Choose based on power supply and deployment scenario:

• CMI-02 (Standard) — permanent installation with AC power (86–264 V), ambient up to 40°C. The most widely deployed model.
• CMI-02-S (Silent) — same as Standard but optimised for quieter, climate-controlled environments (max 32°C). Fewer reagent measurements per fill (250).
• CMI-02-E (Low Energy / Eco) — runs on 12 V DC: solar panels, batteries, or vehicle power. Ideal for remote sites or off-grid deployments.
• CMI-02-M (Mobile / ERU) — rack-mounted Emergency Response Unit with 10-fold multisampler, battery, and all consumables integrated. Deployable in vehicles or boats for crisis response.
