Remarkable Versatility and Impressive Capacity
WS 316 Stationary Sampler
Whether for indoor or outdoor use, the WS 316 is an all-rounder that impresses with its generous storage space and expandability. It can be tailored for a wide variety of different sampling requirements and conditions, and can even be retrofitted later with other equipment. The WS 316 even has room for extended bottle sets.
- Housing and roof made of durable stainless steel
- Three separate technical compartments in the upper section of the sampler to protect the pump, electronics and refrigeration unit
- Freely adjustable and highly accurate temperature control for the sample storage chamber, for ambient temperatures from -25°C to +42°C – optionally from -40°C up to +55°C
- High-performance vacuum sampling system – alternatively available with any other WaterSam sampling system
- Borosilicate glass metering vessel protected in sample storage chamber to minimize sample falsication that could stem from temperature extremes
- Hose inlet on the left and right side; optionally from below
- Available with a composite container up to 60 l, or with an XY Distributor for direct filling of numerous bottle sets (up to 49 x 1 l or 64 x 350 ml) without cross-contamination
- Wide range of optional equipment: housing materials, pumps, valves, equipment of challenging sample media and environments, sample freezing, etc.
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:
Sample Distribution
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.
