Ametek Calibration Instruments has further enhanced its range of pressure generation products with the launch of the T-960, T-970 and T-975 pneumatic calibration pumps. The T-900 series calibration pump is used to generate pressure and vacuum (specific models) for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure tests may be carried out in laboratories, workshop or on site at the measuring point.
