(PBB), polybrominated diphenyls (PBDE). Further note that Apogee Instruments does not specifically run any analysis on our raw materials or end products for the presence of these substances, but rely on the information provided to us by our material suppliers. -
Page 4: Introduction
The immersion effect correction factor for Apogee original quantum sensors (model MQ-200 and SQ-200 series) is 1.08. The MQ-210 quantum meter is designed for underwater measurements, and already applies the immersion effect correction factor to the meter’s readings through firmware. The meter consists of a waterproof quantum sensors attached via waterproof cable to a handheld meter. -
Page 5: Sensor Models
SENSOR MODELS Apogee MQ series quantum meters covered in this manual are self-contained and come complete with handheld meter and sensor. Sensor model number and serial number are located on a label on the backside of the handheld meter. -

SPECIFICATIONS MQ-210 Calibration Uncertainty ± 5 % (see calibration Traceability below) Measurement Repeatability Less than 1 % Long-term Drift Less than 2 % per year (Non-stability) Non-linearity Less than 1 % (up to 3000 µmol m Response Time Less than 1 ms Field of View 180º... - Page 7 Spectral Response Mean spectral response of six SQ series quantum sensors (error bars represent two standard deviations above and below mean) compared to PPFD weighting function. Spectral response measurements were made at 10 nm increments across a wavelength range of 300 to 800 nm in a monochromator with an attached electric light source.
- Page 8 Cosine Response Directional, or cosine, response is defined as the measurement error at a specific angle of radiation incidence. Error for Apogee SQ series quantum sensors is approximately ± 2 % and ± 5 % at solar zenith angles of 45° and 75°, respectively. Mean cosine response of twenty-three SQ series quantum sensors (error bars represent two standard deviations above...

PFFD incident on a horizontal surface, the sensor must be level. The AL-100 accessory leveling plate is recommended for use with the MQ-210 to ensure the sensor is level when attached to a cross-arm. The bubble-level in the plate makes leveling simple and accurate. -
Page 10: Operation And Measurement
OPERATION AND MEASUREMENT MQ series quantum meters are designed with a user-friendly interface allowing quick and easy measurements. To power the meter, slide the included battery (CR2320) into the battery holder, after removing the battery door from the meter’s back panel. The positive side (designated by a “+” sign) should be facing out from the meter circuit board. Press the power button to activate the LCD display. - Page 11 (http://www.apogeeinstruments.com/ac-100-communcation-cable/). Spectral Errors and Yield Photon Flux Measurements The MQ-210 Apogee quantum meters are calibrated to measure PPFD for electric light. The sensors calibration source is T5 cool white fluorescent lamps and will read approximately 12 % low in sunlight.

Spectral Errors for PPFD and YPFD Measurements with Apogee MQ Series Quantum Meters Radiation Source (Error Calculated Relative to Sun, Clear Sky) PPFD Error [%] YPFD Error [%]...
- Page 13 The MQ-210 sensor has an immersion effect correction factor of 1.08. The immersion effect correction factor is already accounted for in the MQ-210 meter firmware so there is no need to apply the correction factor to your measurements. If you wish to use your meter to make measurements in air, simply divide the measured number by the immersion effect (1.08).

Page 14: Maintenance And Recalibration
MAINTENANCE AND RECALIBRATION Moisture or debris on the diffuser is a common cause of low readings. The sensor has a domed diffuser and housing for improved self-cleaning, but materials can accumulate on the diffuser (e.g., dust, salt deposits) and partially block the optical path. -
Page 15: Troubleshooting And Customer Support
TROUBLESHOOTING AND CUSTOMER SUPPORT Verify Functionality Pressing the power button should activate the LCD and provide a real-time PPFD reading. Direct the sensor head toward a light source and verify the PPFD reading responds. Increase and decrease the distance from the sensor to the light source to verify that the reading changes proportionally (decreasing PPFD with increasing distance and increasing PPFD with decreasing distance). - Page 16 meter and sensor head. See Apogee webpage for further details on how to extend sensor cable length: (http://www.apogeeinstruments.com/how-to-make-a-weatherproof-cable-splice/). Unit Conversion Charts Apogee MQ series quantum sensors are calibrated to measure PPFD in units of µmol m . Units other than photon flux density (e.g., energy flux density, illuminance) may be required for certain applications.
