GRB Enterprise
About GRB Enterprise
GRB Enterprise was formed in 1997 to perform calibration and repair of test and measurement equimpment in compliance with ISO Guide 25 and ANSI/NCSL Z540-1.
GRB Enterprise is a partnership owned by four black American women who are committed to excellent customer service and developing a superior technical partnership with our clients.
History
Ms. Darlene Turner, President of GRB Enterprise, formed the instrument calibration, diagnostics and repair business to take advantage of her 25 years of experience working in the electronics field.
Ms. Turner has another business, Vibration Analysis Limed (VAL) created in 1990.
Vibration Analysis Limited is a consulting engineering firm that conducts vibration analysis on rotating machinery such as, moters, pumps, generators and fans. Machine vibration analysis, also referred to as Machine Condition Monitoring, is an industry accepted method of assessing a comany's critical asset health. VAL also performs calibration and repair of vibration and balancing equipment in compliance with Mil-Std 45662A, Guide 25, ANSI-2540 and in compliance with ISO 9000 and QS 9000.
VAL's Machine Condition Monitoring customer base requested VAL to calbrate more than virbation and balancing qwuipment so that they could stay in complaince with ISo 9000, and QS 9000 without having numerous calibration vendors. So in 1997, Ms. Turner and three other partners started GRB Enterprise to calibrate test and measurement equipment at GRB's lab in Columbus, Ohio or on-site at your facility.
