Manufacturer: ROTRONIC Brand: Rotronic Model: 1600.CP11

The CP11 handheld instrument is the latest development of an inexpensive multimeter that simultaneously measures and records CO2, humidity and temperature. It also calculates the dew point and wet bulb temperature. Equipped with the field-tested ROTRONIC HYGROMER IN-1 humidity sensor, this instrument offers unbeatable value for money. Using the ROTRONIC HW4-Light software that comes with the device, it can be set as required and data can be downloaded, saved and analyzed.

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.

THE SERIES CDTV CARBON DIOXIDE / VOLATILE ORGANIC COMPOUND (VOC) TRANSMITTER reduces energy cost in buildings by lowering the amount of conditioned air based on the occupancy of the space. By sensing both CO2 and VOC, the transmitter can detect fumes that may need to be exhausted during lower occupancy periods.

Testo No high upgrade module sensor for flue gas analyzer. 0 to 3000 ppm. 1 ppm resolution.

Manufacturer: Sper Scientific Brand: Sper Scientific Model: 800053

Formaldehyde (HCHO) is a volatile organic compound (VOC) and common source of indoor air pollution in homes and industries due to the presence of paints, dyes, synthetic resins, textiles, cleaning agents, flooring, wall paper and in paper manufacture, construction, pharmaceuticals, textiles, horticulture and the food, medical and cosmetic industries. Meters display HCHO levels on a backlit LCD. Also read RH (relative humidity) and temperature in °F or °C which can be adjusted to any standard. Recall the maximum and minimum HCHO readings and have user selectable audible & visible alarms for maximum HCHO level. Automatically calculate 8 hour time-weighted average (TWA), 1-hour average, and 15 minute short-term exposure limit (STEL). Feature one-button calibration to fresh air, hold function and a low battery indicator. Comes complete with tripod screw, soft carrying case, 4 x AAA batteries. Records up to 32,000 data points of HCHO, temperature, and RH that can be downloaded using a USB cable and software, included with this model. Model 800053 also reads mg/m3 (in addition to ppm) and comes with an AC adaptor.
