NP-500V型微粒计数系统
|
| |
最适宜用于水质纯化的激光液体粒度计数和高灵敏度的浊度计，其适合于卫生和劳动福利部临时政策。非常有用的连续控制滤池的工具(采用在线式型号)。
|
 |
This is also highly sensitive
laser particle counter (turbidimeter) for clean
water, most suitable as the counter measurement
against the provisional guide line for clean water
by Ministry of Health, Labor and Welfare. It is used
as an on-line system, and has a strong effect on the
maintenance and management for a filter basin.
Turbidimeter used exclusively for low
turbidity measurement based on the particle counting
method. |
应用领域：
|
|
产品特点：
|
 |
同时进行微粒计数和浊度测量，其适合于卫生和劳动福利部临时政策 |
|
|
照亮测量区域，无微粒漏检 |
|
|
在相同直径范围内，能区分霉菌(Chyptosporidium)和鞭毛虫卵(giardia)，数据可以快速得到评估 |
|
|
具有气泡去除槽，除去空气气泡，以防止测定错误 |
|
|
光源采用长寿命的半导体激光器 |
|
|
具有RS-232C和4-20mA(4道)的标准信号输出 |
|
|
Both particle counts and turbidity can be measured simultaneously. |
|
|
Cryptsporidium and giardia are sorted to be the same particle size, so variation in particle size can be judged easily at a glance. |
|
|
Deforming bath is equipped with this model for the protection from measuring error caused by air bubble. |
|
|
A long life semi-conductor laser is used as a light source. |
|
|
Data analysis and filing software will be available in option. |
|
|
Contamination detector is equipped with this model. |
