The VAR-B system for flow-proportional sampling utilizes the vacuum/pressure principle as well as special technology for contactless sample volume metering. This makes it especially well-suited for very dirty sample media.
- Fast volume metering
- Minimizes sedimentation in the metering vessel
- Limits the max. volume to be drawn
- No electrodes to clean
- Simple switching to fixed volumes
| Sample Media | Pure/ultrapure water to very dirty water/wastewater |
| Sampling Modes | Time-, volume-, event-, flow-proportional |
| Sample Volumes | Variable (dependent on flow) or fixed; adjustable: 20 - 250 ml Optional: larger volumes |
| Wetted Parts | Borosilicate glass (dishwasher-safe; resistant to acid, alkali, and temperature shock), silicone, PVC, stainless steel Optional: custom materials upon request |
| Available for | WS 98, WS 312, WS 316, WS 316 SE, WS 316 SR |
