Solo C3 CO Detector Test Gas Canister
Carbon Monoxide (CO) detectors operate by using an electrochemical cell, which is able to detect CO in the atmosphere and is set at a predetermined threshold.
The only way to correctly test a CO detector is to introduce CO safely to the sensor from the outside, demonstrating free flow from the atmosphere to the sensor.
The CO contained within the Solo C3 CO canister is at a level which poses no threat to the user when used correctly.
Solo CO is formulated for use with the Solo 330 Dispenser. This prevents dissipation of the CO, which would occur if used handheld.
