Details
±5% of 200 mL sample volume with: 4.6 m (15 ft) vertical lift, 4.9 m (16 ft) of
in. vinyl intake tube, single bottle, full bottle shut-off at room temperature and
1524 m (5000 ft) elevation
±5% of 200 mL sample volume with: 4.6 m (15 ft) vertical lift, 4.9 m (16 ft) of
in. vinyl intake tube, single bottle, full bottle shut-off at room temperature and
1524 m (5000 ft) elevation
Pacing: Fixed Time, Fixed Flow, Variable Time, Variable Flow, Event
Distribution: Samples per bottle, bottles per sample and time based (switching)
Continuous or non-continuous
0.9 m/s (2.9 ft/s) with: 4.6 m (15 ft) vertical lift, 4.9 m (16 ft) of
tubing, 21 °C (70 °F) and 1524 m (5000 ft) elevation
Ultrasonic. Body: PEI NSF ANSI standard 51 approved, USP Class VI
compliant. Contacting liquid detector or optional non-contact liquid detector
An air purge is done automatically before and after each sample. The sampler
automatically compensates for different intake tube lengths.
Intake tubing: 1.0 to 30.0 m (3.0 to 99 ft) length, ¼-in. or
ID PTFE-lined polyethylene with protective outer cover (black or clear)
Stainless steel, polyethylene, PTFE, PEI, silicone
Sample history: 4000 records; Data log: 325,000 records; Event log:
2000 records
USB and optional RS485 (Modbus)
Power, auxiliary, optional sensors (2x), USB, distributor arm, optional rain
gauge
AUX port: none; optional IO9000 module: Three 0/4–20 mA outputs to supply
the recorded measurements (e.g., level, velocity, flow and pH) to external
instruments
AUX port: One 0/4–20 mA input for flow pacing; optional IO9000 module:
Two 0/4–20 mA inputs to receive measurements from external instruments
(e.g., third-party ultrasonic level)
AUX port: none; optional IO9000 module: Four low voltage, contact closure
outputs that each supply a digital signal for an alarm event
AUX port: none; optional IO9000 module: Four relays controlled by alarm
events
