5. PT520A Natural Gas Detector
It seems this product is an excellent, budget-friendly tool for detecting potential gas leaks in well-ventilated residential settings. The reviewer highlights its effectiveness in tracing faint gas odors, such as identifying a poorly fitted pipe union after a water heater installation and locating a leak behind an old boiler’s regulator. The meter is praised for its ability to pinpoint leaks that would otherwise be impossible to find without professional equipment.
However, it’s important to understand the product’s limitations and intended use. This is not a high-end professional detector with features like digital readouts, an air pump, or confined-space safety. Instead, it’s a qualitative tool designed for well-ventilated areas, requiring patience—users must hold it in place for about 15 seconds to allow the sensor to sample the environment. Negative reviews often stem from improper use, such as waving it around expecting instant results.
Safety is emphasized as a top priority. The reviewer strongly warns against using this meter if there’s a strong gas smell—evacuate and call professionals immediately. Tragedies, like a local school explosion, underscore the importance of leaving major leaks to experts.

Buying Guide for Best Home Gas Detectors
Types of Gas Detectors
Home gas detectors primarily monitor carbon monoxide (CO) and natural gas (methane or propane). CO detectors use electrochemical sensors for accuracy, while natural gas detectors often rely on catalytic or GSS sensors. Some models, like 4-in-1 detectors, combine both functionalities. Choose based on your needs: standalone CO detectors for homes with gas appliances, or dual detectors for comprehensive protection.
Key Features to Consider
– Sensor Technology: Electrochemical sensors (for CO) and catalytic/GSS sensors (for natural gas) offer reliable detection.
– Alarm Type: Loud audible alarms (85+ dB) are essential; visual alerts (e.g., flashing lights) add extra safety.
– Power Source: Plug-in models with backup batteries (like Kidde) ensure uninterrupted operation. Battery-powered units (e.g., PT520A) offer flexible placement.
– Durability: Look for ABS construction and humidity resistance for long-term use.
Placement and Installation
Install CO detectors near bedrooms and on every floor, avoiding kitchens or garages to reduce false alarms. Natural gas detectors should be placed near gas appliances or ceilings (gas rises). Compact, lightweight designs (like PT199) allow for versatile mounting. Follow manufacturer guidelines for optimal performance.
Maintenance and Warranty
Test detectors monthly and replace batteries annually. Sensors degrade over time; replace units every 5–7 years. A 5-year warranty (like Kidde’s) ensures long-term reliability. Some models include storage bags or boxes (e.g., PT199) for portability and protection.
Budget and Value
Prices range from $20–$100. Budget options (e.g., basic plug-in models) suit minimal needs, while premium detectors (like 4-in-1 units) offer advanced features. Balance cost with sensor accuracy, alarm volume, and warranty coverage for the best value.
Frequently Asked Questions (FAQs) for Best Home Gas Detectors
How often should I replace my gas detector?
Most detectors last 5–7 years due to sensor degradation. Check the manufacturer’s guidelines and replace if the unit fails monthly tests or the alarm sounds unexpectedly.
Can one detector monitor both CO and natural gas?
Yes, 4-in-1 combo detectors monitor both gases. However, standalone units (like Kidde’s CO detector) may offer higher accuracy for specific threats.
Where is the best place to install a natural gas detector?
Place detectors near gas appliances (e.g., stoves, furnaces) or on ceilings, as natural gas rises. Avoid enclosed spaces to ensure proper airflow for detection.
Do gas detectors work during power outages?
Battery-powered or plug-in models with backup batteries (like Kidde) remain operational. Ensure your detector has a battery backup for uninterrupted protection.
What’s the difference between electrochemical and catalytic sensors?
Electrochemical sensors (for CO) react with gas to produce an alarm. Catalytic/GSS sensors (for natural gas) detect changes in electrical resistance. Both are reliable but designed for specific gases.
