tSENSE is an advanced and versatile 3-in-1 transmitter designed for installation in the air-conditioned zone. It measures CO2 concentration, temperature, and humidity in the ambient air accurately without the need for additional compensation ─ true read. The data transmits to a BMS system or a stand-alone controller using industry standard output signals and communication protocols. tSENSE combines all the necessary elements for effective climate control in commercial office buildings, hospitals, hotels, schools, and other facilities. Using CO2 monitoring for demand control ventilation (DCV) allows a healthy, comfortable, and cost-effective environment for the occupants. It is flexible in design with temperature control and a combination of humidity control optional. Though suitable for use in many different energy-efficient ventilation strategies, SenseAir® welcomes any discussions for specific needs. Complies with ASHRAE standard 189.1 (±50ppm @ 1,000ppm of measured CO2 value). Download Product PDF

Model No. 31.5008.02 For monitoring CO2 concentration in homes, offices, schools & nurseries CO2 level measurement with traffic light indicator Time, indoor temperature and humidity display Clear chart of historical values (minute, hour, day, week) Logger function saves more than 1 million records on the micro SD card   Who breathes good air is healthier, happier and can do more. School children concentration is improved with lower CO2 levels. Headaches, dizziness and permanent fatigue are often due to a high concentration of CO2 in the air. TFA’s AIRCO2ntrol 5000 monitor helps you monitor how stale and contaminated the air is in indoor spaces where many people are present such as in school classrooms, offices and public buildings. Timely and energy-efficient ventilation ensures a healthy indoor climate. The AirCO2ntrol 5000 is a CO2 monitor with data logger function via SD card. In addition to the CO2 levels, the device measures the temperature and humidity of the environment and informs you of the date and time.  The display shows the current CO2 levels as well as a graph with past values and the associated maximum and minimum values. A coloured traffic-light display allows the interpretation of the CO2 values at a glance and changes from green to yellow and to red depending on the air quality and the setting of the limit values. If a specified maximum value is exceeded, an additional warning signal may be provided if the CO2 concentration levels being too high. Specification Delivery contents CO2 meter, micro-USB cable, manual Measuring range CO2 0 ... 5000 ppm Measuring range humidity 0 ... 95 % Measuring range temperature 0 ... 50 °C Clock  Quartz clock Material Plastic Power Micro-USB Dimensions (L) 120 x (B) 33 x (H) 66 mm Weight 110g  Download Product Sheet PDF

Model No. 31.5009.02 For monitoring CO2 concentration in school rooms and nurseries CO2 level measurement with 24-hours graph Illumination colour indicates different conditions Displays the time, temperature and humidity Power supply via micro-USB cable Who breathes good air is healthier, happier and can do more. School children concentration is improved with lower CO2 levels. Headaches, dizziness and permanent fatigue are often due to a high concentration of CO2 in the air. TFA’s AIRCO2NTROL monitor helps you monitor how stale and contaminated the air is in indoor spaces where many people are present such as in school classrooms, offices and public buildings. Timely and energy-efficient ventilation ensures a healthy indoor climate. Did you know that tracking CO2 levels can help you minimize the risk of catching COVID-19? The monitor shows on the display the current CO2 content of the room air, the temperature, humidity and the time.The display’s illumination colour can be used to quickly evaluate and interpret the current CO2 readings. Depending on the setting, the illumination directly signals the current air quality in the traffic light colours (green, orange, red). Alternatively, the red display illumination can be used as an optical signal in the event of an alarm when a certain limit has been exceeded. As a further variant, you can choose a solid colour from seven shades or switch off the illumination completely.The three smiley icons serve as a comfort-level zone indicator for the measured values of the last 24 hours. If the reading is at the level of the happy smiley, the air quality is ideal to good. In addition, the graph clearly shows the CO2 levels development of the last 24 hours.The power is supplied via a suitable USB power source.
