The Apogee MQ-510 is a brand new PAR meters which is specifically targeted at measuring light in underwater environments. Apogee has been giving the marine aquarium hobby a lot of attention this year with constant refinements to their handheld PAR meters.
First we had theApogee MQ-500 PAR meterwith improved sensitivity to the blue end of the lighting spectrum. The new MQ-500 PAR and the SQ-200 PAR sensor definitely gave more accurate measurements of light intensity underwater, especially with our newfangled blue heavy LED lighting.
But in testing soon thereafter Apogee realized that an immersion effect led to the sensors not recording as much PAR underwater as it should, and they issued acorrection factorfor this discrepancy. Realizing the critical value of PAR measurements in the aquarium hobby, Apogee’s work has culminated in new PAR measuring devices specifically for the aquarium hobby, the MQ-510 meter and MQ-210 Meter.
MQ-510使用与MQ-500相同的传感器,其灵敏度为389至692nm,但具有校正因子来解释直接在软件中构建的浸入效应。MQ-210米还具有内置的浸入式校正,但它使用了较旧的传感器,其光谱灵敏度为410至655nm。这使得Apogee MQ-210slightly less sensitive to blue light but it costs $100 less than the $495MQ-510 PAR Meter.
