◆ Positive displacement brushless vane pump, load capacity greater than 35kPa, low noise and long service life

◆ Meet three sampling flow rates of 16.7L/min, 50L/min and 100L/min

◆ Collect inhalable particulate matter, fluoride, heavy metals, SVOCs in ambient air

◆ Adopt wide temperature display screen, Chinese menu display, pictures and texts, easy to operate

◆ With multiple sampling, sampling every other day, cycle sampling and other sampling methods

◆ Adopt imported digital flow sensor to control the sampling flow according to the set value constant current sampling, automatically measure temperature, atmospheric pressure, pre-meter temperature, pre-meter pressure and other parameters, and display the sampling volume

◆ It has the function of gas circuit blockage and low flow protection. If the set flow rate is not reached within a certain period of time during sampling, the instrument will enter the automatic protection mode.

◆On-line calibration of the parameters of the instrument is carried out directly through the keyboard, and the maintenance and calibration of the instrument have the function of authority management to ensure the safety of the parameters of the instrument

◆ With a real-time clock, the sampling data is automatically memorized, and it will be used first when the machine is turned on next time, enabling one-key sampling

◆ Automatically store monitoring data, and can copy and print external printer or USB disk

◆ The cutter is made of aluminum alloy and has been oxidized to resist electrostatic adsorption.

◆ The fluoride sampling head can be placed with a 90mm filter membrane (effective diameter of 80mm), equipped with two layers of stainless steel supporting filter membrane mesh pads, and the two layers of mesh pads are separated by a 2mm~3mm spacer

◆ Standard SVOCs sampling tank for SVOCs sampling

◆It adopts waterproof structure design, which can prevent rain and snow from attacking when working in the field
