These instruments have to be used in conjunction with the HI 8936 transmitter series (seepage 49). Thanks to this installation it is possible to receive a signal without any noise froma distance of up to 300 meters from the measuring point. The dosing type is selectable througha jumper on the rear panel. Four different models are available with different measurement
ranges, each one to be used with the corresponding HI 8936 model. The output configurationfor connecting a recorder or a PLC can be chosen between 0-20 or 4-20 mA.The front panel is protected behind a transparent splash-proof cover.
