Accessories.

All of these accessories (except the Bedfont wipes & Hand Sanitizer) are required for the use of the monitor.

1.    Flatpak Mouthpieces
Item:  FP-MP/250  |  Quantity:  250 Mouthpieces  |  $35.00
The first accessory is the cardboard disposable mouthpieces, packaged 250 per box. They are disposed of after use on each subject.  The cardboard disposable mouthpieces are manufactured and packaged under "clean room conditions" which ultimately means a cleaner, more hygienic product.

2.    D-piece Valves
Item:  D-Piece  |  Quantity:  12   |  $94.50
Item:  D-Piece-6  |  Quantity:  6   |  $48.50
The second accessory is the D-piece one-way valve sampling system, which is proven to remove and trap >99.9% of airborne bacteria.  The cardboard disposable mouthpiece hooks onto this valve and it allows for one-way breathing.  The subject can exhale through the valve but cannot inhale, which helps to keep the test hygienic.  The valve can be used multiple times on multiple subjects.  The D-piece should be replaced every 30 days or if visibly soiled.  Your monitor cannot be used without this item and you will eventually need to replace it, so it is helpful to have extra on hand.

3.    Calibration Kit
Item:  CO-Calib-34-50  |  $250.00
Kit Contents:  (1) Regulator, (1) Canister, (1) Cali-Adapter
The third required accessory is the calibration kit.

The calibration kit is a one-time purchase in the sense that the hardware that comes with the kit should last the lifetime of your monitor (assuming you take care of it).  This kit comes with a regulator and a can of gas. The can of gas should allow for approximately 17 calibrations (the can is about the size of the small fire extinguishers that most people keep under their kitchen cabinets in their home). Once the can of gas is depleted, you would simply purchase a replacement can of gas, not another calibration kit.  Your monitor will require calibration every six months, regardless of use and it will come calibrated from our facility (which will be good for six months). Calibration is a simple procedure and instructions do come with your monitor, however, complimentary coVita phone support/training on calibration is also available should you require assistance with the procedure. 
It is not necessary to purchase a separate calibration kit for every monitor, if you are purchasing more than one monitor (assuming you can get the monitors to the calibration kit).  Please speak with a coVita representative for further details.
