Portable Meters for the Standard Parameters of Water: pH, D.O. Conductivity

WTW is a leading manufacturer of measuring instruments for the standard parameters of water and offers a solution for every applicaton. If you need precision, portability, compact size, ruggedness and low power consumption for field use, then our 3xxi family of portable instruments should be your choice. These meters are available in four different grades:

1.The 315i series is for standard applications that require no automatic documentation and no enhanced sensor options. The series includes meters for the three most important standard parameters of water: pH/mV, D.O. and conductivity.

2.If you expect to use special sensors or additional calibration procedures (e.g. for D.O.), the 330i series is an ideal solution.

3.If you require flexibility and easy and reliable data transmission, the 340i series should be your choice. Within this series, there are available single parameter instruments for pH, D.O. and conductivity, as well as combination (pH/Cond, pH/D.O.) and multiparameter (pH/D.O./Cond) instruments.

4.The Multi 350i is a class of its own. Fitted with special sensors, this exceptional multiparameter instrument can measure, display and store up to 3 parameters plus temperature simultaneously.

Another different line of portable instruments is the VARIO line. These are quality pocket instruments for random sampling in

process control, fast lab and service applications and training scopes. The VARIO is available for pH/mV and
conductivity measurement.
