Twin glass flow tubes give a large, immediately readable display of oxygen and nitrous oxide delivery, while a single flow knob and mixture dial let the operator adjust percentage and total flow without losing the setting on the other. An oxygen flush bar delivers up to 90 L\/min on demand, and the O₂-piloted fail-safe stops nitrous oxide delivery the moment oxygen pressure is lost. This unit is supplied on a rolling five-caster mobile stand with a scavenger interface block and vacuum gauge, so it can be moved between operatories rather than committed to a single wall mount. \u003cstrong\u003eThe rubber goods are included\u003c\/strong\u003e — nasal hood, breathing bag and corrugated breathing\/scavenger circuit tubing ship with the unit, along with the nitrous oxide and oxygen DISS supply hoses, all shown in the listing photographs. Professionally refurbished by ABC Dentalworks, the flowmeter was inspected across the flow tubes and floats, mixture and flow controls, oxygen flush, fail-safe circuit, DISS inlet fittings, scavenger block, and stand hardware before listing.\u003c\/p\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:15px;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eMDS Matrx (Matrx Medical \/ Porter Instrument)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eMDM (Monitored Dial Mixer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eSerial Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e311-44 (data plate photographed in the listing gallery)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eEquipment Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eNitrous Oxide \/ Oxygen Conscious Sedation Flowmeter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eMobile Stand — Five-Caster Rolling Base\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eRubber Goods\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eIncluded — Nasal Hood, Breathing Bag and Corrugated Circuit Tubing (as shown)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eDisplay\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eDual Analog Glass Flow Tubes (N₂O and O₂)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eOxygen Flow Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e1–10 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eNitrous Oxide Flow Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e0–10 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eOxygen Flush\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eUp to 90 L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:38%;padding:10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eMinimum Oxygen Delivery\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px;border-bottom:1px solid #e5e5e5;\"\u003eFail-safe limited per MDM configuration — US units are factory set at 30% O₂;
