Megger PVM210-IRRADIANCE METER

The Megger PVM210 Irradiance Meter is a vital tool for solar and photovoltaic engineers seeking a compact, efficient device to measure solar power accurately. This pocket-sized meter is particularly designed for optimal convenience and practicality, featuring a 33/4 digit LCD display that offers a range up to 1999 W/m², making it ideal for assessing the incident angle and positioning of solar panels.

One of the standout features of the PVM210 is its ability to be used single-handedly, thanks to its integrated solar detector and meter within one unit. This design is incredibly beneficial for engineers who need to operate the meter while on sloping roofs or atop ladders, where managing multiple pieces of equipment is cumbersome and unsafe.

The meter’s display is not only easy to read but also includes a measurement hold feature, allowing for fast and precise readings of solar power. This quick data acquisition is essential for initially determining the optimum placement of photovoltaic panels. Moreover, the PVM210 is equipped to assist in calculating short-circuit currents, an important aspect for verifying panel specifications provided by manufacturers. This is done in conjunction with a suitable ammeter, enhancing the meter’s utility in practical field applications.
