The PSB is a completely self-contained portable peristaltic sampler, providing the most economical choice for basic composite sampling needs.
It comes with bottle full shut off switch, contact closure input, and residen time and flow-based programming. (See the Ordering Information for available options.) The PSB is lightweight (less than 22 pounds with standard battery and empty bottle) and has a convenient carrying handle. When latched, it is rated NEMA 4X/ 6. Power can be supplied through a 12-volt battery or 110 220 VAC power supply.
Composite Samplng
The PSB is well suited for non-toxic applications. Dedicated to composite sampling, bottles are quickly and easily exchanged. The PSB is suitable for a wide variety of sampling applications in many locations, including manholes. Samples can be cooled by using ice packs or ice contained in a sealed bag.
Reliable Peristaltic Pump
Model PSB samplers use a field proven 1/4-inch ID peristaltic pump to collect samples. The pump is made of advanced thermoplastics to resist corrosion and promote longer tubing life. The pump rollers and tubing can be visually inspected without taking the pump apart. To reduce maintenance and replacement costs, the 1/4-inch ID pump uses Pharmed® long-life tubing. Unlike other samplers in its price range, the Model PSB sampler delivers consistent and accurate sample volumes by using fluid sensor technology coupled with sophisticated software.
Comprehensive, Flexible, Programming.
The Model PSB provides sampling programming that is unmatched in its price range. Its exceptional software is designed to be highly flexible and easy to use. The menu-driven system provides many programming features.
Versatile Controller
The PSB sets the standard in the sampler industry for performance and price. Its microprocessor-based controller offers advanced functionality and features such as data logging, review of settings and operating status, and a variety of flow and time modes. With its step-by-step menu format, dedicated button keypad, and large backlit LCD, the controller is simple to setup Clear prompts and shortcut keys enabling the operator to quickly change or review programming and settings, avoiding long, complicated menu structures.
Durable Construction
The PSB sampler case has thick walls made of impact and corrosion-resistant structural resin. Also, watertight connectors are provided for external power, contact closure/pulse input, and the optional 4 20-mA input. The case has a limited lifetime guarantee, just one of the many reasons this well-built sampler is an excellent value for its price category.
