• Photo is for reference only - CO2 External Probe Not Included
• Measured values: CO2, Atmospheric Pressure, Counted Values
• CO2 measurement range: 0 to 10,000 ppm
• CO2 Accuracy: 100 ppm + 5% of the measured value at 23 °C a 1 013 hPa
• Atmospheric pressure measurement range: 600 to 1100 hPa

Dataloggers are designed for the measurement of carbon dioxide concentration in a building interior. Upper and lower limits can be set for an alarm on each measurement channel. Recording can be performed continuously or at alarm time only.

Measurement and monitoring

• Temperature
• Humidity
• Dew point
• CO2
• Two-state inputs
• Counter

Mobile Data loggers measure physical quantities such as temperature, dew point, humidity and monitor also two-state signals or count pulses. The measuring interval can be set up from 1s to 24h. The measured value is shown on the LCD display as well as MIN / MAX value.

Alarm indication

• Exceeding alarm limits on the channel
• Device failure
• Battery condition
• Memory occupancy
• External power failure

For each measurement channel, you can set upper and lower limits. In case the limits are exceeded the alarm is indicated on the display, visually by LED or acoustically. Users can be also informed about device failure, battery and memory state or external power failure. The device also supports Latched alarms - every alarm occurring in the device remains active until some operator’s action, irrespective of the measurement values (until the time of manual cancel).

Record

• Non-cyclic record mode
• Cyclic record mode (FIFO)
• Recording continuously
• Recording at the alarm time

Recording can be performed continuously or at alarm time only. Measured data can be stored in memory at intervals from 1s to 24h. Logging mode can be adjusted as non-cyclic when logging stops after filling the memory or cyclic, when the oldest recorded values are overwritten by new ones after the memory is full (first in first out). Up to 500, 000 values can be stored in memory.

Data transmitting

• Simple data downloading via USB cable

The recorded data can be transferred to a personal computer via USB cable.

COMET Vision 2.0 - Analytic and Configuration Software

The recorded data can be transferred to a PC via USB cable or via GSM network for further analysis. Obtained values can be displayed in the form of a table or graph. Data and reports can be printed or exported for further processing. Comet Vision software 2.0 allows setting of device and simple data analysis. Comet database software allows collecting data from unlimited numbers of Comet devices and displaying measuring channels from unlimited number of devices on one screen. Comet cloud supports easy online access to measured data.
