FAQS

Frequently Asked Questions FAQ About Soil Tester

What is an industrial online water sampler and how does it work?

Industrial online water samplers (like our [Product Series]) are automated devices that collect water samples at preset intervals for chemical/physical analysis. They use programmable controllers to extract representative samples from pipelines/rivers, ensuring compliance with EPA and ISO standards. Key features include: Ultrasonic cleaning to prevent biofilm buildup 4-20mA output for SCADA integration Depth-adjustable probes (up to 50m for deep-water sampling)

Why choose an online sampler over manual sampling?

Online samplers eliminate human error and provide: Real-time data for parameters like pH, turbidity, and heavy metals; 24/7 operation during storms or emergencies (e.g., LCRR-mandated lead testing); Chain-of-custody logs meeting EPA 1664A standards for oil-in-water analysis;

How to maintain water samplers for accurate results?

Maintenance protocols derived from Hach and Burkert systems include: Monthly flow cell calibration with NIST-traceable standards; Quarterly sensor validation (e.g., EXO Sonde wipers for biofouling); Annual seal integrity checks for underwater deployments.

Can your samplers handle corrosive/high-sediment water?

Our titanium-housed samplers support: Acid mine drainage (pH 2-4) with sapphire optical windows; High-TSS wastewater (up to 10,000 mg/L) via anti-clogging inlets; Marine environments with IP68-rated enclosures.

What certifications do your samplers have?

Compliant with: SDWA (Safe Drinking Water Act) for municipal use; ISO 15839 for performance testing; CE/ATEX for hazardous areas (Zone 1/21).
