Metal- and X-Ray-Detectable Calculators

Made with metal and chemical additives, these calculators trigger metal detectors and X-rays if they fall into your food line, helping you comply with Hazard Analysis and Critical Control Point (HACCP) programs for food safety. Their bright blue case makes them easy to spot and retrieve. Because their case is sealed, they have few gaps where germs could grow, reducing the chance of illness. They’re also safe to touch food, since they’re FDA compliant.
These calculators are solar powered, but they come with backup batteries for dim areas. The lanyard breaks away at the clasp if it’s caught, so you can quickly remove it in an emergency.

Scheduling Wheel Charts


Plan upcoming projects by finding completion dates and setting milestones. Line up the arrow with the start date, then use the inner wheel to count days or weeks to figure out when you'll complete the task. Or, line up the number of weeks the task will take with your deadline, and then use the outer ring to determine when you should start and your check-in dates. On the back, you can look up the day of the week for any date through 2035.

Power Consumption Meters


Measure the amount of power your devices draw and calculate energy costs with these consumption meters. Plug them directly into an outlet, and plug your tool or appliance into the front of the meter. To track your power costs, enter the local price per kilowatt-hour (kWh) into the meter, and they’ll display the total amount you’re spending. They also help you monitor the quality of electricity coming from your outlet.
These meters meet U.S. and international safety standards. Rated CAT II, 150V, they can be safely used with most single-phase AC appliances and tools.
