(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
(soil, vegetation, water, snow) temperature measurement in energy balance studies. Apogee Instruments MI series infrared meters consist of a handheld meter and a dedicated infrared radiometer, which includes a thermopile detector, germanium filter, precision thermistor (for detector reference temperature measurement), and signal processing circuitry mounted in an anodized aluminum housing. -
Page 5: Sensor Models
SENSOR MODELS Apogee MI series infrared meters covered in this manual are self-contained and come complete with handheld meter, sensor, and radiation shield. Sensor model number and serial number are located on a label on the backside of the handheld meter. -
Page 6: Specifications
Calibration Traceability Apogee MI series infrared temperature meters are calibrated to the temperature of a custom blackbody cone held at multiple fixed temperatures over a range of radiometer (detector/sensor body) temperatures. The temperature of the blackbody cone is measured with replicate precision thermistors thermally bonded to the cone surface. The precision thermistors are calibrated for absolute temperature measurement against a platinum resistance thermometer (PRT) in a constant temperature bath. -
Page 7: Deployment And Installation
The green cap can be used as a protective covering for the sensor, when it is not in use. An Apogee Instruments model AM-210 mounting bracket is recommended for mounting the sensor to a cross arm or pole. - Page 8 (distance and angle combinations) produce different target shapes and areas, as shown below. A simple FOV calculator for determining target dimensions based on infrared radiometer model, mounting height, and mounting angle, is available on the Apogee website: http://www.apogeeinstruments.com/using-your-apogee-instruments-...

Page 9: Operation And Measurement
OPERATION AND MEASUREMENT MI series infrared temperature 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 10 (http://www.apogeeinstruments.com/ac-100-communcation-cable/). Sensor Calibration Apogee MI series infrared temperature meters are calibrated in a temperature controlled chamber that houses a custom-built blackbody cone (target) for the radiation source. During calibration, infrared radiometers (detectors) are held in a fixture at the opening of the blackbody cone, but are thermally insulated from the cone. Detector and target temperature are controlled independently.

Page 12: Maintenance And Recalibration
Use only gentle pressure when cleaning the filter with a cotton swab, to avoid scratching the outer surface. The solvent should be allowed to do the cleaning, not mechanical force. It is recommended that infrared radiometers be recalibrated every two years. See the Apogee webpage for details regarding return of sensors for recalibration (http://www.apogeeinstruments.com/tech-support-recalibration-repairs/). -
Page 13: Troubleshooting And Customer Support
Error codes will appear in place of the real-time reading on the LCD display and will continue to flash until the problem is corrected. Contact Apogee if the following fixes do not rectify the problem. Err 1: battery voltage out of range. Fix: replace CR2320 battery and perform master reset. - Page 14 See Apogee webpage for further details on how to extend sensor cable length: (http://www.apogeeinstruments.com/how- to-make-a-weatherproof-cable-splice/).
