Easy-to-use Extech CO240 Air Quality Meter measures Carbon Dioxide (CO2), Air Temperature, and Humidity. It also calculates Dew Point and Wet Bulb. User settable high alarm with audible beeper is perfect for conducting a quick check of CO2 level to help adjust the environmental conditions in an enclosed area, such as a greenhouse or nursery, to ensure optimal plant grown. It’s also convenient for testing the air quality in buildings such as factories, hospitals, conference rooms, schools, and anywhere that high levels of carbon dioxide are generated, to ensure proper air ventilation.

Extech CO240 Features

• Dual display of Carbon Dioxide (CO₂) concentrations and Relative Humidity, Temperature, Dew Point, or Wet Bulb
• Maintenance free NDIR (non-dispersive infrared) CO₂ sensor
• Audible CO₂ warning alarm when concentration level exceeds high user set point
• Min/Max CO₂ value recall function
• Includes software and cable for on-line (real-time) datalogging to a PC
• Automatic Baseline Calibration function
• Data Hold, Auto Power Off (with disable), Low battery indicator
• Tripod mount (tripod sold separately)
• Complete with six AAA batteries, USB cable, PC software, and soft case

Maintenance

a Do not use the meter in an environment with severe change; do not store the unit in an environment with high temperature, high humidity, and high vibration. Take the battery off if the meter has not been used for a long period of time. The Diode temperature probe is used to measure temperature and the capacitive humidity sensor is used to measure take humidity. The thermocouple and humidity sensor will start aging under the influence of oxidation, reduction, corrosion, pollution, vaporization, diffusion or other metallurgy. The aging process will affect its precision seriously. Cleaning and inspection of temperature probe: The smoke, coal, dust, grease attached on the protective tube of temperature probe will slow down the heat conduction of the thermocouple and cause measuring error. Therefore, it should be cleaned periodically. The metal coating of thin thermocouple should be replaced properly upon the occurrence of corrosion.

Cleaning and inspection of humidity sensor: The smoke and dust attached on the humidity sensor will slow down the function of humidity sensor and cause measuring error. Therefore, it should be cleaned periodically. Blow off the dust with mild compressed air instead of water or alcohol. The aluminum plate inside the humidity sensor should be replaced upon the occurrence of corrosion

REED GD-3300 Specifications

What’s included with the REED GD-3300

• GD-3300 Combustible Gas Detector
• Batteries
• Earphone Jack (for noisy environments)

 Replacing the Batteries

Replace your 1.5 volt /size R14C(B) alkaline batteries when: • The green READY light off • No light or other activity occurs upon turning the instrument on To replace the batteries: 1. Lay the instrument face-down on a back face. 2.Remove the battery cover. Apply upward pressure to the tab at the bottom of the battery cover while lifting it out. 3.Remove the batteries using a coin or screwdriver, if necessary, to pry them out. 4.Replace all three batteries with new ones.

Replacing the Sensor

Although the sensor is designed to offer many years of reliable service, it may become inoperable if it is submerged in liquid or otherwise physically damaged. To replace sensor: 1. Turn the instrument off 2.Remove the upper tip guard by pressing straight up from the alignment notch that separates the two halves of the tip guard. 3. This is a sturdy component, but use caution bending its leads. 4. Pull the sensor straight up from its tip housing. 5.Replace the sensor, pressing it straight in. 6.Reassemble in reverse order.

Operating instructions
This Reed SD-9901 Air Quality Datalogger are able to operate with three probes plugged in simultaneously. These probes are: the Humidity, CO2, and either the O2 or the CO Probe. During the operations the meter will datalog all three values and will display on the meter’s LCD only one at a time. To start using the meter plug in the Humidity, CO2, and either the O2 or the CO Probe into the sockets. Turn on the meter by pressing the Power Button. To turn the meter off, hold the Power Button for over 2 seconds. Press the Function Button to scroll through the measuring functions:

• rH: Humidity/Temperature
• dP: Dew point Temperature
• _ET: Wet bulb Temperature
• CO: CO/Temperature
• O2: O2/Temperature
• CO2: CO2/Temperature

The selected measurement function will be saved as the default.

How to use Data hold function
During the measurements, the Reed SD-9901 Air Quality Detector are able to hold on the screen the measured value. For using that, just press the Hold Button once and a HOLD symbol will appear on the Display. Press the Hold Button once again will release the data hold function.

How to use Data Record (Max., Min. reading)
The data record function records the maximum and minimum readings. Press the REC Button once to start the Data Record function and a “REC” symbol will appear on the display. With the “REC” symbol on the display. Press the REC Button once, and a ”REC. MAX.” symbol along with the maximum value will appear on the display. Press the REC Button again, and a “REC. MIN.” symbol along with the minimum value will appear on the display. To delete the minimum value, press the Hold Button once, and the display will show a “REC.” symbol only and execute the memory function continuously.
