- Power and maintenance: Consider battery life, ease of replacement, and whether the unit requires AC power or operates on batteries.
- Mounting and portability: Wall mounting, roof protection, or tabletop placement should align with your space and usage pattern.
- Data visibility and integration: Some models provide trend arrows or data history; others offer digital vs. analog displays. Choose based on how you prefer to interpret data.
- Durability and weather resistance: For outdoor or greenhouse use, select models with durable housings and features like protective roofs or sealed casings.
