The Baker Hughes Panametrics Optica Chilled Mirror Hygrometer from HMA INSTRUMENTATION simultaneously measures dew point, temperature and pressure. The analyser is equipped with programmable math functions to produce custom units. In, exp +, -, x and / functions enable derived engineering units to be displayed, recorded, and transmitted to data acquisition systems. The analyser input channel is a standard 4 to 20 mA/0 to 5 VDC input, meaning that the Optica can be connected to any type of process transmitter, and be configured to display engineering units.

The Optica software is easy to navigate. Users select readout display, strip chart, analogue output scale, digital communications, self-diagnostics, cleaning, and data logging with intuitive pull-down menus. Setup values can be saved in memory and loaded anytime, either locally or from anywhere via the Ethernet port.
