The new measuring device 11325 is designed for use in large offices, meeting rooms, conference rooms, teachers' lounges, classrooms, or anywhere there are many people in one room.

The CO2 sensor is an NDIR sensor, also known as a non-dispersive infrared sensor.

The device features a large display with backlighting and a very easy-to-read measurement display.

The measurement range for CO2 is up to 5000 ppm.

The accuracy is precise NDIR sensor technology capable of detecting as little as 1 ppm.

CO2 levels are displayed in color with smileys:

• Green: from 0 to 600 ppm
• Yellow: from 601 to 1000 ppm
• Orange: from 1001 to 1500 ppm
• Red: over 1500 ppm

The device is suitable for rooms up to 50 sqm or 75 sqm and can be easily placed on a table.

Average values for the CO2 concentration over the last 24 hours can be displayed.

Additionally, air and room temperature as well as the time are shown.

An optional adjustable alarm provides an acoustic signal when the reference value is reached, indicating an elevated CO2 level.

Power is supplied by a rechargeable battery, allowing for wireless operation of approximately 4-5 hours.

A power adapter (DC 5.0V 500mA) and a USB cable (1.5 m) are included, enabling continuous operation via power cable.
