Notes: (a) |
Calibrated at 1.07μm and 10.6μm. For other wavelengths in the range 0.8 – 2μm, the calibration error may be up to ±2% more. |
Notes: (b) |
When scatter shield is installed, use the NIRS setting to compensate for slightly higher reading. When not installed, use the NIR setting. |
Notes: (c) |
For circular beam centered within ¼ of beam diameter. IMPROPERLY CENTERED BEAM CAN CAUSE DAMAGE TO SENSOR. Maximum tilt angle ±5 degrees. For rectangular beam please consult Ophir representative. |
Notes: (d) |
Water temperature range 18-30ºC. Water temperature rate of change <1ºC/min. The recommended flow rate can be lowered proportionately at lower than full power but should not be below 3 liter/min. The response time will be optimum at near 12 liter/min flow rate. For solutions for prolonged usage with untreated water (tap water, non DI water), please contact Ophir. |
