acoustic Array & AI Analytics
Equipped with 138 low-noise MEMS microphones , the system operates across a 2kHz to 100kHz frequency bandwidth to capture subtle ultrasonic anomalies. Driven by Hertzinno's AI engine, the system offers intuitive operation and real-time partial discharge type intelligent analysis, accurately classifying Corona, Floating, Surface, and Noise discharge types. Furthermore, it provides accurate estimations of gas leak rates and associated costs, detecting leakages as small as >0.0032L/min from a 2.5-meter distance.

High-Resolution Thermal Imaging
Complementing the acoustic capabilities is a built-in uncooled microbolometer thermal sensor with a $640^{*}512$ resolution and a 30Hz frame rate. It measures temperatures ranging from $-20^{\circ}C\sim550^{\circ}C$ with an exceptional NETD of ≤40mk. This thermal imaging function allows engineers to cross-verify mechanical friction, electrical overheating, and gas leaks simultaneously on the same screen.

Lightweight & Ergonomic Operation
Designed as the world's lightest acoustic camera, the HZ-HA-270P significantly reduces operator fatigue during extensive field patrols. The device features a 5-inch capacitive touch screen with a 720P display. Supported by a 4-hour battery operating time, Type-C direct charging, and an IP54 protection level, it ensures reliable and efficient inspection workflows in demanding industrial scenarios.
