In today's review we’ll represent a model of Nighthawk Carbon Monoxide Detectors made in China from Longhorn. This model has an LCD screen which shows the concentration levels of CO. The Longhorn Carbon Monoxide Detectors are powered by 3 AA batteries with a voltage of 1.5V. This lets you use the detector everywhere – in the car, in the caravan or in the office because it does not need to be plug in. If the appliance is in a Standby mode, the green indicator lights up every 30 seconds. If the battery is low, the green indicator starts blinking continuously and you will see the warning Lb (low battery). If the concentration of Carbon Monoxide rises more than 50 ppm, the red indicator starts blinking. If the room is not ventilated within 60 minutes, the sound signal is activated. The appliance has an Electrochemical Sensor that can be tested, so in case of damage it is shown an error message (Err). The Electrochemical Sensor in this model of Nighthawk Carbon Monoxide Detectors has a 2-3-year lifespan.
