Visible across a large room. Continually monitors the primary IAQ (Indoor Air Quality) parameters: Air Temperature, RH and CO2. Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). This instrument is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of CO2 (carbon dioxide) such as offices, factories, classrooms, hospitals and hotels. Displays readings on a bright green LED display with 2½" high CO2 digits. Also indicates general CO2 levels with green (good), yellow (fair), and red (poor) LED lights. User may set a maximum CO2 audible alarm and adjust temperature and RH readings to match any standard. Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long-term accuracy, stability and reliability. Comes with an AC adaptor and will stand on a desk-top or wall mount. Dimensions: 12" × 8½" × 2" (304 × 216 × 51 mm) Weight: 2.9 lbs (1315 g).

The ChromAir badge is a colorimetric direct-read monitor that relies on the principle of diffusion to accurately determine the concentration of gas present in your environment. Most badges indicate from 1/10 to 2 times the Time-Weighted Average for an 8-hour work period. Readings on the badge indicate levels in units of ppm*hr. Dividing this value by the length of its exposure time gives your resulting concentration in ppm. The range of the Chlorine badge reads from 0.4 - 13 ppm*hr. (Sold here as a 10-pack. Morphix Part # 380004-10)

This SafeAir badge provides a low-cost visual indication when Carbon Monoxide is present in your environment. A color change, in the form of an exclamation mark, warns of the presence of the targeted chemical and allows you to take appropriate action. This particular badge is designed to indicate the presence of carbon monoxide above a threshold level of 7.0 ppm*hr. (Sold here as a 50-pack. Morphix Part # 382012-50)

Manufacturer: Dwyer Instruments, Inc. Brand: Dwyer

The Series CDX Carbon Dioxide Transmitter is a low cost and high performing CO2 sensor. This product will provide immediate energy savings by functioning in conjunction with building automation systems and allowing the user to effortlessly and effectively control fresh air into preferred areas. On-Demand ventilation using CO2 sensors prevents energy losses from over ventilation while maintaining indoor air quality. The potential for the greatest energy saving occurs in areas where occupancy alters over the duration of the day. The Series CDX Transmitters utilize the patented Automatic Background Calibration (ABC) Logic self-calibration system. ABC Logic virtually eliminates the need for manual calibration in applications where the indoor CO2 level drops to outside levels during unoccupied periods. If the transmitter is being used in an application where a building is continuously occupied 24 hours per day, then the user will permit that the ABC Logic feature be turned off.

Testo measuring instrument for ambient air conditions, for assessment of Indoor Air Quality and adjusting and testing VAC systems, stands out on account of its efficient measurement process. Probe-controlled menus and selectable user profiles, e.g. for duct measurement or long-term measurement, ensure the user-friendliest operation possible. The new IAQ probe measures Indoor Air Quality by measuring the CO2 level, air moisture and air temperature. In addition, the lux probe and comfort level probe can be connected to assess draught air. Clear analysis and archiving ensure practical PC documentation. Temperature and humidity measurement is integrated in the new thermal probe. The special flow protocol professionally documents duct measurements. It is also possible to connect additional temperature and humidity probes. Readings from up to 3 temperature or humidity probes can be clearly displayed in the measuring instrument; data transmission is by radio, i.e. wireless. Protection class IP54. Storage temperature: -22 to +158 degree F. Operating temperature: -4 to +122 degree F. Battery type: Alkali manganese, mignon, type AA. Battery life: 200 hr (typical vane measurement). Material/housing: ABS/TPE/Metal. Measures 220mm length by 74mm width by 46mm height.

Dwyer® Series CDTR Carbon Dioxide, Relative Humidity and Temperature Transmitters reduce the number of sensors mounted on a wall or in a duct. By combining CO2, RH, and temperature in one device, system integrators are able to lower installation time of mounting multiple housings, while lowering material cost at the same time. Even with the three sensors combined into a single unit, replacement cost is not increased due to the pluggable nature of the humidity sensor, which allows it or the temperature to be replaced at a fraction of the cost of a new CO2 transmitter. Like our popular Series CDT Carbon Dioxide Transmitter, a single-beam dual-wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied* and unoccupied buildings against light source aging effects. The single-beam dual-wavelength sensor technology provides the highest level of accuracy compared to Automatic Baseline Correction methods which can unintentionally shift the calibration based on CO2 levels and barometric pressure conditions. In order to achieve a higher level of accuracy, the Series CDTR also includes digital barometric pressure adjustment and the ability to field-calibrate the sensor. Universal outputs for both carbon dioxide and relative humidity allow users to select the transmitter output to be 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC to work with virtually any building management controller. Additionally, passive thermistor or RTD sensor can be ordered for a temperature output. Push buttons are standard on all configurations of the transmitters for access to the menu structure, but wall mount configurations can be ordered without the buttons.

Manufacturer: Dwyer Instruments Brand: Dwyer Model: CDD

The Model CDD Duct Mount Carbon Dioxide Transmitter monitors the occupancy in a room by detecting the concentration of carbon dioxide in the return air duct. The non-dispersive infrared sensing technology automatically updates the calibration of the transmitter using a proprietary logic feature which limits the amount of error due to drift. The Model CDD can measure up to 2000 PPM in duct air flows less than 1500 FPM.
