CO2-100 Portable Air Quality Meter — CO2, Temperature & Humidity

A portable 3-in-1 meter giving instant CO2, temperature and humidity readings — essential for growers running CO2 supplementation to verify their controllers are actually hitting target levels. Built-in alarm warns against dangerous CO2 concentrations. Designed for industrial air-quality compliance as well as grow rooms.

Why growers need a CO2 meter:

• Verifies your CO2 controller is working — without independent verification you're trusting the controller's internal sensor
• Reads CO2, temperature and humidity together — three critical grow-room parameters in one portable unit
• Built-in dangerous-level alarm — safety feature that prevents accidental over-supplementation
• Low drift portable design — maintains accuracy over time without constant calibration
• Works in grow rooms, offices, workshops — industrial-grade air quality meter, not a toy
• Essential for anyone running CO2 generators or regulators — confirms you're actually getting the ppm levels you're paying to achieve

Who it's not for:

If you're not running CO2 supplementation, temperature and humidity alone can be measured more cheaply with a basic hygrometer. Not a replacement for CO2 safety protocols — if you're in a sealed room with a burner or large CO2 bottle, proper ventilation planning matters more than any meter.
