The sampler is primarily used in automatic water quality monitoring systems for river cross-sections and surface water sources of drinking water. It can be controlled by on-site industrial computers and integrated with various online monitoring instruments. Body, coordinate work, and when there are detection anomalies or special sample retention requirements, it achieves automatic sample retention, automatic draining of water samples, and automatic sealing of bottle openings. It is an automatic surface water quality monitoring system.Essential components. Routine Sampling: Scheduled, Proportional by time, Exceedance retained sample, Concurrent retained sample, External control sampling. Bottling Methods: Single bottle, double bottle, and other bottling methods. Simultaneous Sample Retention: Synchronized sampling and retention with online monitoring instruments for data comparison. Automatic Emptying: Capable of automatically emptying leftover water samples from sample bottles. Remote Control: Allows for remote status inquiries, parameter settings, and remote sampling, etc. Automatic Sealing: The cap of the sample bottle can automatically seal. Record: Alarm records, sample retention records, door opening/closing records, power outage records. Sample Failure Alarm: Automatically save the sample failure alarm record when water sample sampling fails. Access Control System: Electronic lock password unlocking, automatic recording of sample box door opening and closing. Power Failure Protection: Automatic protection during power outages, automatic resumption of operation upon power restoration. Low Temperature Refrigeration: Compressor cooling0°C to 20°C adjustable as desired.
