The simplest kind of stream sampler is a drift net,
similar to a ring net but lashed to a square frame.
Stakes pass through eyes welded to the side and are pushed
into the substrate. Organisms can be collected above and below
the surface. Nets are constructed of 500 micron mesh and are
12″ x 12″ x 1 meter long.
||Drift Net, 250 Micron Mesh
||Drift Net, 500 Micron Mesh
The Hess sampler consists of a circular aluminum frame, which is pushed into the substrate.
The substrate is stirred up, and organisms are washed into the collecting bag by the current
flowing through the mesh covered opening. The net screen wraps around the frame and is
secured with velcro and thus removable. Frames and mesh are sold separately.
Please note that the Hess Samplers are made up as required.
Please allow a few weeks for manufacturing.

The Surber Sampler is a small easily portable stream bottom sampler. It consists of
two folding brass frames, which are affixed at right angles and locked by braces.
After the horizontal frame is "seated" in the substrate, the silt is stirred up
and each large rock within the frame is upended so the current can wash the bottom
organisms into the net.
Custom mesh sizes are also available, but please allow a few weeks for manufacturing.

GENERAL OCEANICS MECHANICAL FLOW METER:
These compact, mechanical flow meters are designed for measuring flow in lakes, rivers,
canals, estuaries, sewage outfalls, and offshore applications. They are ideal for
determining water speed, volume, or distance. These general-purpose flow meters
incorporate a precision-molded rotor coupled directly to a six-digit counter that
registers each revolution of the rotor and displays it similar to an odometer
(up to 999,999 equal to approximately 14.5 nautical miles). The counter is located
within the body of the instrument and is displayed through the clear plastic housing.
Flow meters are properly balanced so they maintain a horizontal position when suspended
by a towing line. After completing each sampling, simply remove the meter and record the
reading and time. By subtracting the first reading from the second, the average speed over
a given sampling time can be calculated. Each flow meter measures 8-3/8″ long, 1-9/16″
in diameter and includes 18″ of towline and a stainless steel connecting axle pin.
High-speed impeller measures from 10 cm/sec. to 70 cm/sec.

and has a stainless steel swivel fitting. Ideal for measuring flow in hard to

BRIGHT DYES™ FLUORESCENT DYES:
These fluorescent dyes provide a higher degree of environmental safety and can be used on potable water.
Depending on concentration, the dye color ranges from a bright dark red to magenta color.
One tablet in 60 gallons of water gives a strong visual concentration of 1 ppm, or one tablet in
600 gallons of water will give a light visual concentration of 100 ppb. Sold in bottles of 200 Tablets.
||Red FWT Dye, Bottle of 200 Tablets

BRIGHT DYES™ FLUORESCENT DYES:
-Fluorescent water tracing dyes.
-NSF certified for use in potable water.
Ecologically safe dyes for use in stream tracing, lake studies, flow mapping, storm and
sewer analysis, pollution studies and leak detection. Two formulations: FWT Red, a
specially formulated version of the dye Rhodamine WT; and FLT Yellow/Green, a
formulated version of the dye Fluorescein. The fluorescent colors can be detected
visually in most water conditions or with the use of ultraviolet light or a fluorometer.
The dyes are temporary and will degrade naturally in sunlight (2-3 days for Red and
5-7 days for Yellow/Green) or with the addition of chlorine. Yellow/Green is resistant to
absorption in organic matter and should be used in water with heavy sediment loads.
