ZHK2408 Dual-Path Volatile Organic Compounds (VOCs) Sampler

Main Features

● Display Touch Screen: The user interface resem-bles that of a mobile phone, making it easy to operate. 
● Digital Flow Rate Setting: Capable of digitally setting the sampling flow rate, featuring dual-path constant flow sampling. 
● Independent Sampling Gas Paths: Two sampling gas paths are completely indepen-dent: flow rates can be adjusted separately, allowing simultaneous sampling or sampling from only one path. 
● Closed-Loop Control: The flow rate is unaffected by voltage fluctuations and gas resistance changes, effectively addressing the challenges of constant low-flow sampling.

● Automatic Measurement: The instrument can automatically measure ambient temperature, atmospheric pressure, pre-sampling pressure, and sampling flow rate, and automatically convert to standard conditions volume. 
● Data Storage: Capable of automatically storing 100 sets of sampling data, including sampling date and time, ambient temperature, atmospheric pressure, standard volume, adsorption tube number, and sampling flow rate. 
● Data Export: Stored data can be exported using a data cable; the interface is a common mobile phone type.Overload Protection: If the sampling flow rate deviates from the set flow rate by more than ±10% and this condition lasts for 60 seconds, the sampler will stop operating, display the fault reason, and retain the sampling data. 
● Low Battery Alert: When battery power drops below 10%, the instrument will alert the user to charge while in the powered-on state. 
● One-Button Lock Screen Function: The one-button lock screen feature locks the functions to prevent accidental operation. 
● Automatic Leak Detection: The instrument can automatically check the gas path for leaks.

● Built-In Lithium Battery: Can be charged using common tools such as portable power banks or mobile phone power adapters.
