The LPX low-pressure calibrator is a high-precision calibration instrument for pressures between -0,85 bar and 10 bar (after taring to ambient pressure). The functional calibrator is supplied in a sturdy carrying case and pressure can be quickly generated manually. It is therefore ideal for use in the field. The pressure is measured by the integrated LEX1 manometer and output both on the display and via the RS485 interface. Additional functions such as zero point resetting, peak and trough pressure value indication and leak measurement make it even easier to take measurements. Pressure Ranges:-0,85…10 bar Accuracy:0,05 %FS Interfaces:RS485 Display:5-digit LCD display Special characteristics:For air pressure

The DCX-22AA-CTD data loggers measure conductivity and temperature as well as pressure, along with the depth of bodies of water. They compensate for the air pressure using an additional, water-tight absolute pressure sensor with a stainless steel separating diaphragm. Unlike gauge pressure systems with a capillary tube, this system is completely resistant to moisture and can therefore be immersed. Thanks to their long-life battery, they can keep recording measurement results for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.
