Calculated Industries 4090 Sheet Metal/Hvac Pro Calc Calculator, Hvac Pros With

The Sheet Metal/HVAC Pro Calc was designed for and with one of the nation’s largest industrial training organizations to be a simple-to-use and versatile tool for skilled tradesmen. Its advanced functions are easy to learn and can solve the most challenging calculations. Boost accuracy, cut costly errors and upgrade training along with job performance for greater productivity. BUILT-IN FUNCTIONS include Fan Law Functions to simplify Test and Balance (TAB) with CFM, RPM, SP, BHP, velocity and velocity pressure. Sheet metal functions include x, y, r (radius), theta, and Seg Radius; and converts between polar and rectangular coordinates. Trigonometric functions include Sine, Cosine, Tangent, Arcsine, Arcosine, and Arctangent. Plus, ArcK Constant is built-in for fast Arc Length solutions. Laws of Cosines calculate non-90° triangles. The offset functions let you calculate “S”- shaped bends in ductwork, solve for wrapper length, centerline radius, and angle. ORDER OF OPERATION calculator lets you enter complex formulas. It has the parenthesis operators for formula entry. You can also perform square, cube, square root, and cube root calculations. Plus, it works as a regular calculator. It has a backspace key for last entry editing. CONSTRUCTION MATH FUNCTIONS built-in. Work in and convert between building dimensional formats including feet, inch, fractions, and metric. Calculate areas and volumes. Perform square-ups, slopes, and more. Determine regular and irregular hip/valley rafter lengths along with plumb, level, and cheek cut angles. Calculate complete stair layouts and circle, column/cone surface area, and volume solutions. Complete D:M:S to decimal degree conversions. Includes a rugged, shock, dust, and moisture resistant Armadillo Gear case, easy-to-follow User’s Guide, a Quick Reference Guide, 2 Long-life batteries (LR-44).
