PRODUCT INFORMATIONLABORATORY ANALYSISCO 2 ANALYSERORBISPHERE 3658CO 2ORBISPHERE 3658 portable systemfor selective CO 2 measurement➔ Ideal for wine, lowcarbonated and fizzydrinks➔ Robust design for spotchecks in the productionplant➔ Short analysis time; idealfor measurement in smallpackages➔ No sample preparation;simple, safemeasurementsProvides accurate, selective CO 2measurementThis well balanced, robust, portableanalyser is specifically designed forthe beverage market and for use inbreweries, wineries, bottled water andsoft drink plants.Simple to use and easy to maintain,the ORBISPHERE 3658 is perfectlysuitable for laboratory analysis ormeasurement in the more demandingenvironments at line.Calibration and validation of theinstrument can be carried out quicklyand easily using the ORBISPHEREHigh Precision Calibration Kit. Thisensures that each measurement ofdissolved CO 2 gives a true readingwhich is critical to taste, foam and finalproduct quality.

ORBISPHERE 3658_CO 2 ANALYSERSimple and easy to useOperationBefore each measurement cycle theTC sensor is automatically flushedwith ambient dried air supplied by theintegrated pump and condenser. Aftereach purge, the gas to be measureddiffuses from the liquid sample throughthe membrane, changing the thermalconductivity of the gas surroundingthe detector. It is the rate of changeof the thermal conductivity thatallows the concentration of the gasto be calculated. As each gas hasits own specific thermal conductivitythe measurement is not affected bythe presence of other gases unliketraditional total pressure/temperaturemethods.The flow chamber of the ORBISPHERE3658 allows the sample to flow overthe sensor membrane. At the sametime the ambient air is dried with acondenser and used periodically toflush the TC detector both in standardmeasurement mode and in standbymode.The simple layout of the instrumentface and the inclined key boardmake the ORBISPHERE 3658 simpleand easy to use, both at line andin the laboratory. Different gas andtemperature units can be configureddepending on the application or localstandards.The chassis is made from stainlesssteel making it strong and robust,critical features for an instrumentused in harsh plant environments. It iswaterproof and corrosion protected.The large handle makes the instrumenteasy to manage even when theuser wears gloves. The robustmanufacturing allows the instrument tobe hung from process pipes for longterm diagnostic work.The ORBISPHERE 3658 inlet tube canbe connected to a sample point or to apiercing device by a simple connector,making it quick and easy to install. Theoutlet tube of the instrument allowsthe sample to be drained away. Theoutput valve controls the flow rate ofthe sample through the flow chamber;an optional flow meter is availableto set optimum response time withminimum flow for package analysis inlab applications.Benefits➔ Low maintenance; annualmembrane change and calibration➔ Easily calibrated/validated with theHigh Precision Calibration Kit➔ Accurate, repeatable measurementsat line or in the laboratory- Measures low CO 2 concentrationlevels for low carbonatedproducts and all wines.- Measurements are not affectedby the presence of other gasesunlike traditional total pressure/temperature methods.➔ Robust and compact constructionresponds to the harsh plantenvironment- Materials of construction chosento prolong product life- Measurement process hasno moving parts to minimisemaintenance frequency.➔ Optimum total cost of ownership- Simple design making themaintenance quick and easy- Fast response time; keepinganalysis time to a minimum- Requires small sample volume;minimising waste.➔ Designed for quality- Simple and traceable calibrationusing the ORBISPHERE HighPrecision Calibration Kit- Memory stores up to 500readings.- Downloads data easily on a PC foranalysis and quality traceability.www.hach-lange.com

Real time monitoringMaintenance, calibration andvalidationNo moving parts in the sensor resultsin low maintenance, typically requiringa simple sensor membrane changeannually. In a standard application it isrecommended that the instrument becalibrated once a year.To directly mimic operating conditionsa liquid calibration can be performedwith the patented High PrecisionCalibration Kit. These kits may alsobe used for periodic validation of theORBISPHERE 3658.The High Precision Calibration Kitoffers:- Traceable and accurate calibration- Safe, quick and easy solutionpreparation.High and low level kits are availableto ensure accuracy in the appropriatemeasurement range.The ORBISPHERE 3658 can be easilywiped down and the sample pathsimply cleaned by flushing the flowchamber with warm water.Communication and datamanagementThe ORBISPHERE 3658 display islarge, easy to read and can be lit upby pressing the light button on thekey board. No conversion tables areneeded as this instrument directlyindicates the gas concentration in thechosen unit. The temperature of thesample is displayed by pressing one ofthe keyboard buttons.The ORBISPHERE 3658 uses twostandard and rechargeable C type,NiMH or alkaline batteries. When it istime to change the batteries, a “LowBattery” message is shown on thedisplay.The change is quick and easy to do bysimply unscrewing the compartmentlid; there is no down time for theinstrument. Stored measurements inthe instrument memory are not lost ifbatteries go flat or are being changed.Each instrument comes with aWindows ® software package, thatenables a user to analyse the storedmeasurements and to configure theinstrument.Using the RS232 connection,stored measurements can be simplydownloaded onto a PC for analysis.This connection can also be used tosupply a DC power supply using anoptional AC/DC transformer.
