H220X sensor transmitter

The H220X transmitter is a full-function loop powered transmitter. It has a modular design and can be specified for use with traditional pH, ORP, 2/4-pole conductivity as well as inductive conductivity sensors. Two separate software packages described below can be choosen depending on the level of functionality needed for the application.
