Comprehensive Overview of the PRE917B Automatic Water Sampler
The PRE917B Automatic Water Sampler is an advanced device designed to support automatic water quality monitoring stations, particularly in river sections and drinking water sources. It integrates seamlessly with various online monitoring systems, allowing for efficient and reliable sample collection and storage.
Application Overview
The PRE917B Automatic Water Sampler is primarily utilized in conjunction with automatic water quality monitoring stations. It operates under the control of an on-site industrial computer, coordinating with wired monitors to ensure comprehensive water quality analysis. In instances of abnormal monitoring or special sample retention needs, the sampler automatically saves backup water samples in low temperature refrigeration, making it an indispensable component of water quality monitoring stations.
Automatic Water Sampler Features
- Regular Sampling: Offers multiple sampling modes including timing, time proportion, flow proportion, liquid level proportion, and external control sampling.
- Bottle Separation Methods: Supports parallel sampling, individual sampling, mixed sampling, and other bottle separation techniques for versatile sample management.
- Synchronous Sample Retention: Allows synchronous sampling with online monitors for accurate data comparison.
- Remote Control (Optional): Enables remote status queries, parameter settings, record uploads, and control sampling via remote access.
- Power Failure Protection: Features automatic protection during power outages, resuming work automatically when power is restored.
- Sampling Records: Maintains a record of all sampling activities.
- Low Temperature Refrigeration: Utilizes compressor refrigeration to store samples at 2℃-6℃ (±1.5℃).
- Automatic Rinse: Ensures representativeness of retained samples by rinsing the pipeline with the water sample before each sampling.
- Automatic Emptying: Empties the pipeline and blows back the sampling head after each sampling session.
