Function Features

Multiple triggering modes	It can realize various sampling triggering modes such as timing, time proportional and manual sampling;
Bottle sampling function	The instrument can realize single bottle sampling and multi-bottle automatic bottle sampling;
Mixed sampling	Water samples collected multiple times can be placed in the same sampling bottle;
Sampling record function	With sampling records and power outage records;
Power failure protection function	When the instrument is powered off and then powered on again during operation, it will automatically resume its original operating state, and the instrument parameters will not be lost after the power failure.
Automatic emptying	After each sampling is completed, the pipeline is automatically emptied and the sampling head is back-flushed to ensure that the sampling pipeline is not blocked by sediment;
Automatic rinsing	Before each sampling, the pipeline is rinsed with the water sample to be tested to ensure the representativeness of the sample;
Water sample storage	Stored at room temperature;
Delay start function	Start sampling after the delay time is reached;
Battery power supply	Lithium battery power supply is used to ensure the normal operation of the instrument for two days;
Appearance structure	Integrated design, easy to carry;
Sampling program	Users can set and save common sampling programs;
Protection level	IP65, all 304 stainless steel shell, can be used in rain and water;
Short-range wireless control function	Using a wireless handheld controller, the sampler can be remotely set up, controlled, and status checked;
Retractable bracket	An optional bracket with a manual winch is available to facilitate the removal and placement of the sampler in the well.

Application Overview

This sampler is mainly used for sampling in sewage inspection wells. It has a stainless steel shell, is powered by a lithium battery, is sling-mounted, and can be operated by remote control at close range. It is suitable for long-term unattended automatic sampling underground and is an ideal tool for inspection well sampling by environmental monitoring departments, urban construction departments, drainage companies, and third-party testing agencies.

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).
