ISCO 6712 FULL-SIZE PORTABLE SAMPLER. Includes controller, top cover, center section, base distributor arm, two pump tubes, instruction manual and pocket guide. Also includes 24 bottle (24 x 1 L polypropylene) configuration, 25 ft suction line and strainer, and two Model 934 Ni-Cad battery packs and battery charger.


ISCO 2150 AREA VELOCITY FLOW MODULE. The 2150 Flow Module uses continuous wave Doppler technology to measure mean velocity. The sensor transmits a continuous ultrasonic wave, then measures the frequency shift of returned echoes reflected by air bubbles or particles in the flow.


ISCO 4110 ULTRASONIC FLOW LOGGER.  For flow measurement in streams containing harsh chemicals, grease or suspended solids.  The logger features a non-contacting sensor that quickly and easily installs above the flow stream.


ISCO GLS WATER SAMPLER.  Automatic composite water sampler, which comes complete with nicad battery pack, charger, suction line, strainer and sample bottle.


ISCO 750 AREA VELOCITY LOW PROFILE MODULE. The sensor on the 750 module uses Doppler technology to directly measure average velocity in the flow stream. An integral pressure transducer measures liquid depth to determine flow area.


GLOBAL FLOW PROBE – This is a highly accurate, lightweight water velocity instrument that is excellent for storm water runoff studies, measuring flows in streams, rivers and partially filled pipes.  The anodized aluminium telescoping handle is available in lengths that extend from 5ft. to 15ft.


WILKS INFRACAL TOG/TPH ANALYZER.  This unit provides an easy infrared analysis method for on-site measurement of total oil and grease (TOG), and total petroleum hydrocarbon (TPH) in water and soil samples and fat, oil and grease (FOG) levels in water samples.  It can read out infrared absorption values or they can be calibrated to display concentrations directly in any desired format such as ppm or milligram/kg.
