| What's new 27/4/2004 | :The picture of the controller is replaced. |
| 2002 is the first year of ventilation's control！ |
| CO2 Controller is ready to be provieded. |
| Retainment of 'comfortableness', 'healthiness', and 'energy-saving' and realization of 24-hour ventilation are simultaneously achieved with this monitor. |
| *the size of the monitor |

| Proper control of ventilation | |||
| Surplus ventilation | |||
| Insufficient ventilation |
| Proper ventilation can be realized by control with CO2 Controller. |
| CO2 Controller to be provided is the world's first controller that satisifies the following three necessary conditions of proper control of ventilation: |
| 1.Highly precise measurement of an absolute value of CO2 density in the air |
| 2.Maintenance free |
| 3.Reasonable price |
| CO2 Monitor | |
| This is a monitor to measure CO2 density in the air in a room. | |
 | The four strong points of CO2 Monitor 1．Low-cost: 1/10 of traditional ones 2．High-precision: more highly precise than traditional ones 3．Maintenance free 4．CO2 Controller only with voltage-output of a density value can be provided at a reasonable price. |
| The makers that have developed the same kind of monitor: Texas Instruments（USA） Vaisala（Finland） | |
| For more information, please contact PPM Laboratory. (e-mail: Hasebe2000@aol.com) | |
