Overview
The imported portable carbon dioxide concentration meter uses a membrane glass electrode based on electrochemical principles and a carbon dioxide gas sensor. According to this principle, when carbon dioxide gas passes through the membrane and dissolves in the internal solution, the pH value of the solution changes.
Product Details
1、 Measurement principle
The membrane type glass electrode based on electrochemical principles uses a carbon dioxide gas sensor. According to this principle, when carbon dioxide gas passes through the membrane and dissolves in the internal solution, the pH value of the solution changes. Because the change in pH value is directly proportional to the concentration of carbon dioxide, the degree of change is measured to determine the concentration of carbon dioxide.

3、 Characteristics
1. Short term memory function: The time interval is 1 second, 99 minutes, and 59 seconds.
2. Environmental temperature/humidity: 0 to 45 degrees, not exceeding 90% (no condensation)
3. Concentration conversion function: You can switch between gas phase concentration (% (v/v)) and liquid phase concentration (milligrams/liter).
4. The memory function can save 1000 data items. Support automatic save interval*
5. Long interval memory function: 2 minutes to 99 hours. 59 minutes. When using the long-term memory function, the concentration is measured for 1 minute after the switch is turned off (entering sleep mode). It is still until the beginning of the next measurement. )
6. The interface is for external devices: the ability to connect the instrument to a personal computer, an external printer, and a tape recorder. ）We also provide special data collection software to load and save measurement data in text format to personal computers.
7. Waterproof construction (instrument part): IP 67 (with sensor connection and external I/O port shielding enabled). The part of the meter can be submerged at a depth of 1 meter for up to 30 minutes.
8. Excellent selectivity: The membrane glass electrode method is used to prevent the influence of other mixed gases (excluding acidic gases and base gases). There are also samples that do not require drying, as the sensor is relatively unaffected by humidity.
