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.

Frequently Asked Questions (FAQ) for HZ-HA-270P

Why choose 270P camera

Can I replace or swap the battery of the HZ-HA-270P/170P in the field?

No. To comply with strict ATEX intrinsically safe standards (Ex ib IIIC $T80^{\circ}CDb$ and Ex ib IIC T4 Gb), the HZ-HA-270P/170P is engineered with a sealed, non-replaceable battery. It provides up to 4 hours of continuous operating time. For safety compliance, charging must be performed entirely outside of designated hazardous zones using the Type-C direct charging port.

How does the thermal imaging feature work alongside the acoustic detection?

The HZ-HA-270P integrates a high-resolution

640^{*}512

thermal sensor

with a 138-channel low-noise MEMS microphone array

. This dual-modal design allows inspectors to simultaneously identify ultrasonic anomalies (such as partial discharge or pressurized gas leaks)

and temperature anomalies ranging from

-20^{\circ}C\sim550^{\circ}C

on the same 5-inch capacitive touch screen

What is the minimum gas leak rate the camera can detect in an industrial environment?

The HZ-HA-270P/170P features highly sensitive acoustic capabilities, allowing it to detect minute gas leaks as low as >0.0032L/min from a distance of 2.5 meters

. The system's overall operating distance spans from 0.3 meters up to 200 meters

, ensuring safe inspections in complex or hard-to-reach industrial areas.

Do I need to export data to a PC to identify the type of partial discharge?

No, external software is not required for immediate diagnostics. Driven by a built-in AI engine

, the camera supports real-time partial discharge type intelligent analysis directly on the device

. It automatically predicts and classifies discharge issues into Corona, Floating, Surface, or Noise categories

Is the camera suitable for detecting mechanical faults like bearing wear?

Yes, the HZ-HA-270P supports mechanical fault detection

in addition to gas leaks and partial discharge. It captures the high-frequency friction noise generated by failing bearings or unbalanced rotors across its 2kHz to 100kHz frequency bandwidth
