Barometer MSB181 developed and manufactured by MicroStep-MIS, is designed for use in meteorological and agrometeorological applications that require accurate measurement.


  • Digital output
  • Fully temperature compensated
  • Accuracy ±0.3 hPa
  • Long-term stability ±0.2 hPa/year
MSB181 barometer weighs only 135 g and consumes as little as 6 mA power (nominal) while in operation. The advanced sleep mode functionality reduces the power consumption even more and provides fast startup for applications where instant pressure readings are required.

MSB181 is operable in temperature range from -40 °C to +60 °C. Users may choose either SDI-12 or RS-485 data output version. The excitation range is from 6 to 16 V DC. A 4 millimeters barbed fitting is used for pressure connection. MSB 181 comes factory calibrated with a manufacturer calibration certificate.
