The LPM incorporates a built-in heater ensuring reliability and accuracy when operating in extremely cold environments. The intelligence of the electronics allows it to compensate against the influence of dirt and temperature, and optical components are protected against environmental influence, together, all these smarts allow for accurate and reliable precipitation measurements.

The quality of the optical components allows the measurement of particle sizes from 0.16mm to 7mm; particle velocity of 0.2 to 20 metres per second. The main advantages of an LPM, they are rugged and nearly maintenance free.

The LPM is manufactured in Germany and is well designed and Engineered.  The cost is commensurate with the engineering and we recommend this instrument is selected at sites where mains power is readily available, and for projects where the sophisticated nature of the data collected is required.
