ProfiLine 3000: New Single-Parameter Handhelds from WTW

WTW GmbH proudly announces their new ProfiLine 3000 series of single parameter handheld instruments. All models have a rugged waterproof housing with IP 66/67 protection class. A separate battery compartment allows easy exchange of batteries or the use of rechargeable batteries. A technical highlight is the special silicone keypad with sealed surface and the feeling of ‘real’ keys. It provides an excellent operation and is easy to clean. The instruments have continuous operation times of up to 2500 h with one battery pack (4 x 1.5 V AA). Three model lines are offered:

• The 3110 Series for pH or conductivity measurement are functional and easy-to-use handhelds for standard measurements.

• The 3210 Series for pH, D.O. or conductivity measurement has a backlit graphical display, a plain text menu and a special CMC function to ensure that the measurement is taken within the calibration range. The series also has enhanced measurement capabilities.

• The 3310 Series for pH, D.O. or conductivity measurement is a true highlight: An automatic datalogger with memory for 5000 records and a 100% waterproof USB interface make them perfect for long-term recording in the field and for fast data transfer to a laptop or PC.
