详细说明

    
        
            COD-35K便携式COD分析仪         
        
            COD-35K是利用密封催化消解,然后进行比色法测量,即在强酸性溶液中加入一定量的包含重铬酸钾在内的专用氧化剂,并在专用催化剂的作用下于165℃恒温消解水样10分钟,使得重铬酸钾中的六价铬被水样中有机物还原为三价铬,在波长610mm处测定三价铬的含量,进而换算为COD的浓度。         
        
            技术参数:
1. 测量范围: 52000mg/L,超过2000mg/L可稀释测定                    
2.
仪器误差:误差
≤±5%
3.
仪器重复性:
≤3%        
4.
抗氯干扰:
≤1200mg/L
5.
单色波长:
610nm         
6.
消解温度:165
±1.5
7. 消解时间:10分钟
         
8.
批处理量:12个水样/
  
9.
最大功耗:
300W
10.
外形尺寸:主  机:168mm×228mm×75mm(长××高)
    
消解器:130mm×120mm×95mm(长××高)

11.重量:总净重小于3kg         
        
            产品配置清单:
主机1 (含消解器)、电源线2根、电缆线1根、反应管12支、比色皿2个、专用试剂1套(可测定500个样品),防护罩1个、使用说明书1份、产品合格证1份及保修卡1份。         
        
            产品主要特点:
1 利用冷光、单色光作光源,光学稳定性极佳,不会受到各种光的干扰。
2 利用PID自动控制消解温度,温控精度高。
3 双行液晶显示,操作简便。
4 高温消解和比色(含主机)两部分分离,使得温度对光学部分影响达到最小。
5 一次可消解12个水样,每批水样测定时间仅20分钟左右。
6 内存255个带时间标签的测量数据。
7 数据断电不会丢失。
