Product Description
HNAG920-VOC Portable PID VOC Gas Detector - Industrial Explosion-Proof VOC Monitor
The HNAG920-VOC is a professional portable single-gas VOC detector designed for industrial safety monitoring. It adopts advanced PID photoionization detection technology to accurately detect volatile organic compound concentrations in the air, with fast response, high sensitivity and strong stability. It is widely used in chemical plants, environmental monitoring, confined space operations, pharmaceutical industry, painting workshops and other scenarios for VOC leak detection and concentration monitoring.
High-Precision PID Detection with Wide Range Options
Advanced Photoionization Detection Principle
This VOC detector uses a high-performance PID sensor, which ionizes VOC gas molecules through ultraviolet light to generate current signals, and then calculates the gas concentration. It has high sensitivity to most volatile organic compounds, can detect low-concentration VOC leaks in time, and provides reliable safety guarantee for on-site operators.
Multiple Optional Detection Ranges
To meet the needs of different application scenarios, we provide a variety of VOC detection ranges for selection:
0-10ppm
0-50ppm
0-100ppm
0-200ppm
0-1000ppm
0-2000ppm
0-10000ppm
0-20000ppm
You can choose the appropriate range according to your actual detection needs, and we also support customized range services.
Humanized Design for Complex Working Environments
Auto-Rotating LCD Screen
The detector is equipped with a 2.0-inch high-definition color LCD screen, which supports 180° automatic rotation. No matter the operator holds it upright or upside down in a special working position, the screen content can be viewed normally, which greatly improves the operation convenience in complex environments such as confined spaces. The screen clearly displays real-time concentration, TWA/STEL values, temperature and humidity, battery level and other information at a glance.
Ergonomic Body & Convenient Charging
The body adopts an ergonomic anti-slip design, with a comfortable grip and easy one-handed operation. The side is equipped with a one-key alarm button, which can trigger an alarm in an emergency to remind surrounding personnel. It uses a Type-C charging interface, which is compatible with common mobile phone chargers and power banks, and the built-in large-capacity rechargeable battery supports long-time continuous work, which is very suitable for outdoor and field operations.
Multiple Communication Methods & Intelligent Data Management
This VOC monitor is equipped with rich data transmission functions to meet the needs of intelligent management:
4G / WiFi Wireless Transmission: Real-time upload of detection data to the cloud monitoring platform, supporting remote viewing and data storage by managers.
Bluetooth Connection: It can be connected to mobile phones via Bluetooth, and you can view real-time data, historical records and set instrument parameters through the matching APP.
LORA Long-Distance Transmission: Supports LORA wireless communication, which can realize long-distance data transmission in areas without mobile phone signals, suitable for large factories and remote operation sites.
Bluetooth Printing: It can be connected to a portable Bluetooth printer to print detection data and reports on site, which is convenient for work record filing.
The instrument has a built-in large-capacity data storage function, which can record historical detection data for a long time, supporting query and export, which is convenient for data analysis and safety management.
Industrial-Grade Explosion-Proof Design for Harsh Environments
ATEX & SIL2 Certified Explosion-Proof
The HNAG920-VOC gas detector has passed ATEX explosion-proof certification and SIL 2 safety level certification, with intrinsic safety explosion-proof design. It can be safely used in various explosive dangerous environments (Zone 1, Zone 2), meeting the safety standards of industrial sites.
Robust & Durable Body Structure
The shell is made of high-strength PC + TPU material, which is drop-resistant, wear-resistant, dust-proof and water-splash resistant, adapting to harsh industrial on-site environments.
It is equipped with multi-channel LED sound and light alarms and a buzzer. When the VOC concentration exceeds the limit, it will trigger high-decibel sound and bright light double alarms to ensure that operators can perceive the danger in time in noisy environments.
The back is designed with a sturdy back clip, which can be clipped on the pocket, belt or safety belt, freeing hands and facilitating operation.
Diffusion & Pump Suction Dual Sampling
The detector supports diffusion sampling and pump suction sampling. The top is equipped with a water trap filter to prevent water vapor and dust from entering the sensor and prolong the service life of the sensor. The pump suction sampling can realize long-distance sampling and detection in narrow spaces such as pipelines and deep wells.
Complete Set of Accessories for Portable Use
Each HNAG920-VOC VOC detector is equipped with a high-quality aluminum alloy carrying case, which is shock-proof and drop-resistant, making it easy to carry and store the instrument and accessories. The standard accessories include: instrument host, charging cable, user manual, calibration cover, water trap filter, etc.
Frequently Asked Questions (FAQ)
Q1: What is the service life of the PID sensor of the HNAG920-VOC detector?
A: Under normal use and regular maintenance, the service life of the PID sensor is about 2-3 years. The service life will be affected by the detection environment, gas concentration and frequency of use. We provide sensor replacement and calibration services to ensure the accuracy of the instrument.
Q2: Can this VOC detector detect all types of volatile organic compounds?
A: The PID sensor can detect most volatile organic compounds with ionization energy lower than the ultraviolet lamp energy (such as benzene, toluene, xylene, formaldehyde, TVOC, etc.). For specific gas types, you can contact us for confirmation, and we will provide targeted selection suggestions according to your detection needs.
Q3: Is the HNAG920-VOC detector suitable for confined space entry operations?
A: Yes, it is very suitable. The detector has ATEX explosion-proof certification, supports pump suction sampling for pre-detection before entering the confined space, and is equipped with an auto-rotating screen and sound-light alarm, which can provide reliable safety guarantee for confined space operations.
Q4: How often does the VOC gas detector need to be calibrated?
A: It is recommended to perform a calibration every 6-12 months under normal use. If the instrument is used in a harsh environment or frequently detects high-concentration gases, the calibration frequency should be appropriately increased. We provide professional calibration services and standard gas accessories.
Q5: Can the detection data of the instrument be exported to the computer?
A: Yes. The instrument supports a variety of data export methods: you can upload data to the cloud platform via 4G/WiFi for export, or connect to a mobile phone via Bluetooth to export data, and also support USB connection to a computer for data export, which meets the needs of different data management scenarios.
