The PT4 Monitor is a multichannel monitoring and control system for measuring dissolved oxygen, temperature, pH, salinity, gas pressure, TDGP, ORP/Redox and conductivity and can be used with any sensor providing a 4-20 mA output. It can display up to eight measurements and monitor up to eight digital inputs simultaneously. The PT4 has data logging, PC connectivity and control capabilities and includes a display monitor and a junction box to which the various sensors are connected. It is designed for outdoor use and can be supplied with a number of mounting and enclosure options.
