Omega pH/ORP Preamplifier PHTX-22

The PHTX-22 is a 10-40 volt dc powered preamp. Power can be provided by the excitation of a process meter (such as the DPi8) or the optional power supply. The electrodes are entirely encapsulated in a compact epoxy filled enclosure designed for easy mounting in a manufacturing process. The PHTX-22 offers redundant outputs from either a BNC connection, terminal strip or both at the same time.
