HX-301 VOCs Sampler

product description

This instrument uses passive sampling method to collect various gases. Mainly composed of sampling tubes, vacuum boxes, and gas samplers, the exhaust gas emitted from the fixed pollution source exhaust pipe is directly collected and stored in a chemically inert fluoropolymer film airbag.

Execution standards

HJ 732-2014 Sampling Bag Method for Volatile Organic Compounds in Fixed Source Exhaust Gas

HJ 38-2017 "Determination of Total Hydrocarbons, Methane, and Non Methane Total Hydrocarbons in Waste from Fixed Pollution Sources by Gas Chromatography Method"

Product Features

Sampling tube

Made of titanium alloy material and lined with PTFE exhaust pipe, the sample gas does not come into contact with any metal

The front end of the sampling tube is equipped with a detachable filled quartz cotton PTFE filter

Aluminum alloy handle with built-in temperature controller, can be operated by connecting the power supply

The sampling tube is heated throughout the entire process, and the heating temperature is continuously adjustable

The sampling tube has a total length of 1.2 meters and is made of PTFE with an inner diameter of 4mm

Configure a 1.7-meter PTFE lined insulation pipe

vacuum box

Made of PP impact resistant material, sturdy and durable, with strong compressive strength

Applicable airbags: medium vacuum box (1-3) L, large vacuum box (3-8) L

SAMPLER

The shell is made of ABS engineering plastic, which has high strength and good impact resistance

Built in high-performance lithium battery for ultra long battery life

Built in high negative pressure vacuum pump, sampling and cleaning can be achieved by switching the button

Equipped with airtightness detection function (when the system negative pressure is not less than 13kPa, the pressure drop within 1 minute shall not exceed 0.15kPa)

The suction flow adjustment knob can achieve fast and slow sampling
