Extending its line of hand-held measurements, this company has added the model CPH6510 intrinsically safe pressure calibrator (photo). With an accuracy of 0.025% of span and various additional functions, the new device is suitable for a wide range of applications, including those in hazardous areas. It is available with either one or two built-in reference pressure sensors. This allows 24 different measuring ranges of up to 700 bars to be covered. The instrument also accepts transmitter output signals (0–24 mA) and the ambient and medium temperature (–40 to 150°C) is measured by a resistance thermometer. A pressure-switch test function completes the functionality. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
