A&D Weighing
The EK-EP Series of intrinsically safe compact balances (photo) are approved for both U.S. and Canada for Zone 0 or Division 1 atmospheres where vapors are constantly present and could be accidently ignited. The Series’ models have capacities of 300 and 3,000 g, as well as 12 kg. The portable design means that weighing can take place near the vapor source or inside fume hoods and explosion-proof enclosures. Because the balances are powered by batteries rather than electrical mains, they do not require installation by a qualified electrician. — A&D Weighing, San Jose, Calif.
