| BENEFITS |
| Large Display |
Allows for all variables to be displayed simultaneously
for quick, easy readings. Displays: |
- CO2 in % or PPM
- Temperature °C or °F
- Elevation in FT or M
|
| 4 AA Batteries |
Provides up to 48 hours of operation for easy
portability or use AC/DC power supply for continuous monitoring. |
| Elevation Correction |
Take the guess work out of readings ~ enter
current elevation, and the sensor automatically adjusts. |
| Quick, Easy Calibration |
No parts to lose. Just connect the gas and
make any necessary adjustments through the control bottons. |
| Attractive Case |
Small, modern design complete with a "kickstand"
for visible readings at glance. |
