Product Description

How do I use the device correctly for carbon monoxide detection?

Step1: Turn on the Guard-533 in a fresh air environment (e.g., a well-ventilated outdoor space) and wait for it to warm up.

Step2: Approach the CO source for detection. Detecting from a distance may cause CO to disperse, leading to unstable readings.

How to determine if the Guard-533 is operational?

1. Cigarette smoke(Light a cigarette and bring it close to the sensor)

2. Burning candle (Cover the candle with a glass to make the flame smaller but not extinguish it)

Why can’t carbon monoxide be detected even when there is a combustion source present?

Not all combustion produces CO gas, only incomplete combustion does, which is characterized by a red/yellow flame in most cases. Also, ensure proximity during measurement to prevent gas dispersion, which may lead to undetectable concentrations.
