A measurement/calibration/probe storage apparatus particularly suitable for measuring pH of fluids and slurries used in the treatment of oil and gas wells. The apparatus includes an enclosure having a conduit for the conveyance of a fluid or slurry therein, a flow chamber being in fluid communication with the conduit, a probe sensor for measuring a preselected attribute of a fluid, or slurry, residing within, or, passing through the flow chamber. The apparatus further includes an electronic processor in electrical communication with the probe sensor for calculating and providing a display of the attribute being measured and a calibration chamber being configured to receive the probe sensor. At least one calibration fluid container being in fluid communication with the calibration chamber is also provided. A control valve is provided for controlling the flow of fluid from each calibration fluid container into the calibration chamber and for controlling the draining of the calibration chamber.
