SPECTRACAP oxygen transmitter OMT355
The SPECTRACAP oxygen transmitter OMT355 measures oxygen concentration optically by analyzing the absorption of light (generated by a tunable diode laser (TDL)), and associating that data to the wavelength characteristic of the oxygen molecule. A compact probe suitable for field use, the OMT355 can be flange-mounted directly into a process without sampling or sample conditioning equipment, providing the user with realtime measurement data without sample-switching delays. Typical applications for the OMT355 include gas generation, inert-gas blanketing, fermentation and composting process monitoring. Made with a stainless steel probe, the transmitter tolerates aggressive chemicals and excessive amounts of moisture. For processes with high temperatures, elevated pressures, or excessive solids content, an optional sampling cell is available for the transmitter.

DRYCAP dewpoint transmitter DMT152
The DRYCAP dewpoint transmitter DMT152 uses a new polymer sensor technology (the manufacturer’s patented Auto-Calibration firmware) to measure dewpoint temperatures as low as –112ºF, whereas previous polymer sensors were only able to measure down to –76ºF. The sensors offer proven stability and durability, enabling them to withstand condensation and to recover from exposure to water. The transmitter itself holds up well in harsh environments that require protection against dust, dirt and splashed water. It is suitable for use in dessicant air dryers, glove boxes and other dry chamber applications, as well as for any inert gases where measuring very low water vapor content is required.
