WTW has two new rugged hand held meters for spot measurements in the field and in process. They are extremely precise, rugged and waterproof (IP 67) and work with all modern conventional WTW sensors. A backlit display with plain text for easy operation, a memory for 5000 GLP compliant measuring data and a waterproof USB interface for fast data transfer to PC or laptop makes them compact tools for many applications. A built-in time controlled data logger provides automatic data sampling with intervals between 1 s and 60 minutes.
