Functional features:
-
Multi-functional device, allowing for flexible combinations of medium-flow sampling, low-flow heating, low-flow constant temperature, and micro-flow sampling methods, with independent control and flexible configuration.
-
Features a 7.0-inch wide-temperature, high-brightness color touch screen display, clearly visible in sunlight, with a beautiful interface and convenient operation.
-
Dual operation modes (button and touch) to suit various user preferences.
-
Optional built-in rechargeable lithium battery, providing over 4 hours of operation on a single charge.
-
Massive data storage capacity, storing over 100,000 sets of data.
-
Particulate matter sampling flow rate (10~130) L/min is adjustable; with corresponding sampling heads, it can be used for sampling fluorides, heavy metals, SVOCs, etc.
-
Uses an imported sampling pump with high load capacity, low noise, stable flow rate, and long service life.
-
Automatically measures pre-meter temperature and pressure, and automatically calculates the standard volume of sampled air.
-
Small size and lightweight, making it easy to carry.
-
Automatic data protection in case of power failure during sampling; sampling resumes after power is restored.
-
Dual data output modes: data can be printed via Bluetooth or exported to a USB drive.
-
Aluminum alloy sampling head, resistant to electrostatic adsorption.
-
The entire device features excellent dustproof and waterproof design, ensuring normal operation in rainy and snowy weather.
-
The entire device is designed with electromagnetic compatibility in mind, possessing strong anti-interference and anti-radiation capabilities.
