1.Specifications / structure
1). Material: made of stainless steel by stretching forming, attractive appearance, no rust,
2). Bearing: wholel sealing bearing, which can ensure it operates smoothly and constantly.
3). Special central shaft design, high-class lubricating bearing system: preventing turbine blades
Rotating at high speed from deformation, and extending the service life.
4). Inside support frame: cast iron.

2.Advantages
1). Automatically running. Wind drive. One time investment, no anymore cost.
2). No operating cost, no electricity consumption, environmental protection, energy-saving.

7. Why should you consider a no power roof turbine ventilators?
The ventilator is very quiet and the rotating action provides employees with visual knowledge that the unit is operating.

The fire control used in the industry, civil building and people¡¡¥s air defense project mainly arranges cigarettes, can be used and ventilated and taken a breath in the room at ordinary times. The electrical machinery adopts the high temperature type, and cool the wind circulatory system, can run for a long time under 100 degrees centigrade of medium gas , can send exhaust gas of 280 degrees centigrade and up to 40 more than of kind steadily . Three kinds of types, such as horizontal, roof type, cupboard type, etc. Are suitable for selecting for use. Arrange cigarette ventilate two time spent, can select pairs of speed electrical machinery for use , ventilate and take a breath at a low speed, arrange cigarettes at a high speed.

Cooling capacity from 400kW to 3100kW,cooling water input temperature 7íµú¼ output water temperature 12íµ.

Soil NPK Sensor
The soil nitrogen, phosphorus, and potassium three-in-one fertility sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and determining the fertility of the soil by detecting the content of nitrogen, phosphorus, and potassium in the soil, thereby facilitating the systematic assessment of the soil condition. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
FEATURES:
1) Low threshold, few steps, fast measurement, no reagents required, unlimited detection times.
2) High measurement accuracy, fast response speed and good interchangeability.
3) The electrode is made of a specially treated alloy material, which can withstand strong external force and is not easy to be damaged.
4) Completely sealed, resistant to acid and alkali corrosion, can be buried in the soil for long-term dynamic testing.
5) Probe insertion design ensures accurate measurement and reliable performance.
Electrical Wiring
�.Instructions
1.1 Quick test method
Select a suitable measurement location, avoid stones, and ensure that the steel needle does not touch hard objects. Discard the topsoil according to the required measurement depth, and maintain the original tightness of the soil below. Hold the sensor vertically and insert it into the soil. It is not allowed to shake left and right, it is recommended to measure multiple times to find the average value within a small range of one measurement point.
1.2 Buried survey
Vertically dig a pit with a diameter of> 20cm, insert the sensor steel needle horizontally into the pit wall at a predetermined depth, bury the pit tightly, and stabilize it for a period of time, then you can perform continuous measurement for several days, months, or even longer.
1.3 Precautions
1). All steel needles must be inserted into the soil during measurement.
2). Avoid direct sunlight on the sensor, which will cause excessive temperature. Pay attention to lightning protection in the field.
3). Do not bend the steel needle violently, do not pull the sensor lead wire with force, and do not beat or violently hit the sensor.
4). The protection grade of the sensor is IP68, which can soak the sensor in water.
5). Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long time.
Application
The sensor is widely used in soil nitrogen, phosphorus, potassium detection, precision agriculture, forestry, soil research, geological exploration, plant cultivation and other fields.
