Model: HNAG1000-O3
Detection: O3 (Ozone)
Detection Principle: Electrochemistry
Detection range: 0-10PPM / 0-100PPM / 0-1000PPM
The HNAG1000-O3 online gas concentration detector is engineered for the real-time and highly accurate continuous detection of Ozone (O3) gas concentrations and potential leakages across various industrial environments. By utilizing advanced electrochemistry detection principles and robust microcontroller technology, this analyzer delivers rapid response times (T90 < 10S) and exceptional measurement precision (±2% F.S), ensuring reliable stability and repeatability.

Safety is paramount in hazardous locations. This fixed O3 detector features an intrinsically safe circuit design housed within a rugged enclosure that achieves an Ex d IIC T6 explosion-proof rating. It is equipped with secondary lightning protection and anti-static capabilities that exceed national standards, allowing it to withstand high-intensity pulse surge current impacts. Furthermore, the device boasts an IP66 protection grade, effectively guarding against industrial dust, splashing water, and short periods of rain.


To seamlessly integrate with modern industrial control systems, the detector simultaneously outputs a standard 12-bit precision 4-20mA signal and an RS485 signal using the standard MODBUS RTU protocol, both supporting transmission distances up to 1Km. It also includes one set of passive contact relays (capacity 220VAC 3A / 24VDC 3A) to directly drive external high-power equipment such as solenoid valves or exhaust fans.
For comprehensive remote monitoring, the device can be customized with various wireless transmission modules, including GPRS, 4G, WIFI, LORA, and ZigBee. This allows real-time gas data to be uploaded directly to cloud platforms, mobile phones, or environmental protection bureaus without distance restrictions.

The detector is equipped with a 2.5-inch high-definition color screen (TF) that vividly displays real-time gas concentration, ambient temperature, and humidity. To maintain safety protocols in explosive zones, operators can utilize the included standard infrared remote control to perform multi-level calibrations, zero-point adjustments, and configure alarm settings safely without opening the device cover.


Q1: What are the available measurement ranges for this ozone detector?
A: The HNAG1000-O3 model offers customizable measurement ranges of 0-10PPM, 0-100PPM, or 0-1000PPM, providing resolutions of 0.1PPM or 1PPM to suit specific application requirements.
Q2: What is the operating temperature and humidity range?
A: The device operates reliably in temperatures ranging from -20℃ to 50℃ and can handle humidity levels from 0 to 95% RH.
Q3: How does the local alarm system function?
A: The detector is equipped with a built-in on-site sound and light alarm. It comes standard with a two-level alarm configuration (three-level is optional), allowing users to set specific high, low, or interval control alarm modes.
Q4: Does the sensor require frequent manual calibration for zero drift?
A: No, the system automatically tracks the zero point to prevent drift over time. It also features built-in temperature compensation to maintain high accuracy and stability across fluctuating environmental conditions.
Q5: Can this detector be installed outdoors?
A: Yes, it has an IP66 rating protecting it from splashing water. However, if installed outdoors, it is highly recommended to install a rain shield above the detector, and the probe should always be installed facing downwards.
