Standard Configuration
7-inch touchscreen with USB export, event audit trail and user permissions. Includes variable-speed refrigeration, antifog glass inner door, mechanical lock, embedded printer, USB, RS-232 and RS-485, two side validation ports (30 mm inside diameter) and condensate recovery. Adjustable circulation airflow and multilevel passwords are included.Humidity control and one shelf-lighting module including one light source are standard. Additional follower sources and maximum lighting positions vary by model; refer to the configuration table. Humidification uses surface evaporation outside the working chamber.
Optional Accessories
Near-UV module is optional: listed 0–2 W/m², 320–400 nm; it is not a germicidal-UV claim. Additional light sources follow the control module and have no independent display or printing. Extra shelves, software, remote messaging and qualification documents require quotation confirmation. No regulatory certification is assured. Confirm the selected modules and combined operating conditions. Power for simultaneous light and UV is not specified.
