900 SERIES SIGMA
PORTABLE SAMPLERS
Field Convertible for Composite or discrete sampling
Designed to combine accuracy and convenience, the 900 series portable
sampler, with a three gallon polyethylene bottle installed, weighs only
28 lbs. This unique sampler is available with an interchangeable compact
or standard sized base and can be quickly configured in the field for
composite or discrete sampling. The efficient design and flip up handles
make carrying as easy as possible. In addition, this compact model can
be configured for single or multiple bottle applications. Unlike
samplers of conventional size, the compact-base model is specifically
designed for use in 18 inch manholes. The controller conforms to NEMA 4X
standards (capable of withstanding hose spray and submersion under 6 ft
of water for a minimum of 30 minutes), isolating all electromechanical
components while the keypad switches and display are covered by a
waterproof, corrosion resistant membrane. The sealed connectors (even
without capping) and pump shaft seal further protect the unit’s
environmental integrity. Once the sample is collected it’s kept cool
within the double-walled insulated base. The compact base holds 8-1/2
lbs of ice with Twenty Four 575 mL bottles in place, and the standard
base holds 32 lbs of ice with Twenty Four 350 ml bottles All Sigma
portable samplers include 6 amp-hour, 12 VDC batter, 115 VAC power
converter and battery charger, sample bottle (s) and 25 ft of vinyl
intake tubing with stainless steel strainer. |
