WS 316 SR Self-Rinsing Sampler
With automatic rinsing of the complete sampling line (suction hose, metering glass and distributor hose) using clean water, the WS 316 SR is the ideal sampler for heavily soiled sample media. In addition to specifying the frequency of rinsing, the components to be rinsed can also be selected.
The WS 316 SR features the same benefits as the WS 316, and in addition offers the following functions:
- Separate drain for rinse water in sample storage chamber
- Drain position accessed directly by XY Distributor
- Numerous bottle combinations up to 35 x 1 l bottles; even customer-specific bottles can be used
- Available with warm water rinsing if desired, e.g. for greasy media
- Optional upgrade to system with automatic dosing of cleaning agent when rinsing
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.
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.
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.
Depending on conditions and requirements, samplers are available with diverse sampling systems:
Direct Bottle Filling with Numerous Possibilities
Our XY Distributor system has been in use successfully for nearly 20 years. Its wide array of possibilities, reliable operation and minimal follow-up costs have made it the distributor of choice among our customers. The two-axis system makes full use of the entire sample storage chamber by using coordinates to travel and locate bottle positions.
