Drive DeVilbiss Check and Go Oxygen Analyzer

The Drive DeVilbiss Check and Go® Oxygen Analyzer (Model 18580) is a highly reliable, pocket-sized diagnostic tool designed for quick and accurate verification of oxygen purity levels. Engineered primarily for medical technicians, respiratory therapists, and durable medical equipment (DME) providers, this device provides instant spot-checks of the oxygen concentration output from residential or portable oxygen concentrators and clinical gas systems.

Weighing an ultra-lightweight 3 ounces (85 grams), the Check and Go® utilizes a medical-grade Galvanic Max-250 internal oxygen sensor. This sensor delivers an impressive 15-second response time with $\pm$1% full-scale accuracy, requiring absolutely zero warm-up time. The unit is completely maintenance-free and features a single-button calibration system. To maximize operational longevity, the analyzer is driven by an internal, factory-sealed lithium battery that provides up to 1,850 hours of active testing time, backed by an automated 80-second power-down mode when it's not in use.

Design & Functional Features

• Galvanic Max-250 Sensor Integration: Features a highly stable internal sensor matrix designed for exceptional linear accuracy across a broad 0.0% to 99.9% oxygen purity range.

   

   

• Maintenance-Free Operating State: Built as a completely sealed, specialized diagnostic instrument that eliminates the need for sensor replacements or internal cell cleaning.

   

   

• High-Efficiency Microprocessor Sleep Mode: Automatically powers down the 3-digit LCD window after 80 seconds of non-use, stretching the factory-sealed power cell's lifespan up to 24 months under normal usage conditions.

   

   

• One-Touch Ambient Air Calibration: Allows you to calibrate the device instantly to room air (21.0% O2) with a single button press before testing machinery.

   

Product Specifications & Identification

Important Product Characteristics

• Clinical Spot-Check Optimization: This analyzer is engineered explicitly for rapid spot-checking and equipment validation. Because it is a completely sealed device with an internal, non-replaceable battery and sensor, the entire device is considered disposable once the sensor or battery drops below cell thresholds after extended field use.

   

   

• Environmental Operating Guidelines: For optimal accuracy, calibration and sampling must be performed within standard temperature parameters between 60°F and 104°F (15°C to 40°C). Dramatic shifts in relative humidity or barometric pressure can alter real-time sensor readings.

   

   

• Application Notice: Do not expose the internal chamber to fluid backflow or high-pressure lines exceeding 3 PSIG. The 18580 is intended only for validating medical gas delivery devices and is not an in-line, continuous-monitoring life support alarm.
