CO-Pocket™ Carbon Monoxide Detector - 2027 Version

Available at Aircraft Spruce.

• Fast visible response. After warm-up, CO-Pocket-2027 responds to CO test gas within 5 seconds. The live reading updates every second, helping you see a developing change without waiting for an alarm threshold.

  
  

• A color display with more useful information. Large CO numerals, color-coded warning levels, and an on-screen level guide replace the original black-and-white presentation. Readings appear in 1 ppm increments, including single-digit values. The display also shows battery voltage, internal temperature, and sensor communication status.

  
  

• 90 minutes of history, plus PEAK. Each history bar preserves the highest reading from one minute, so a brief increase remains visible after the current reading falls. PEAK retains the highest reading since power-on. You do not have to catch every change as it happens.

  
  

• Individually calibrated at Radiant. We establish each unit’s clean-air zero, calibrate its response with 100 ppm reference gas, and measure its temperature response in a heated chamber. The instrument automatically applies its own temperature-correction table. No user calibration is required.

  
  

• Tougher construction and simpler controls. The transparent top is paired with an extra-tough nylon bottom. A front-panel slide switch provides positive on/off control, while two buttons handle brightness, screen wake, and temporary alarm silence.

  
  

• Visible warnings, with optional powerful sound. The screen changes to yellow at CAUTION and red at ALERT. A flashing red light begins at 35 ppm. Add the optional 110 dB external alarm for repeating audible warnings at 50 ppm and above. A button press silences the sound temporarily without stopping the visual warnings or monitoring.

  
  

• The external alarm Annunciator is sold separately; the instrument has no internal beeper.

  
  

• Rechargeable, with continuous monitoring while the screen sleeps. Up to 48 hours of operation on a single charge, with automatic display sleep. Monitoring, history, and peak capture continue while the screen is dark, and a CO warning wakes the display. Recharge through USB-C using the included cable; the instrument can also operate while charging.

We calibrate each CO-Pocket-2027 ourselves before it leaves Radiant.

We check each instrument in clean air, expose it to 100 ppm reference gas, and characterize it in a temperature chamber up to 42°C. The instrument stores its individual correction data and applies them automatically during operation. This is calibration for the particular unit you receive—not simply a common adjustment applied to every sensor.

There is no pinhole adjustment or user calibration procedure. Before use, switch the instrument on in clean air and allow the full three-minute warm-up to finish.
