Product Detail

Brief Introduction

This automatic water sampler is widely used in the pollution sources, sewage treatment plants, which is used with COD, ammonia nitrogen, heavy metal etc.

Online monitors for continous water sampling. Apart from traditional sampling models such as timing, timing equal ratio, flow equal ratio, 

it even has synchronous sampling, excessive sample retention , and remote control sampling functions.

 Water sampler 600BOQU water sampler 600

Technical Features:

1) Routine sampling: timing, time equal ratio, flow equal ratio, liquid level equal ratio and external control sampling;

2) Bottle dividing methods: parallel-sampling, single-sampling and mixed sampling etc bottle dividing methods;

3) Excessive sample retention: uses in conjunction with online monitor, and automatically retains water sample in the sampling bottles when monitoring abnormal data;

4) Power-off protection: Automatic power-off protection and it will automatically return to work when power on;

5) Record: has a function of sampling records, records for opening and closing doors and power off records;

6) Digital temperature control: precise digital temperature control of chill box, additionally equipped with soaking system which makes the temperature uniform and accurate.
