The BT250 Energy Tester is a rugged, easy-to-use instrument designed to assess the performance of REO single-circuit blasting machines (specifically models CD450B-50J and CD600B-100J). It provides nominal test values of energy output as a percentage of rated energy, accurate to within ±5%, giving operators confidence that their blasting machine is delivering the intended output before each use.
Built for field conditions, the tester features a self-test function that checks both instrument accuracy and battery condition, indicated through visible LED bars when the tester is operating correctly. The easy-to-read bar graph display shows the percent of rated energy after a machine is fired into the tester, helping technicians quickly assess performance without specialized equipment.
The BT250 boasts a rugged, weather-resistant nylon case with heavy-duty terminals for fast, reliable connections to blasting circuits, making it suitable for almost any outdoor blasting environment. It features automatic turn-on and shut-off, and uses common alkaline batteries that offer long life with up to 800 machine tests per set. Key Features:
Measures blasting machine energy output as a percentage of rated energy (±5% accuracy).
Self-test mode confirms tester function and battery status.
Rugged, water and corrosion-resistant case for dependable field use.
Heavy-duty terminals and simple connection leads.
Automatic on/off operation with easy battery access.
Long battery life (up to ~800 tests).
Ideal for blasting crews and safety personnel who need a quick, reliable way to verify blasting machine output before and after use, the BT250 Energy Tester is essential equipment for modern blasting operations.
