useLawn samplerBefore, the first step should be to remove stones, large roots of plants, etc., mix them thoroughly and lay them in a square shape, divide the diagonal into four parts, take two parts of the diagonal, and discard the other two parts. If there are still many samples obtained, they can be repeated, and thenLawn samplerThe collected sample should be controlled at around 1 kilogram. Sample bags can be made of clean and sturdy plastic bags. At the same time, fill out the survey form and place the label in the soil. If the lawn is very wet, also place a label on the outside, which can be written on a plastic bag with a marker pen.

Lawn samplerAdopting integrated stretching, the inner liner is smooth and easy to clean, with strong corrosion resistance, avoiding welding scars caused by welding the inner liner in the past. Long term use can lead to water leakage and rust. Compared to the previous flat design, we adopt a sloping design for the instrument, which is convenient for customers to set and read. It is made of food grade silicone, which is different from the previous aluminum cover. A diversion valve is added to the air circuit, which makes the flow more stable. The flow range is (0.1-1.2) L/min. We use orifice plate flow control and imported pressure difference sensor, which has high accuracy; If the sampling flow rate does not reach 90% of the set flow rate within 30 seconds, the instrument will automatically shut down for protection.
