Digital Barometer MSB780 developed and manufactured by MicroStep-MIS, is designed for use in professional meteorological and aviation applications that require reliable and highly accurate measurement, fast dynamic response, and advanced long-term stability.
Digital Barometer MSB780 is built to withstand even the most challenging environmental conditions, which are often faced in various environmental monitoring applications. Barometer MSB780 is a low power consumption microprocessor controlled sensor suitable also for solar and battery powered applications. Barometer is operable in temperature range from -50 °C to +80 °C. The excitation range is from 5 to 35 V DC. MSB780 is a robust product made of durable hardware components enclosed in heavy-duty metal IP66 enclosure. This barometer comes factory calibrated with a manufacturer calibration certificate.
