COH-400型石油产品色差计
|
| |
紧凑型设计，重量轻，电池供电和操作简单。主要用于豆酱和粉末的颜色差异管理等等。 |
 |
|
Using this COH 400,it is
possible to measure transmitted color and haze
(turbidity) of resin, glass and liquid samples, as
well as total light transmittance, diffuse
transmittance, parallel transmittance, Saybolt
color, ASTM color, Hazen color number (APHA) and
Gardner color. |
应用领域：
|
|
产品特点：
|
 |
该型满足豆酱工业测量项目的要求，具有接受/拒绝测定和平均功能 |
|
|
无预热时间要求，即开即用，单键操作设置色差参比值，平均测量值和储存数据 |
|
|
采用传感器检测外界温度的变化，并显示报警信息，具有自动节电功能设计 |
|
|
可选择数据接收/编辑Windows兼容软件和打印机(选择件) |
|
|
You can enjoy a large bright fluorescent character display, with easy screen visibility from any angle. |
|
|
Connection with PC is possible with RS-232C interface equipped as a standard configuration. |
|
|
Various modes of measurement values can be printed out directly, thanks to its built-in printer with very little printing noise. |
|
|
Using this one unit, it is possible to make general color measurements, petroleum product color measurements (Saybolt color, ASTM color, Harzen color number (APHA) and Gardner color) and haze (turbidity) measurements. |
|
|
Measurements using a test tube are also possible in option. |
