Overview
The water quality automatic sampler has protection functions such as password protection, power failure protection, etc. It can realize sampling according to timing, time and other proportions, flow and other proportions, external control sampling, serial control and other methods. It can also achieve mixed parallel sampling and remote sampling. Control sampling, remote parameter setting, and other functions. Suitable for environmental monitoring stations at all levels, sewage treatment plants, water conservancy, w......

Details
Executive standard:
HJ/T372-2007 "Technical Requirements and Testing Methods for Water Quality Automatic Sampler"
Features:
1) Separate bottles and keep samples: the instrument can realize 1～24 bottles to keep samples, and the number of bottles can be set freely.
2) Sampling function: multiple sampling methods such as timing sampling, time ratio, flow ratio, external control sampling, and serial port control can be realized.
3) Sample retention function: It can record the sample bottle number, sample retention time, sample volume, COD value and NH3-N value of each sampling, and can record the latest 1000 data records.
4) External interface: flow meter analog interface, RS485 interface.
5) Power-off protection function: After the instrument is powered off and re-powered in the running state, the instrument can automatically restore the original running state, and the instrument parameters will not be lost after the power is off.
6) Automatic emptying function: every time the sampling is completed, the system can automatically empty the water in the pipe to ensure that the sampling pipeline does not cause sedimentation and blockage.
7) Anti-overflow function: The user can set the number of sample bottles, and stop the sample after completing the reserved samples of the set number of bottles.
8) Water sample refrigeration function: the use of high-efficiency refrigeration devices can keep the retained water samples in an environment of 0°C to 4°C.
