The SP2065 now has three units of measure built in: BTU/hr*ft^2, W/M², and Solar Transmission percentage. Switching between modes is easily accomplished by using the buttons on the new embossed style power switch that also provides a smooth front surface and a sleeker appearance. The change in power switch style is accompanied by an auto-power off circuit that will turn the meter off after a period of inactivity. This will help extend the life of the batteries in these portable devices.
