Portable electrochemical measuring instrument WTW
pH, ORP, Cond, DO

WTW’s well-known „3xxi“ family of portable measuring instruments is available in four differrent product ranges:

1) For standard applications which do not require automated documentation nor extended sensor options, the 315i series is adequate. The customer can choose an instrument for either of the main standard electrochemical parameters pH/mV, DO and conductivity.

2) If special sensors (particularly such for conductivity measurement) or additional calibration procedures are to be employed, the 330i series instruments are a good choice.

3) Anybody seeking flexibility regarding the employment of sensors plus comfortable and reliable data transfer, will opt for the 340i series. This range includes not only single parameter instruments for pH, DO and conductivity, but as well combination instruments for pH/cond, pH/DO, and multiparameter (pH/DO/cond).

4) The multiparameter instrument Multi 350i takes in an outstanding position within the WTW range. By means of special sensors, this instrument can measure and store up to 3 parameters simultaneously.
