Liter Meter 3

The LiterMeter III offers features found only on expensive laboratory pumps. Built-in calibration features eliminate the guesswork of un calibrated competitive units. Unlike noisy industrial metering pumps sold to the aquarium trades, SpectraPure's LiterMeter III was specially designed for critical aquarium dosing and is so quiet you can use it in your living room. Improved three-roller direct-motor drive eliminates noisy gears and improves flow accuracy and tubing life. It can be run dry without damage. Three independent programs control the internal pump, as well as two optional external pumps. The LM3-RPM is a LiterMeter III pump mounted in a small plastic box. The LM3-TCM is an optional level sensor that interrupts power to the LiterMeter III when a high water level is detected. The LM3-WXM combines an LM3-RPM and an LM3-TCM in one package, interrupting power only to that pump. See the Operations Manual for application examples.
