This G. BRIEM Messtechnik differential pressure gauge — sometimes referred to as a differential pressure indicator or manometer — is a laboratory instrument designed to measure and display the difference in pressure between two points in a system. Instruments of this type are commonly used to monitor air handling units, filter housings, cleanroom environments, and HVAC systems, providing continuous analog feedback on pressure differentials. G. BRIEM Messtechnik is a German manufacturer specialising in precision measurement technology for industrial and building services applications.
The gauge covers a measuring range of -50 to +50 kPa, displayed on an analog scale calibrated in Pascal, with a maximum allowable pressure load of 15 PSIG (100 kPa). It is factory-calibrated for vertical mounting orientation and connects to the monitored system via two pneumatic ports located on the rear of the unit. The housing is constructed from die-cast metal with a stainless steel front plate, combining mechanical robustness with a low-maintenance, fully mechanical display. The operating temperature range spans from -6 °C (20 °F) to 60 °C (140 °F).
The display incorporates a colour-coded scale — with clearly delineated green and red zones — enabling at-a-glance status monitoring without the need for a power supply or digital readout. A manually adjustable red reference marker needle allows operators to set a visible setpoint directly on the dial face. The unit comes pre-mounted on a stainless steel installation frame, making it ready for direct integration into electrical cabinets or wall-mounted panel systems without additional bracketing.
The instrument is offered in used condition and described as fully functional, with only minor signs of wear consistent with previous service life. It is located in Germany and listed at $100.
