Model: HNAG900-VOC
Detection: VOC (Volatile Organic Compounds)
Detection Principle: Electrochemistry / PID
Detection range: 0-2000PPM(Customizable)
The HNAG900-VOC portable pump suction VOC gas concentration detector is designed for real-time, highly accurate detection of organic vapor concentrations and leakages across demanding industrial environments. Built with an IP65 protection grade and Ex ib II CT4 Gb explosion-proof certification, it ensures exceptional reliability in hazardous locations.

Equipped with a 32-bit microprocessor and high-speed processing circuitry, this portable gas leak detector delivers rapid measurements with a response time of T90<10S and sampling accuracy of ±3%F.S. The system incorporates high-precision electrochemical or Photoionization Detection (PID) principles for accurate volatile organic compound tracking.


The instrument features a built-in micro vacuum sampling pump with adjustable pump speeds to suit different sampling distances. A flexible metal probe with double-layer wire spring protection allows safe and precise gas sampling in narrow pipe crevices or deep container openings.

Measurement data is clearly displayed on a 3.5-inch TFT color screen (480*320 resolution). Operators can easily view real-time concentration curves, set custom logging intervals, and toggle between Chinese and English displays.
Massive Log Storage: Stores up to 100,000 data logs and 1,000 alarm entries.
USB Data Export: Features an external USB port for downloading and analyzing historical concentration trends on a PC.


Powered by a high-capacity 5400mAh rechargeable lithium battery, the device offers long operational hours for on-site inspections. It supports optional LORA, 4G, or 5G wireless transmission modes to upload real-time readings to cloud platforms or central gateways. Each kit comes packaged in a heavy-duty aluminum carrying case for safe transport.


Q1: How long is the sensor lifespan of this portable VOC detector?
A1:Under normal working conditions, the effective lifespan of the VOC sensor is 1 to 3 years. Regular calibration checks every 6 to 12 months are recommended to maintain optimal precision.
Q2: How does the pump suction function assist in remote VOC leak detection?
A2:The detector features a built-in micro vacuum suction pump with adjustable speed control. Paired with the double-layer spring-protected flexible metal probe, it allows operators to draw air samples safely from confined spaces, deep tanks, or narrow pipe joints.
Q3: What safety mechanisms are implemented for over-range gas concentrations?
A3:The detector features configurable standard two-level (high and low) sound-and-light alarm thresholds. During daily operation, avoid exposing the sensor to gas concentrations beyond its maximum measurement range to prevent sensor damage.
Q4: Does the device support real-time data curve viewing on-site?
A4: Yes. The 3.5-inch TFT color screen displays real-time concentration values along with historical trend curves, enabling field engineers to visualize VOC concentration fluctuations instantly without needing a computer.
Q5: Can the device operate in high-humidity or high-temperature environments?
A5: The standard operating range is -20 to 50°C and 0-95%RH (non-condensing). For extreme temperatures or high humidity, an optional high-temperature sampling handle or preliminary dehumidification filter must be used before sampling to protect the sensors.
Q6: What happens when the battery runs low during long-term field testing?
A6: Powered by a 5400mAh battery, the device provides extended operation. If the battery drops to 0%, a countdown auto-shutdown screen appears. If forced on, it will automatically shut down after 5 minutes to prevent battery over-discharge and protect system data.
