二、Requirements of size :seeing the drawing.
三、Packing and depositing.
(a). The product must packing before leaving plant so that avoid attaint during transport ;and reach the dust-proof requirement , meet the transport requirements of landway and water way, And the inspection report of product put in the case.
(b).The mark of product package must clear and trim .The product should be deposited in the medium with excellent ventilation and with no causticity ,and the relative humidity less than 90％(20±5℃).
The product don′t use in the environment with fire.
Operating according to acquirer′s acceptance understand.
Note: 1.You must notice the total length and depth of penetration of protecting tube when you make order, and the depth of penetration must more than 10 times of diameter of protecting tube.
2.The temperature transmitter must note temperature range that corresponding with output signal ;The length from installation fixing device to junction box not less than 100mm when the span of temperature transmitter reaches more than
100℃,and not less than 250mm when the span of temperature transmitter reaches more than 200℃.
