Replacement Sensors

Did you know sensors for gas monitors have a lifespan? Gas monitors are made to last for years, but old sensors can mean false readings and faulty equipment. Luckily for you, most gas monitors have field replaceable sensors making it easy to keep your devices running. Apollo Safety has replacement sensors for the most popular single and multi-gas monitors on the market. 

Prices are subject to change without notice due to ongoing tariff adjustments and market conditions. For the most accurate and up-to-date pricing, please contact us directly.
