Personal/Wearable CO Detectors and Travel CO Detectors
We combined these categories together as each model can be used for all three applications:
- A personal CO detector for use in your home, car, RV, or office
- A wearable CO detector for work-related applications
- A travel-sized CO detector for use in hotels, vehicles, vacation rentals, etc.
Personal CO detectors have the obvious advantage of being small and cost-effective, making them ideal for both employers and consumers alike. Personal CO detectors come standard with alarm points preset at the factory, often based on OSHA alarm-thresholds, or they'll have the ability for user-programmable alarm points down to 5 ppm. Personal CO detectors often feature a combination of audible alarms, visual alerts, and optional vibrating alarms that are useful in areas of high-noise.
Another consideration with personal CO detectors is the need for calibration, as well as the expected lifespan of the unit. Unlike a fixed-mount CO detector for the home or office, a personal CO detector will require calibration and possibly maintenance, such as battery replacement (it’s easy to do). Some manufacturers recommend you calibrate your CO detector every six months, and that too can get expensive. Others require calibration every two-years to avoid a message being displayed on the screen. In either case, the frequency of calibration is most often left to the discretion of the user.
As far as life span goes, most personal CO detectors have a design life longer than the design life of the electrochemical sensor they use, which is only about two years. Even though the original sensor and battery may eventually wear out, the rest of the unit will likely work for many years to come. What does that mean for you? If you choose a CO detector that can be easily calibrated and serviced, like Sensorcon, you may get a lot more life out of your personal CO detector than anticipated.
Another type of personal CO detector are categorized as “disposables”. Once activated, these units run uninterrupted (they literally can not be turned off) for a predetermined length of time, which is typically 24 to 36 months. They cannot be calibrated or serviced. At the end of the 24 or 36-month period, the unit is simply disposed of.
