Two Programming Levels
Standard programming lets you set up typical sampling programs quickly.
Extended programming includes all features available in standard programming
plus additional features.
See Standard and Extended Programming on page 22.
Peristaltic Pump
•
Benefits
: Liquid moves continuously under pumped flow. The pump has no
metering chambers or gravity fed internal tubing to trap sediment or residual
liquid. Sample liquid contacts only the strainer, suction line, tube coupling, pump
tube, bulkhead fitting, and sample bottles.
LD90 Liquid Detector
•
Nonwetted Detection
: Sample liquid never touches the detector.
Two Line Purges in Sampling
Cycle
The sampling cycle always includes a presample purge and postsample purge that
clears the suction line of residual liquid.
Easy Grab Samples
Simply disconnect the pump tube from the bulkhead fitting on the center section,
and place the pump tube over your sample container. See Grab Samples on page
65.

Pacing
•
Uniform Time Pacing
: Sampling at regular time intervals.
•
Flow Pacing
: Sampling at regular flow-volume intervals.
See Pacing on page 79.
Distribution Methods
•
Composite
: Samples deposited in a single large bottle.
•
Sequential
: Only one sample placed in each bottle.
•
Samples Per Bottle
: Multiple samples placed in each bottle.
•
Bottles Per Sample
: One sample deposited in multiple bottles.
See Distribution on page 81.
Three Flexible
Start-Time Settings
•
Start Immediately
: Starts the sampling program immediately.
•
Delayed Start
: Starts the sampling program after a user-definable delay of
1 to 999 minutes.
•
Clock Time
: Starts the sampling program at a user-definable time on one
or more days of the week.
See Start Times on page 86.
Option for a Continuous
Running Program
•
Continuous Sampling
: If the sample bottles can be properly serviced, the
sample distribution can restart with the first bottle set after the last bottle
set is filled, without interrupting the running program.
See Distribution on page 81.

Pacing
•
Uniform Time Pacing
: Sampling at regular time intervals.
•
Nonuniform Time Pacing
: Sampling at irregular time intervals.
•
Random Interval Pacing
: Sampling at unique random intervals.
•
Flow Pacing
: Sampling at regular flow-volume intervals.
•
Event Pacing
: Sampling each time a user-definable event occurs.
