Here’s a nifty new device. Milwaukee Instruments is responding to the growing popularity of small, hand-held photometers by releasing their own. The MINI Phosphate Photometer can measure phosphate in the 0.00 – 2.50 ppm range, with accuracy at 0.04 +/- ppm. These instruments, which retail for approximately $45, are great tools for aquarists who keep SPS corals or just want to keep their phosphates under control. This lightweight photometer measures only 3.2″ tall and 2.4″ wide, weighing roughly 2 ounces. Interestingly, the dimensions of this photometer are exactly the same as those of the Hanna Instruments Checker. Milwaukee Instruments also has an Iodine meter at the same price point, and we suspect to see several more added to their lineup in the future.
