Frequently Asked Questions

Q: How does the WS-9300/9350 prevent sample contamination?

The system employs an automatic pipe rinsing function that flushes the lines before sampling, combined with programmable pre- and post-sampling drainage and filtered sampling heads to prevent sediment buildup.

Q: Can this sampler operate in extremely cold climates?

Yes, the WS-9300/9350 is designed for temperatures as low as -30°C, featuring dedicated heating modules in both the refrigerator and the pump area to ensure uninterrupted operation.

Q: What are the available power options for field deployment?

It supports three versatile power modes: AC 110V/220V for permanent installations, DC 12V tinned cords for battery use, and a standard car cigarette lighter plug for mobile sampling.

Q: How does the flow-proportional sampling mode work?

By connecting an external flow meter via the 4-20mA analog input, the sampler automatically triggers a sample based on a predefined volume of water passing through the system.

Q: Is the device protected against power outages?

Yes, the system includes power-off protection that ensures all parameter settings, system clock data, and sampling records are preserved when power is lost and restored.

Q: How is the peristaltic pump tubing maintained?

The system features a "Pump Lifetime Reminder" where users can set the operating time limit; the device then prompts the operator to replace the tubing upon expiration to maintain accuracy.
