  • Adapter for connecting pH electrodes with BNC plug to a meter with DIN socket.

  • pH/ORP electrodes are the most commonly used electrochemical sensors. At the same time, they provide the most sensitive measuring signals and must be serviced and calibrated on a routine basis. The concept of IDS sensors precisely takes effect here. Digital data transfer without interferences…

  • MPP IDS – the digital multi-parameters (up to three main parameters) depth probes with built-in depth measurement to use in profile measuring Depth measurement of pH, conductivity, dissolved oxygen, turbidity - up to three main parameters simultaneously, including depth and…

  • The calibration and storage containers for the WTW oxygen sensors are suitable for the standard conform calibration (DIN ISO 5814 or DIN ISO 17289: 2014-12) with water steam saturated air as well as for storage of the sensors to protect the sensitive membrane.

  • Flow vessels for WTW conductivity measuring cells are perfectly designed to perform measurements without the interference of carbon dioxide through the air or to examine the conductivity of solutions in closed circuits. Important: The overpressure in the system must not exceed 0.5 bar.
