CLIVE (AP) — A California-based private equity firm has bought an Iowa company that produces breath-alcohol monitoring devices.

The Des Moines Register reports that Consumer Safety Technology says the purchase by ClearLight Partners, of Newport Beach, Calif., will provide the capital the Clive company needs to expand. It has about 145 employees nationwide.

Consumer Safety Technology CEO Dave Arringdale says ClearLight understands “what it takes to make these things work, and they are willing to invest in and support us.”
