Best Electrochemical Oxygen Gas Sensor

Kidde Hardwired Smoke & Carbon Monoxide Detector, Battery Backup, Interconnectable, LED Warning Light Indicators, 4 Pack

2-in-1 Detection - Smoke & carbon monoxide detector combo alerts you to both smoke & fire events as well as poisonous, CO gas in a single device.
24/7 Self-testing components are always checking the device to ensure it's operating as expected (not a substitute for a manual push test).
Easy installation mounting bracket included for quick installation in 4 orientations.
Photoelectric sensor detects visible fire particles associated with slow, smoldering fires, while the electrochemical sensor detects carbon monoxide.
LED warning indicators alert you to various status: green = normal operation, amber = operating error, and red = smoke, fire or carbon monoxide event.

...ient temperature from -10 ~ 50 ℃, ℃/℉ switchable.
✅【Ammonia & Temp & Humidity Meter】In a humid, warm environment, ammonia gas is produced faster.Therefore, while detecting ammonia gas, you should also keeping track of the temperature (℃/℉) and humidity..
✅【Tripod Hole for Mounting】Assembled with electrochemical cell sensor for sensitive measurement. With a tripod mount port so you can mount the meter and have it measure ammonia (NH3) Gas Density continuously, keep track of the gas changing in the same spot. Perfect ammonia air detector for poultry farms, horse stables, livestock.
✅【Rechargeable Ammonia Air Gauge】The included USB cable can be connected to the plug for charging. Built with green / red charging indicator light. Remaining power indicator, Auto / Manual power off optional to save your battery..
