Device system equipped with vacuum technology for frostfree roofed installation with mains supply. This robust and compact instrument contains proven components and is easy to operate. Controls were reduced to an absolute minimum. The operator guidance is menu driven showing all relevant parameters in the display. Thus providing a system which is fully sufficient for a multitude of tasks at a very favorable price-performance ratio. The addition of the IsoBox and cable connection accessory components provides the user with an inexpensive version for 2 h composite samples. With this powerful and reliable device, the operator has a low cost sampling instrument at his disposal which is reduced to core functionalities.

The instruments of the PB 150-2 series with their numerous versions are stationary samplers for permanent outdoor use under rough ambient conditions. The instruments are equipped with low maintenance and self-cleaning vacuum technology which has been field-tested and proven over years in the wastewater engineering sector. The devices are a further development of the PB 150 series and offer even more powerful and more economical sample storage with complete stainless steel fitting and a technically optimized temperature control system with a forced-ventilation liquifier. With its independent operation from the control system, the multiple point regulation system for cooling and heating the sample storage unit offers safe temperature control, even when the control system is turned off. In the light of representative samples for subsequent analysis combined with water content assessment, thermostatic control plays an important role. With its overall maintenance- and service-friendly equipment configuration with separate energy, control and wet area and its variable control system with memory for user programs, the device offers a high degree of efficiency and availability. The “Var” version with a variable dosing container is available for users who wish to combine flow proportional sampling with the advantages of vacuum technology. This patented version guarantees a reproducible sampling volume which corresponds to the individual flow volume (0/4-20mA) and permits digital sampling volume adjustment. Sampling can be traced using the display or fully documented and programmed using the communication software which is linked to a PC by an interface.

For permanent stationary use in water and wastewater monitoring measuring networks, automatically self-emptying samplers are available from the PB 150-SE 12 series equipped with 12 or PB 150-SE 24 equipped with 24 sample vessels. These devices operate with proven low maintenance and self-cleaning vacuum technology. The sample vessels are available in glass (Duran 50) and are easily extractable for cleaning. The bottle is sealed and emptied by means of robust constriction hose valves. The fractioned sample in the device is automatically discarded (emptied) or manually extracted for analysis. Immediately after emptying a sample which is no longer required, the relevant bottle is rinsed with pressurized clean water before it is refilled. These devices can store up to 12/24 reserve samples without supervision. In case of serious disruption of operation or other events, event samples can be taken. The PB 150-SE devices are thus not only suitable for “around the clock sampling” for routine monitoring tasks, but also for event sampling or for a combination of both. Sampling is traceable by means of the program and error memory readout on the display or can be documented and programmed from a PC using the communication software.

Portable sampler PB 13 with vacuum technology for universal applications. Thanks to its energy saving functionality, a large number of sample cycles or comprehensive sampling programs, respectively can be performed with just one battery charge. PB 13 can be mounted directly on all common storage containers or onto the IsoBox, which is available in different versions. When combined with IsoBox, it provides the user with a practical and modularly extendable system with passive cooling. IsoBox is not only suitable for temperature control of samples but also for safe protected sample transport.

The portable sampler PB 17 with vacuum technology and its immensely compact build is also suitable for field use in difficult terrain. With its large utilizable sample capacity of 24 x 1 l segment bottles, it is particularly suitable for extensive monitoring tasks and load determination. The lower part of the device has a double-wall insulation and offers full sample protection and a passive cooling facility with dry ice or cold storage accumulators. The cover, which is equipped with a lock, offers protection against the elements and unauthorized access. Its easy-to-change rechargeable battery with plug connection prevents downtimes caused by battery charging and facilitates a high level of availability.

Portable sampler PB 25 S with peristaltic-pump dosing system and integrated rechargeable battery for collected samples 26 l as well as fractioned samples via turnable distributor on 12 x 1 l, 24 x 0.5 l or 24 x 1 l sample containers. Thanks to the linked non-contacting water recognition (optional) also waters with considerably low or high conductivity can be precisely sampled.
