Autopilot Desktop CO2 Monitor & Data Logger

Track CO2, Humidity, and Temperature With a 7-Day Memory Chart and Trend Display

Knowing that CO2 is being enriched is not the same as knowing that enrichment is working. The Autopilot APCEM2 Desktop CO2 Monitor goes beyond a simple ppm display — it logs CO2, relative humidity, and temperature over time, displaying the data as a digital memory chart on the device screen.

The Trend Chart feature adds a visual representation of how environmental conditions are moving, allowing you to see patterns — whether CO2 peaks correctly after lights-on, whether humidity drops through the night, or whether temperature is cycling as expected — without relying on a connected computer or separate data logger.

The APCEM2 is a monitor only, not a controller. It measures and logs but does not trigger enrichment or exhaust equipment. Use it to verify that a CO2 controller and generator system is performing correctly, or to establish baseline environmental data before dialing in controls.

Key Features & Benefits

• Monitors CO2, relative humidity, and temperature — three-in-one environmental monitoring in a compact desktop unit.
• 24-hour or 7-day memory chart — records all three parameters over an adjustable period and displays logged data on the built-in screen.
• Trend Chart display — a unique visualization that shows the direction and rate of change in environmental conditions — not just the current reading.
• Desktop form factor — compact, standalone unit that sits on a table or shelf without requiring wall mounting or cable routing to a remote probe.
• Monitor only — not a controller — measures and logs CO2, RH, and temperature but does not control enrichment or exhaust equipment.
• Affordable CO2 verification tool — provides a cost-effective way to verify CO2 enrichment performance or audit environmental conditions in a growing space.

Who Should Use the Autopilot APCEM2 Desktop CO2 Monitor

Growers who want to monitor and log CO2, humidity, and temperature over time in the grow room — whether to verify that a CO2 controller system is performing correctly, to audit environmental conditions, or to track patterns across the grow cycle.

Difference Between the APCEM2 and the APC8200 / APC8400

The APCEM2 is a monitor and data logger only — it does not control any equipment. The APC8200 and APC8400 are CO2 controllers that trigger generators and exhaust fans to actively maintain CO2 setpoints. Use the APCEM2 alongside a controller to verify performance, or in spaces where you want to understand the environment before adding active control.

Frequently Asked Questions

Can the APCEM2 control a CO2 generator?

No — the APCEM2 is a monitor and data logger only. It measures and records CO2, humidity, and temperature but does not have a control output. Use the APC8200 or APC8400 to control CO2 enrichment equipment.

What does the Trend Chart display show?

The Trend Chart visualizes the direction and rate of change for the monitored parameters over the selected time period, helping you identify trends, cycles, and anomalies without having to manually interpret raw logged data.

How long does the memory chart record data?

The memory chart records over an adjustable period — either 24 hours or 7 days. The period can be adjusted on the device to match the duration you want to review.

Can I export the logged data from the APCEM2 to a computer?

The APCEM2 displays logged data on its built-in screen as a memory chart. Check the current product manual for any data export or connectivity features, as these may vary by firmware version.
