　　沥青蒸发损失试验箱是**沥青检测仪器，适用于测定石油沥青材料的蒸发损失，蒸发损失后的残留物应进行针入度试验，计算残留物针入度占原试样针入度的百分率使用前务必仔细阅读说明书。

　　Asphalt evaporation loss test box is a testing instrument for asphalt,suitable for measuring the evaporation loss of petroleum asphalt materials.The residue after evaporation loss should be tested for penetration,and the percentage of penetration of residue to the penetration of the original sample should be calculated.Be sure to read the instructions carefully before use.

　　沥青蒸发损失试验箱特点：

　　用于测定石油沥青材料的蒸发损失，蒸发损失后的残留物应进行针入度试验，计算残留物针入度占原试样针入度的百分率，并根据需要测定沥青残留物的延度、软化点等其它试验，以评定沥青受热时性质的变化。

　　仪器为不锈钢内胆、触摸式开关，在50～199℃温度范围内可任意设定、显示设定和即时温度，设定后烘箱由自动控制系统恒温。

　　Features of asphalt evaporation loss test box:

　　It is used to measure the evaporation loss of petroleum asphalt materials.The residue after evaporation loss should be tested for penetration,calculate the percentage of penetration of the residue in the penetration of the original sample,and measure the ductility of the asphalt residue as required.Other tests,such as the softening point,are used to evaluate changes in the properties of the asphalt when heated.

　　The instrument is a stainless steel liner and a touch switch.It can be set arbitrarily within the temperature range of 50～199℃,display settings and instant temperature.After setting,the oven is thermostated by an automatic control system.
