Do you know what to prepare before using the drying oven? 1. The box is placed on the dry floor and work surface in the room without using other fixtures. 2. A knives or air switch should be installed in the power supply line for the purpose of this box, and use a wire that is twice as thick as the cross-sectional area of ​​the power line as the grounding line. 3. Before powering on, check the electrical performance of the box first, and pay attention to whether there is open circuit or leakage. 4. When everything is ready, put in the test sample, close the door, and open the exhaust valve if necessary. The gap is about 10mm. 5. Separate water incubator, connect distilled water or deionized water into the water inlet, and add water overflow. Use after power on: 6. After connecting the power supply, the heating switch can be turned on, and the drying box will set the working temperature value required by the temperature setting dial. The constant temperature incubator and the water-proof incubator place the temperature “set-measure†switch to “setâ€. After adjusting the required operating temperature of the temperature setting knob, set the “set-measure†switch to “measureâ€. At this point, the temperature inside the box starts to rise, and the green light is on (intelligent or special requirements, attached to the manual). 7. When the temperature rises to the required working temperature, the green light is turned off, and then the green light is re-brightened. When the indicator light is alternately turned off, it is the constant temperature point. At this time, the knob can be fine-tuned and the green light is extinguished to keep it constant. It is very likely that the temperature will continue to rise at constant temperature, which is the effect of residual heat, which will be stable in about half an hour. When the temperature in the working chamber is stable (the so-called "constant temperature state"), the temperature controller can be slightly adjusted to improve the accuracy of the temperature control. Any operating temperature can be selected by this method. 8. When the drying box is at constant temperature, the high temperature switch should be turned off, leaving only one set of electric heaters to work, so as to avoid excessive power and affect the constant temperature accuracy. When the working temperature is less than 150 °C, only one set of heaters should work, and the high temperature switch should be turned off. 9. After the temperature is reached, it can be kept constant for a certain period of time according to the test requirements (W type can set the constant temperature working time). In this process, the temperature controller can automatically control the temperature without adding manual management. Shanghai Sujing Industrial Co., Ltd. Rainwear is
raincoat or rainsuit which is a waterproof or water-resistant coat worn
to protect the body from rain. The term rain jacket is sometimes used to
refer to raincoats that are waist length. A rain jacket may be combined
with a pair of rain pants to make a rain suit. Raincoat,Yellow Rain Coat,Nylon Rain Coat,Nylon Rain Suit Greateagle Safety Products Co., Ltd. , https://www.greateaglesafety.com

Modern
raincoats are often constructed of breathable, waterproof fabrics such
as Gore-Tex or Tyvek and coated nylons. These fabrics allow some air to
pass through, allowing the garment to 'breathe' so that sweat vapour can
escape. The amount of pouring rain a raincoat can handle is sometimes
measured in the unit millimeters, water gauge.
