Increase sales by improving the quality of your sales presentation. Bring your windows performance to life in front of your customer, by incorporating the CRL Solar/BTU Power Meter into your sales pitch. The SP2065 meter is extremely simple to use and allows you to demonstrate the solar transmission percentage of your window product. Talk to your customer in a simple language they can understand: Solar Transmission Percentages. By doing so, you will quickly win your customer’s confidence in your product. For those customers who prefer to deal with BTU measurements, the SP2065 meter can be switched into BTU mode as well, to measure incident solar energy. Simply press the red toggle button and you now have two meters in one. This meter can even be used to measure approximate Solar Heat Gain Coefficient (SHGC) values for windows. Even more importantly, the SP2065 can be used to identify types of Low E coatings in the field. By knowing the performance of specific coatings, the user can identify the type of coating, and perhaps even the manufacturer of the coating. Uses one standard 9 VDC battery (included).
