The CI Estimator 4019 delivers 12-digit internal precision with pre-programmed material keys that save contractors 20+ keystrokes per calculation on common estimating tasks. At 4.15 oz including protective case, this jobsite calculator handles everything from drywall sheets to concrete yards without needing a smartphone or laptop.
Montana contractors face unique challenges — from bright summer sun to winter indoor work, and job sites can be hours from the nearest town. The 4019’s dual-power design with integrated solar panel and CR2016 battery means it works reliably whether you’re framing in July sunshine or estimating a basement remodel in February.
Purpose-Built Material Keys Transform Estimating Speed
The real power comes from pre-programmed calculation keys for common materials (studs, sheets, board feet, floor tiles, blocks, bricks, gravel, paint). Instead of punching in formulas, contractors hit dedicated buttons that instantly calculate quantities based on dimensions entered.
Store custom constants (e.g., grout width, tile size, post spacing, paint coverage) turns repetitive calculations into single-button operations. Set your standard 16-inch stud spacing once. The calculator remembers it for every wall estimate until you change it.

The paperless tape function to review previous 20 entries catches mistakes before they become material orders. Check your math without starting over.
Jobsite Durability Without the Bulk
360-degree ‘Armadillo-style’ protective hard case shields the calculator from drops, dust, and Montana’s temperature swings. The case design earned its name — it wraps completely around the unit like armor plating.
The Material Estimator is designed for contractors, trades people, and estimators who need to estimate materials and costs for concrete, fences, decks, bricks, tile, flooring, gravel, painting, drywall, panelling, and more. It helps users quickly and easily calculate material costs and allowances, and get exactly the materials they need. Reducing estimating errors will same time and money. Solar/battery power.
Physical specs that matter on job sites:
- Weight: 4.15 oz (118 g) including protective case
- Dimensions: 5.7 x 3.0 x 0.65 inches
- Power: Integrated solar panel and one 3V CR2016 long-life battery
No complex setup required. The device is dual-powered and works out-of-the-box. Users should consult the included pocket guide to learn function keys and how to store material constants.

The calculator includes English/Spanish Pocket Reference Guide and CR2016 3V battery. One-year limited manufacturer’s warranty. Compliance standards not explicitly listed, but generally meets CE/RoHS for small electronics.
Common use cases involve quick material estimates, rough cost calculations, and on-the-fly measurements during construction or remodeling projects. Overall, the calculator is appreciated for its reliability and simplicity.
For Montana contractors working everything from Kalispell custom homes to Great Falls agricultural buildings, the 4019 eliminates smartphone fumbling and laptop hauling. The dedicated material keys and fractional precision handle real construction math — not theoretical exercises.
Frequently Asked Questions
Q: How does this compare to the Construction Master Pro calculators?
The 4019 focuses on material quantities and costs vs. the Construction Master Pro’s focus on geometry/layout (rafters, stairs). If you’re estimating how many sheets of drywall to order, the 4019 excels. For calculating stair rise and run, you’d want a Construction Master.
Q: Will the solar panel work in Montana winters?
The dual-power design means the CR2016 battery takes over when solar isn’t sufficient. Indoor winter work relies on the battery, which lasts months with the auto shut-off after 8-12 minutes of inactivity.
Q: What materials can this calculator estimate?
Pre-programmed calculation keys for studs, sheets, board feet, floor tiles, blocks, bricks, gravel, paint cover most common construction materials. The instant area and volume calculations with cubic/square format support handle materials sold by area or volume.
Q: How accurate are the fractional measurements?
Fractional results displayed to nearest 1/16th inch with 12-digit internal precision. That’s more than accurate enough for material ordering where you’ll round up anyway.
Q: What’s included with the calculator?
The package includes the CI Estimator Calculator 4019, 360-degree protective hard cover, English/Spanish Pocket Reference Guide, and CR2016 3V battery.
