Rosemount two-wire analytical transmitter (applicable to pH, ORP, conductivity, oxygen, ozone and chlorine) - two communication protocols are available for 5081 series products: HART communication or FF field bus; two lines of large screen display, clear and easy to understand, respectively displaying the measured process parameters and            Performance and Application            5081 series analysis transmitter can detect the following parameters: pH, ORP, conductivity (contact conductivity sensor and circular conductivity sensor), resistivity, dissolved oxygen (ppm and ppb), total chlorine, residual chlorine and dissolved ozone. 5081 can be used with most sensors of Rosemount analytical instruments company. Please refer to the technical specifications for details.            5081 transmitter is a cast aluminum spray epoxy polyester shell, solid, all-weather, corrosion-resistant, meeting NEMA 4x and IP65 protection levels, as well as NEMA 7b explosion-proof standard.            The 5081 transmitter has two LCD displays. The first line shows the character height of 0.8 inch (20 mm), and shows the main measurement parameters, such as pH, conductivity, etc. The second line shows characters 0.3 inch (7 mm) high, showing secondary measurement parameters such as temperature, and pH if residual chlorine is detected.            There are two kinds of digital communication modes available for 5081 transmitter: HART Communication (option code - HT) and FF Fieldbus (option code - FF). AMS software (equipment management program) can be used for both communication modes. Through AMS software, with the help of personal computer or factory host, the operator can set, configure, read process variables and diagnose faults for the transmitter.            The transmitter can also be configured and calibrated with a hand-held infrared remote control or Hart 375. The effective operating range of the remote control is 6 feet (1.83 meters).            5081-p pH / ORP transmitter            5081-c contact conductivity transmitter            5081-t circular conductivity transmitter            5081-a current transmitter
