NP-500V型微粒計數(shù)系統(tǒng)
|
| |
最適宜用于水質(zhì)純化的激光液體粒度計數(shù)和高靈敏度的濁度計，其適合于衛(wèi)生和勞動福利部臨時政策。非常有用的連續(xù)控制濾池的工具(采用在線式型號)。
|
 |
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. |
應(yīng)用領(lǐng)域：
|
|
產(chǎn)品特點：
|
 |
同時進行微粒計數(shù)和濁度測量，其適合于衛(wèi)生和勞動福利部臨時政策 |
|
|
照亮測量區(qū)域，無微粒漏檢 |
|
|
在相同直徑范圍內(nèi)，能區(qū)分霉菌(Chyptosporidium)和鞭毛蟲卵(giardia)，數(shù)據(jù)可以快速得到評估 |
|
|
具有氣泡去除槽，除去空氣氣泡，以防止測定錯誤 |
|
|
光源采用長壽命的半導(dǎo)體激光器 |
|
|
具有RS-232C和4-20mA(4道)的標準信號輸出 |
|
|
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. |
