The CARBAS is a pressure gauge with two measuring ranges and auto-range function, which was developed especially for mobile use.
It has a built-in lithium-ion battery, which can run for up to 20 hours, as well as intelligent charging electronics with automatic charging shutdown. The CARBAS uses state-of-the-art microprocessor technology to linearize the waveform, as well as the most accurate, temperature-compensated sensors, achieving extremely high accuracy and excellent dynamics. For the basic unit “mbar”, the CARBAS has two different measuring ranges, which can be switched manually, as well as an auto-range function, which automatically selects the appropriate measuring range.
It has a generously dimensioned, clearly readable graphic display on which the measured value, as well as unit, damping, battery status and measuring range are shown clearly.
The USB interface allows a bi-directional communication for the configuration of the devices, as well as the digital, serial output of the measured value with free software under various operating systems. As a result, all relevant functions can be controlled via the software as well as via the well-designed control panel.
The devices of the CARBAS series offer the possibility to switch the unit of the measured value via a button or via software. For this purpose, four additional units are available in addition to the basic unit “mbar”.
They are also equipped with an adjustable 9-stage damping for calming the measuring signal at fluctuating or pulsating pressures. The devices are calibrated with air by default, but are also suitable for the measurement of other dry, non-corrosive gases. Due to their splash-proof housing (protection class IP65), the devices of the CARBAS series are extremely robust and insensitive and thus enable very precise measuring results even in rough environments.
The high dynamic range, the robust IP65 housing as well as the integrated lithium-ion battery, the CARBAS embodies the flexibility, equipment diversity and precision that can only be found with mensaura devices.
