DT-1337 is mainly used to measure the maximum power generation of photovoltaic panels.
Under the same solar intensity, the higher the maximum power generation, the better the quality of photovoltaic pan- els. The color LCD display can read the data more clearly and intuitively under the light and reflect the curve characteristics of the data.

 

Features

The maximum generating power can reach 800W

Adjustable manual measurement mode and automatic measurement mode

Multiple protection circuit

High-precision measuring chip

With graphical data analysis
