当Biotek Marine宣布其独特的BTM3000 PAR计时，他们确实引起了很多关注。BTM 3000实际上是一个带有USB连接的裸露PAR传感器，可以通过任何常规的旧计算机，PC或Mac“供电”，并且对硬件的执行方式我们再也不会给我们留下深刻的印象。
Users ofApogee仪器par仪表will be immediately familiar with the look and feel of the BTM 3000 which ismade by Apogee exclusively for BioTek Marine。BTM 3000的传感器侧有一些自定义电子设备，以使其成为USB供电，而15英尺长的USB线确实有助于在将传感器束缚在固定机器上时移动传感器，并且它将能够在储罐中，比标准的脱水仪深得多。
BTM 3000的软件端仅花了一段时间才能达到1.0版本，尤其是对于Mac平台而言，但是现在拥有BTM 3000确实是一个值得推荐和广泛部署的工具。我们仍然对在计算机上使用BTM 3000的毫不费力，我们仍然给我们留下了深刻的印象，因为附近的应用程序瞬间识别了PAR传感器，并且在使硬件和软件可以一起工作时并没有麻烦。
For now the first application is really basic, offering a nice large readout of the PAR value in umols/m2/s and the only thing we wish we could change right now is the sampling rate, as the PAR measurement seems to be sampling at a rate of about 10 times per second so the value jumps around a bit when you are trying to read it. Other than that, a basic logging feature allows PAR value to be recorded over time intervals, which can be set so as to automatically take readings every 5 or ten seconds for logging around the tank, or whatever you happen to be measuring.
A nice neat little feature of the BTM 3000 is the display of PAR value in the system menu of Mac OSX, not sure how useful it is but it’s a cool treat to have true par values measured in umols showing up at the top pf our computer. But now that the hardware is done and completed, we can’t wait to see how the software application for it can be improved to help guide users to log light intensity all over their aquarium, perhaps even with the potential to create custom PAR graphs of light field, spread and intensity in any kind of aquarium.
如果你在我们好奇的照明强度reef tanks, and want to know the actual PAR value of the light in your own aquariums, buying the $195 BTM 3000 USB PAR sensor over the standalone apogee unit it a no brainer, especially for reef clubs wishing to invest in a useful tool to loan to their members. We’ve been pretty addicted to measuring actual PAR in our reef aquariums with the Apogee meter but the BTM 3000 is poised to replace it, especially as the software matures over time.
