The OM3500 handheld total hydrocarbon analyzer is a compact and lightweight VOCs analyzer designed based on the FID principle. Its small size and light weight make it easy to carry and use, with a user-friendly touchscreen interface for simplified operation.

01 Product features:

Secure and convenient:

The entire machine adopts flameproof design and intrinsically safe design.

The 20L replaceable solid-state low-pressure hydrogen storage alloy cylinder ensures enhanced safety and convenience.

The hydrogen generator operates on electrolysis of water, enabling worry-free hydrogen production without the need for traditional hydrogen tank refilling.

A 3.5-inch touchscreen with just 2 steps for detection.

The instrument’s built-in screen is used for data viewing, calibration, and setting functions.

The host has 4GB of storage space for worry-free storage.

Data accuracy:

The FID detector, which operates on the same principle as online VOCs, offers broader detection gas range and higher accuracy than handheld PID.

The micro EPC maintains constant current to regulate hydrogen flow rate, ensuring stable FID combustion with minimal flameout risk.

The FID’s independent chamber anti-interference design ensures accurate measurement data.

Smart reminder:

Proactive alert features: battery life, excessive leakage, airway abnormalities, consumable replacement, and maintenance reminders.

high reliability ：

Dual ignition system with automatic ignition upon flameout detection, ensuring stable ignition in low-temperature environments.

Automatic purging of gas lines during startup/shutdown to extend equipment lifespan.

Large-capacity battery with a runtime of ≥8 hours at room temperature.

The plug-in hydrogen storage alloy carrier gas cylinder has a endurance time of at least 12 hours at room temperature.

Other features:

Dual-mode communication with built-in Bluetooth and Wi-Fi modules.

Large-capacity storage supports unified data export via USB.

The optional camera module can record photos or videos throughout the process.

The auxiliary lighting function facilitates nighttime detection.
