2The benefits of electronicrefrigeration system analyzersThe new analyzers from TestoTesto is again setting standards in refrigeration technology with thenew refrigeration system analyzers for measuring, recording,regulating and analyzing refrigeration systems and heat pumps.What began with accurate and practical pressure and flow velocitymeasuring instruments and electronic manifolds for the refrigerationtrade, now finds its technological continuation in the new refrigerationsystem analyzers testo 560, 556 and 530.The high-quality analyzers form a unit composed of highly accuratesensors for measuring pressure, vacuum, temperature (up to 4temperatures simultaneously), current consumption, oil pressure andrefrigerant filling quantities. The instruments have a 4-way valve blockwith stowable valve knobs (testo 556 and testo 560). The large,backlit display digitally shows the pressure and the condensation andevaporation temperatures. There are 30 refrigerant curves stored inthe instrument, which can be updated free of charge via internet andsoftware (testo 556 and testo 560). This makes the instrument familysuitable for almost all refrigeration systems,and replaces thecomplicated mechanical manifolds.Among the most important characteristics are the recording anddocumentation of the values measured on site. They can be directlystored in the instrument and later transferred to a PC. Onlinemeasurement on site via a PC is also possible.Newly developed software “EasyKool”The newly developed software “EasyKool” offers professional dataadministration on a PC, and thus optimum refrigerant management.Measurement values can be shown graphically as well as in tabularform. If all actions are recorded during commissioning, acommissioning report can be drawn up. Uninterrupteddocumentation of data over a defined period of time allows thecauses of malfunctions to be objectively diagnosed.

13Multi-purpose measuring instruments for analysing refrigeration systemstesto 435The testo 435 provides thepossibility of analysing indoor air.This serves on the one hand asan indicator of the well-being ofpeople at their workplace, and onthe other hand as an importantdeciding factor in storage andproduction processes. Indoor airquality furthermore signalizeswhether the indoor air system(VAC) is being used with optimumenergy economy, or whether itneeds to be adjusted with thehelp of testo 435. In addition toclassical probes with a wire,wireless measurement up to adistance of 20 m (withoutobstruction) is possible. Damageto the wire or hindrances inusage are thus eliminated. Amaximum of three radio probescan be recorded and displayedby testo 435. The radio probesare available for the measurementparameters temperature and,depending on the instrumenttype, humidity. The optional,easily attachable radio modulecan be retrofitted at any time.More user comfortThe testo 435 excels through itslogical use and easy-to-followmenu. For measurements atdifferent locations, testo 435-2has the advantage that thereadings are allocated to therespective measurement location.For duct and IAQ measurementapplications, the instruments canbe switched over between userprofiles.Absolutely robust instrumentconceptThe reliability of measuringinstruments is a deciding factor.The testo 435 is a robust andreliable measuring instrumentwith protection class IP 54.

Up to 4 more probesof your choice can be connected tothis logger. Additional probeconnection options are made possibleby connecting more loggers. Thefollowing features give you flexibilitywhen measuring data:• Variable program start• Adjustable measuring cycle• Number of readings• Program cancel can be definedThe measurement program can bestarted as follows:• At a certain time or date• Manually using function buttons• If certain values are exceeded orundershot• Via an event trigger socket signalThe exceeded alarm values can beevaluated for display or control via arelay.Control unitThe control unit displays themeasurement data and controls thetesto 454 measuring system. Thefollowing parameters are programmedin the control unit:• Locations• Measurement programs• Limits• Precision adjustment• System configurationEfficient operation of the measuringsystem is guaranteed by the probedependentmenu guide, for example,or the clear display of readings withnames. The control unit is connectedvia the serial interface in thelaptop/PC.Additionally the control unit has alloptions for mobile use of a hand-heldinstrument.Testo databus controllerAlternatively, the Testo databuscontroller for the laptop/PC can beused in place of the control unit forreading out and control of thedecentralised loggers. The Testodatabus controller is connected viathe USB interface of the PC/laptop.Online measurement allows thereadings from multiple loggers to bedisplayed easily and clearly on onescreen. System-relevant data andreadings are stored in the laptop/PCand in the loggers.Testo databusCommunication between controlunit/logger, Testo databus controller/logger and other boxes takes placevia the Testo databus. Using the Testodatabus, you have the option ofoperating loggers at differentlocations. Distances of up to severalhundred metres pose no problem forthe Testo databus. In combinationwith the Testo databus controller andthe software ComSoft 3, the testo454 data loggers can be validated forrequirements according to 21 CFRPart 11.Analog output boxThe logger readings are output as acurrent signal (4-20 mA signal) fordisplay units or output on an analogrecorder.Power boxThe power box is used to supplypower to the loggers, control unit,analog output box and the Testodatabus thus increasing operating lifein the field.
