Zetian - Model WDet-2000 - Water Quality Automatic Sampler
WDet-2000 Auto Water Sampler is a kind of intelligent multi-function water sampling device. It adopts innovative integrated Water Over-standard Sample Retention Technology, compatible with over-standard sample retention and regular sampling function. The sampler can realize automatic pipeline cleaning, multiple sampling methods based on water sampling requirements (consisting of timing sampling, time equal-proportion sampling, flow equal-proportion sampling, remote control sampling and over-standard sample retention) and various bottling methods (including single sampling and mixing sampling). Single sampling indicates each bottle has one sampling while mixing sampling indicates every bottle has multiple samplings.
● Industrial-grade real-time operation system, with fast response, stable running and strong extension
● Innovative integrated Water Over-standard Sample Retention Technology, compatible with over-standard sample retention and regular sampling function
● Large capacity of sampling bottle chamber, keep constant temperature at 4±2℃
● Compact sampling structure; accurate and stable sampling filling action; novel pipeline design
● Pipe of automatic sampling unit is a kind of rigid PVC pipe. Sampling pipe has no sewage residue, ensuring authenticity of the samples.
● Automatic sampling unit sets manual comparison sampling port of mixied water samples
● During single sampling, sampling quantity and sampling bottles can set freely, with higher flexibility
● Over-standard sample retention pump is placed inside the sampler, greatly reducing vibration and noise during sampling
● With high intelligence, configuring with real-time network communication interface (RS232 and RS485) to receive information of upper computer and designated control device, realizing remote sampling setting, execution and response function
● Separation of water and electricity as well as complete separation of control part and mechanical water taking part guarantee safety and stability of the equipment
● Control part employs advanced embedded application system, with strong intelligent sampling function, which can conduct multiple sampling methods based on sampling requirements of users, including timing quantitative sampling, time equal-proportion sampling, flow equal-proportion sampling, remote control sampling and over-standard sample retention, etc.
● A/B storage tank is placed inside the refrigerator and protected by electronic password access to ensure the stability and safety of water samples
● Allocation of water sample adopts rockerarm to fill directly without diversion disk, avoiding cross contamination of water samples
● With power-off protection function, the sampler can restore the working state before outage without losing any data; UPS is optional
