Product introduction
The GR-1350D environmental air comprehensive sampler (hereinafter referred to as the sampler) isused to collect various harmful gases in ambient air and indoor air using the solution absorptionmethod; it also uses the filter membrane weighing method to collect total suspended particulates(TSP), inhalable particulates (PM10) or (PM2.5), fluorides, heavy metals, SVoCs, etc., in ambient air.lt can be used by environmental protection, health, labor, safety supervision, military, scientific
research, and education departments for routine and emergency monitoring of gaseous substancesand aerosols.

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.
