Scoop sampler with unique sampling container fixation that makes it possible to change,without using other tools or accessories, the lateral attachment of the container with adjustable angle of telescopic grip, to swinging – for sampling from narrow or deep shafts. It is easy to attach other sampling containers, made from glass or stainless steel, with diameters from 90 mm to 120 mm. All parts that come into contact with the sampled liquid, including the last section of the telescopic bar, are made of non-corrosive materials (stainless steel, PP, TPU, PA). The  container fixation is easy to disassemble and to decontaminate. The last section of the bar is sealed and therefore liquid-proof. You may select standard or shortened version of the four-section telescopic bar for problem-free transportation in a car trunk.

Zone sampler for vertical profile sampling of water from weak-flow containers. The samples is taken in a cylinder with caps on both ends. Before sampling, caps must be secured in open position using a split pin at the end of the string. After submerging the sampler to the required depth, pull the string quickly upwards to free the closing mechanism and close both ends of the sampling cylinder. This will preserve the liquid sample from the required depth in the cylinder. After removing, the sample can be poured in a sample container, or the closed sampler can be hung in suitable place and you may observe the sample sedimentation through the transparent cylinder wall.

Portable sampler for one-time water sampling in the field. The built-in peristaltic pump enables sampling from the depth of down to 7.5 m. Pumping rate can be adjusted smoothly from 0 to 2.9 l /min (depending on the sucking height). The pump is controlled by a switch that selects the rotation direction (sucking – blowing). The pump head (including hose) is easy to replace due to its ingenious design. The sampler is fed from a 12V/12Ah internal battery providing long operation with a single charging. For easy manipulation, the unit has a grip and it is equipped with a shoulder strap. The sampler is supplied with a 5m sucking hose, terminated and equipped with a filter. The battery charger must be ordered separately.

DUO SAMPLer water sampler provides two independent sampling systems, including control electronics. These samplers can be equipped with SIMPLY SAMPler or SOFT SAMPler control electronics and made in stationary and portable (mobile) versions. The sampler can be used for synchronized sampling (controlled from a single control unit) from two sewers or two depths, while samples can be blended in a single container or stored separately. Each sampling system can be controlled independently, offering numerous options in sewer water quality monitoring. The sampler features are identical with standard devices.

The PISTON SAMPler sampling system is designed for water sampling from pressure piping. The sampling system consists of a piston that slides into the piping profile via a fitting. During the back stroke it pulls the sample from the piping in the chamber and releases it in the sample container. The system is driven by pressured air.

SLUDGE SAMPler is designed for sludge sampling from pressure pipelines (up to 6 bar). Sample taking, including blowing of the supply pipe, is done by compressed air. (Air compressor is not included). Sample taking begins with pressurizing the sampling system to higher pressure than the pipeline and the detection of any leakage. The supply valve is then opened and the overpressure in the system cleans the supply pipeline. The sediment flow into the sampling chamber is controlled by expansion receptacle. Once the pressures in the system have been balanced, the compressor pressure pushes the excess sample volume back to the pipeline and the supply valve is closed. In the final stage, the sample is drained into the sampling container. Samples can be taken in regular time intervals or upon impulses from flowmeter after a defined amount of sediment has flown through.

Automatic sampler FLOW SAMPler is designed for sampling from low-pressure pipelines enabling draining of water flowing through the sampler to the drainage. The sampler uses the principle of flow switch – between sample taking the water flows through the sampler system, while during sample taking the flow is “switched” to the sampling container, where the sample is measured and the “switch” is returned to its initial flow position. Samples in the preset volume of 50 - 500ml are discharged directly, or via splitter to the cooling or freezing box. Samples are taken upon commands from superior system, or according to program set in the sampler controller. The microprocessor controller is controlled via backlight display. Its memory logs all operational data. Inputs and outputs are prepared to be connected with the control system.

Easy-to-use automatic water sampler that meets demanding requirements for programming, logging and connecting of external signals. The sampler is controlled by Bond–OO-checK external memory, with real time circuitry. Before you start the sampling, use a PC to select the required sampling mode in the BOND-oo-CHECK. Launch the sampler by connecting the Bond-OO-checK to the sampler. Once connected, use the button to calibrate the required sample volume. The sampler status is indicated by the button backlight and the three-color LED on the BOND-oo-CHECK. The used sampler operation system requires neither display nor keypad, ensuring easy operation.

Simple automatic water sampler with all basic options for sampling in time, volume, flow and phenomenon-based modes. Sampling is provided by a peristaltic pump. Before each sampling, the pump reverse flow blows the hose, and the same occurs after the sampling. The hose can be washed several times with the current sample before each sampling – the liquid is sucked only up to the pump and then discharged.

The sampler is controlled by a graphic display and 6 buttons. The sampler features peristaltic or vacuum sampling. The sampler can be equipped with a container distributor. Sampler outputs can be connected to a control system. Repeated sampling on a selected weekday can be used as well.
