WS 312 Stationary Sampler
The WS 312 is a space-saving sampler for all standard indoor and outdoor applications. With its built-in cooling and heating, samples are stored reliably at the desired temperature.
- Weather-proof housing and roof made of durable stainless steel; upper panel door included
- 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
- 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 XY Distributor for direct filling of numerous bottle sets without cross-contamination
- Simple upgrade to monitoring station can be made at anytime
- Wide range of optional equipment: housing materials, pumps, valves, etc.
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:
*Requires special housing or external mounting of sampling system
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.
