• Internationally compatible (100-240V) power supply / charger
• A – double orange connector (1/16 ID tubing) – useful if you choose to inject sample gas into the inlet of the analyzer using the supplied 60 cc syringe.
• B – Two particulate filters – These leur-fit filters can be attached to the inlet fitting of the analyzer to provide extra protection from particulates.
• C – T style connector – This fitting is useful as a flow limiter – by passing your sample gas through this fitting, and leaving one of the T stems open, you can reduce the flow reaching the analyzer.
• D – Inlet fitting (accepts 1/4in ID tubing) – This is a replacement spare for the inlet fitting in the event that your original fitting is damaged or the threads stripped.
• E – Adjusting screwdriver for potentiometers – This screwdriver fits the potentiometers on the back of the analyzer.
• F – Rubber Washers – These are replacement rubber washers. One is already installed behind the inlet fitting to provide a leaktight seal.
• G – 60 cc syringe for sample injection – Useful for syringe injection. Note, however that this method may require at least 120 cc of gas to get a proper reading.
• H – 1/16 ID tubing – This tubing can be attached to one of the orange hubbed needles, and affixed to the inlet fitting.
• I – Internal inline moisture trap filter (PTFE .45 micron) – This filter is a replacement for the inside particulate and moisture filter in the analyzer. Should you accidentally allow moisture into your gas flow, then find the readings not to change as expected, then you may need to replace this filter inside the analyzer by removing the top cover. This is a four layer filter which will completely block gas flow upon saturation.

Optional Items:

• Internal Pump – A mini diaphram pump installed inside the analyzer, and draws approximately 5 cc per second. Great for situations where there is no source of flow. Expected -pump lifetime is 8-10 years.
• Analog Output (vdc) – Terminal strip is provided on the back of analyzer to attach to your own data acquisition equipment. The concentration measured is proportional to the analog output, and can be modified to fit your system with a full scale of 0-1vdc, 0-5 vdc, or 0-10vdc.
• Analog Output (4-20mA) – Similar to the vdc output, we can provide a current output with a linear signal proportional to concentration. This option is useful for very long cable runs, as a break in the cable will be detected by your data collection equipment.
• Two Mode (Continuous) Pump Switch – Enables use of the pump in two modes – one mode is clicked “”on”” and leaves the pump running until unclicked. Pressing the switch lightly enables operation according to the user adjustable potentiometer timer.
• Cycling Pump – An internal circuit control allows you to program the pump to operate for x sec/min/hr and then rest for y sec/min/hr. This is especially useful for long term experiments where you do not want the pump to operate continuously, but want a fresh sample drawn in occasionally. We set it at the factory, but you can change it later. Most customers choose roughly 5 minutes on, and 55 minutes off, to run experiments over the course of days.
• Data Logger – Our data logger includes everything you need for collecting analysis data from our benchtop analyzers. For analyzers with a vdc analog output installed, the data logger is used to collect measurements for offloading to a PC or Mac.
• 
• Internal Rechargeable Battery
• Fine .01% Resolution – An extra digit of resolution can be provided for applications where accuracy is of the utmost importance. Please note that for 0-20% CO2 analysis range, we can provide this at no additional charge.
• Recirculating Exhaust – Connectible 1/8in leur fit outlet at exhaust port enables re-capture of gas for closed systems.
• Swagelok Inlet – Installed brass Swaglok inlet fitting for compatibility with your existing equipment.”
