KE25F3LF electrochemical lead-free oxygen sensor for environmental control - combustible gas monitoring
Features:
Lead-free Galvani battery sensor
- Sensors operate without external power supply
- No warm-up time required
- Compliant with RoHS2 standards
* Weakly acidic electrolyte
- Almost unaffected by CO2, H2S, SO2
- Long life, 3~5 years in the air environment
Notes:
1) If two oxygen concentrations of 0% and 30% are used for calibration
If accurate, the range is 0 ~ 30% oxygen content
When KE-12F3LF and KE-25LF/KE-25F3LF
Full scale accuracy is ±1%, KE-50LF full
The accuracy is ±2%. If you use 0% and 100%
Two oxygen concentrations to calibrate the range
When the oxygen content is 0-100%, KE-25F3LFM is full
The accuracy of the range is ±1%.
2) In order to meet the response speed in the specification table, the sensor
The air exchange speed should be greater than 200 ~ 300ml/
Use under minute conditions.
3) Normal air at 20˚C (1013 hPa / 21%O2)
The life expectancy of the sensor refers to the output value falling to the beginning
The initial value is 70% of this period.
| Life expectancy at 20˚C in normal air (Note 3) | About 6 years |
| Test gas | 21% O2 |
| Atmospheric pressure | 1013hPa |
