CO2 / Temperature / Ventilation Monitor with Data Logger This is an easy-to-use CO2, temperature and ventilation rate monitor designed for use in residential or commercial applications. It has the ability to display CO2 in less than 60 seconds and can calculate and display the CFM/person ventilation rate in any building. The unit is the perfect tool for determining if air quality complaints are due to insufficient ventilation or identifying energy saving opportunities in over-ventilated spaces. The unit adds Data Logging and RH sensing to the unit which give you the ability monitor CO2, temperature and relative humidity over time and graph the data on your computer. Air Flow / IAQ / HVAC SPECIFICATIONS for Data Logger Temperature (internal sensor) Range Range for internal sensor when used outside of case Accuracy CO2 Data Logging range Resolution Response time still in air -4°F to + 158°F (-20°C to +70°C) -40°F to + 248°F (-40°C to +120°C) ±1.27°F (±0.7°C) at +70°F 0-2,500 PPM 0.7°F (0.4°C) at +70°F 15min. typical with sensor inside case; 1min. typical with sensor outside case Relative Humidity (user-replaceable RH sensor) Range 25% to 95%RH at +80°F for intervals of ≥ 10 seconds, non-condensing and non-fogging Accuracy ±5% Response time 10 min. typical in air Sensor Operating +41°F to +122°F (+5°C to +50°C) non-condensing Environment and non-fogging External input Wide range of temperature sensors (TMCx-Hx series); (accepts the following sensors) Split-core CTs for AC current (5 models); 4-20mA input cable; 0-2.5VDC input cable - accuracy ±10mV ±1% of reading, resolution 10mV (8-bit) • Patented dual beam, Absorption Infrared™ CO2 gas sensor ensures long term stability and durability • Large, easy-to-read display shows CO2 in ppm (parts per million), temperature in °F or °C, and the ventilation rate in cfm/person (cubic feet per minute per person) • Altitude compensation and manual calibration using on-board push button controls • Available with Data Logging kit which runs for 12 months on lithium battery • 4 channel logger measures temperature, RH, 2 external channels, 8-bit resolution • Capacity: 7943 measurements total • User-selectable sampling interval: 0.5 seconds to 9 hours, recording times up to 1 year • Nonvolatile EEPROM memory retains data even if battery fails • User-replaceable battery last 1 year • Size/Weight: 2.4 x 1.9 x 0.8" approx. 1 oz. PC Graphing Software (includes cable) • Launch and retrieve the data logger and graph the recorded data • System Requirements - 386 or better processor with at least 4M of RAM running Windows® 3.1x or Windows® 95/98/NT/2000/ME, with at least one available serial port • Export data files to Microsoft Excel, Lotus 1-2-3 or any ASCII-compatible program RH/Temperature Data Logging Kit • Comes with everything you need to record and graph relative humidity and temperature, as well as a custom cable that connects the unit to the Hobo® data logger • The Mini Datalogger has RH and temperature sensors build in and two external channels that accept V or mA signals • The kit comes with deluxe software for launching and retrieving the data logger and graphing the data. Data can easily be exported to to other spread sheet programs like MS Excel.The Data Logging kit is typically used with the unit but can also function as a stand alone product SPECIFICATIONS for Datalogger Meter Specifications Measurement Range (LCD Display) Measurement Range (voltage output) Accuracy Repeatability Maximum Allowable Drift in (1) Year Response Time Output Analog Output Impedance Warm-up Period (@Room Temp.)
