MonoExact DF310E

NEXT-GENERATION TOUCHSCREEN TRACE OXYGEN ANALYZER
O 2
The SERVOPRO MonoExact DF310E updates the DF-310E oxygen analyzer with connectivity to a new moisture measurement , an alternative Paramagnetic % oxygen measurement and the latest digital protocols – all in a compact , intuitive , touchscreen-navigable unit .
Designed for the IG market , the MonoExact DF310E offers operational advantages over its predecessor . Low ppb to 10,000 ppm oxygen measurements are delivered through Servomex ' s proven Coulometric sensor , while 0-25 % range O 2 measurements are available as an alternative using Paramagnetic technology .
The MonoExact DF310E also offers integration of Servomex ’ s new AquaXact 1688 moisture sensor , an external Aluminum Oxide ( Al 2O 3 ) moisture sensor probe that enables the analyzers to make two simultaneous measurements for oxygen and moisture .
Fully backwards-compatible with its forerunner , the MonoExact DF310E offers full connectivity with existing hardware wiring inputs and gas inlets , ensuring full compliance with existing standards and customer agreements .
Up to 16 relays and two analog inputs are available for automation of calibration / validation tasks and remote diagnostics . Comprehensive communications are provided using traditional 0-10 VDC , 4-20mA , RS232 and RS485 analog protocols as well as Ethernet , Modbus TCP / IP and PROFIBUS digital connectivity options .
The MonoExact DF310E is optimized for measuring trace oxygen across a range of applications including nitrogen , argon and hydrogen production , tanker transfilling , specialty gas blending and electronic gases verification .
ALSO AVAILABLE : SERVOPRO MonoExact DF150E
Designed for trace oxygen measurements in industrial applications including glove boxes , heat treating , solder reflow ovens , laboratory and industrial gas production .

AquaXact 1688

FAST , ACCURATE AND RESILIENT MOISTURE MEASUREMENT
H 2 O
The AquaXact 1688 provides a fast , accurate and resilient H 2O measurement for a wide range of gas phase process applications .
Using class-leading , ultra-thin film Aluminum Oxide sensor technology , the AquaXact measures dew point and ppm H 2O in ambient temperatures ranging from -10 o C to + 70 o C . By using a much thinner aluminum oxide layer , a better defined oxide barrier layer and unique pore geometry that makes it easier to entrap water molecules , a much more sensitive and stable performance is given in comparison to rival technologies
Housed in a weatherproof stainless steel casing , the sensor remains unaffected by condensation and liquid water , providing an accurate dew point measurement across a range from -100 o C to + 20 o C , even under extreme temperature conditions . Unlike conventional moisture sensors , the AquaXact 1688 suffers no drift , the response curve remains the same , even after several months of operation at raised temperatures .
Sensor replacement is easily accomplished with high-quality manufacturing processes ensuring highly uniform performance between sensors . This ensures sensors can be interchanged freely without the loss of measurement quality or need for recalibration .
The AquaXact functions as a standalone 4-20mA transmitter , but can also be remotely interfaced with the SERVOPRO MonoExact DF310E gas analyzer ( see above ). This enables control using MonoExact ’ s high-clarity touchscreen , alarms , relays and advanced communication protocols including RS485 , Modbus TCP / IP and PROFIBUS .
Should recalibration become necessary – usually no more than annually – the associated calibration file can be uploaded into the AquaXact transmitter using a USB memory stick .
The AquaXact is flexible across a wide range of moisture measurements , including use in air separation processes , natural gas processing and transportation , glove boxes , instrument air units , ethylene production , refining gases , medical gases , semiconductors and furnace gas / heat treating .
