Fully Automatic Emptying and Rinsing of Sample Bottles
WS 316 SE Self-Emptying Sampler
The fully automatic bottle emptying and rinsing function makes the WS 316 SE ideal for surveillance and other applications where samples are not regularly retrieved. Bottles are filled in sequence, and then automatically drained and rinsed with clean water if samples have not been retrieved. They are then available for the next samples.
The WS 316 SE features the same benefits as the WS 316, and in addition offers the following functions:
- Direct distribution for 2 to 24 bottles to ensure samples remain free of cross-contamination
- Available with second sampling system and composite container for additional samples, such as event-proportional samples (see photo)
- Pull-out bottle tray for easy retrieval of samples
- Sample retrival at the touch of a button releases samples directly into transport container, without tap and therefore without cross-contamination
- If required, sample storage chamber can be provided with lock and/or monitoring of door movements
- Optional viewing window in door for sample storage chamber
- Additional monitoring of bottle fill level possible
Controller
WaterSam controllers feature user-friendly operation and reliability. Both controller types not only enable to the activation of programs at the same time, they can be also run simultaneously.
Custom software modifications can easily made upon request.
Standard Controller
The standard WaterSam controller is suitable for a wide variety of applications. Its 4-key user interface is easy to operate, and yet it offers the possibility of running up to 9 sampling programs at the same time. In addition, the standard controller has multiple menu levels, enabling the user to set a code that restricts access to certain menus. The 4 analog inputs and 10 digital inputs enable time-, volume-, flow-, and event-proportional sampling.
A built-in RS-232 serial port permits communication with external devices. With an optional modem, even remote control is a possibility.
MS3
The WaterSam MS3 controller offers user-friendly operation in addition to a range of communications possibilities and the ability to retrieve data from internal and external sources.
Despite the wide-ranging possibilities available, sampler operation is very user-friendly thanks to the 24 keys and large graphic display. Color-coded direct function keys serve to start, pause and stop selected programs. A grab sample can be taken simply by pressing the blue key.
Intelligent sensors can be connected directly to the controller, without the need for a transmitter. If desired, a variety of data can be accessed and retrieved via a USB port.
Sampling Systems
Depending on conditions and requirements, samplers are available with diverse sampling systems:
*Requires special housing or external mounting of sampling system
Sample Distribution
Direct Bottle Filling with Automatic Emptying and Rinsing
Mehrere verschiedene Revolververteilersysteme, von 4 bis zu 24 Flaschen, und ein System mit 2 PE-Flaschen sind erhältlich.
Die Flaschenentleerung zur Mitnahme ins Labor erfolgt über Knopfdruck. Die Probe fließt direkt aus der Probenflasche in den Beförderungsbehälter. Kein weiteres Verteilsystem (Querverschmutzung!) ist notwendig.
Werden die Proben nicht abgeholt, so wird jede Flasche automatisch entleert und gespült bevor sie dann wieder neu befüllt wird
