Portable Sampler Vacuum, VST3B2AA2C2

Manning portable samplers provide accurate‚ repeatable sample volumes for a wide range of applications. The vacuum-style sampler has a rugged NEMA 4X/NEMA 6 ABS housing with stainless steel hardware that stands up to the harshest sampling environments. These features‚ along with watertight connectors‚ ensure long service life.

The controller’s large backlit display is simple to set up‚ even in the dark! It offers advanced features such as datalogging‚ review of settings and operating status‚ and a variety of flow and time-based operating modes. Simple prompts and a 24-key keypad‚ including shortcut keys‚ save time by avoiding frustrating navigation through long‚ complicated menus.

You can add up to 15 lbs of ice to the sampler housing to maintain the EPA-recommended 4°C even in high ambient temperatures. An optional suspension harness is ideal for hanging the sampler in manholes and other tight spaces. At 25 lbs‚ the VST can be easily transported to remote sites.

VST vacuum samplers feature a high 5 ft/sec transport velocity. They deliver sample volumes within 0.5% of pre-set volumes versus the ± 5.0% typical of most peristaltic samplers. Changes in vertical or horizontal head height will not affect the sample volume taken. Due to the high transport velocity (5 ft/sec versus the EPA recommended minimum of 2 ft/sec) of samples taken by the VST sampler‚ you can be assured you are receiving the most representative sample possible.

Sample programming includes but is not limited to: flow proportional pacing (contact closure)‚ totalized flow pacing (analog input)‚ flow pacing with time override‚ flow pacing with delay sampling‚ flow pacing with maintained event sampling‚ uniform and non-uniform time intervals‚ multiple bottles per sample‚ multiple samples per bottle‚ multiple bottle compositing‚ bottle grouping‚ sampling based on external input device‚ program delay (time or flow)‚ stormwater sampling‚ data logging (512 event capacity). The internal clock indicates real-time with ±1 minute per month accuracy. Features a 5-year lithium backup battery to maintain program logic‚ RAM‚ and clock. Also features contact closure and 4-20 mA input; RS-232 output (optional).

BUNDLE INCLUDES: The sampler is a single-bottle configuration. SAMPLER: VST;  BATTERY: 12-VDC SLA 8ahr‚ BATTERY CHARGER: 3 Stage 850 mA SLA;  INPUT: contact closure and 4-20 mA with 3’ input cable;  BOTTLE: PE 2.5 Gallon round carboy;  INTAKE HOSE: 25 ft of 3/8″ ID PVC hose and PVC/Stainless strainer.
