The precision barometer is a portable barometric datalogger designed for measuring atmospheric pressure, temperature and relative humidity, featuring an integrated barometric sensor and colour graphic LCD display. It is intended for environmental monitoring, meteorological inspections, laboratory activities, field verification and applications where atmospheric pressure trends must be recorded with high accuracy.
The internal barometric sensor is a high-accuracy piezoresistive type operating in the range 0…1350 hPa, with 0.01 hPa resolution. The instrument can also display pressure in different units including Pa, hPa, kPa, mbar, bar, atm, mmHg, mmH2O, kgf/cm², PSI, inHg and inH2O.
In addition to barometric measurement, the instrument provides more complete environmental analysis through connection of external probes. The 8-pole connector input allows the use of 4-wire Pt100 probes, combined temperature and relative humidity probes, and absolute, relative or differential pressure probes through the PP471 module. SICRAM probes are automatically recognized by the instrument and internally store calibration data, serial number and identification information.
When a combined temperature and humidity probe is connected, the barometer can calculate psychrometric quantities useful for environmental analysis, including dew point, wet bulb temperature, absolute humidity, enthalpy, mixing ratio, saturated and partial vapour pressure, as well as DI and NET comfort indices.
The datalogger function allows manual or automatic recording with configurable interval. Data are stored directly on SD card up to 8 GB in CSV format, simplifying archiving and post-processing activities. The display can show up to 24 quantities simultaneously, with visualization of three numeric values and real-time graphs for monitoring measurement trends.
The instrument includes a mini-USB port for connection to PC or external power supply, and an RS232C output with RJ12 connector for connection to a serial printer. Through DeltaLog9 software it is possible to start and stop recording, download SD card data, configure parameters, display measurements in tables or graphs, acquire data in real time and monitor battery status.
Power supply can be provided through internal rechargeable lithium-ion battery, external power supply or PC USB port. Battery autonomy reaches up to 15 hours of continuous operation, while automatic power-off can be configured at different intervals. The protective rubber holster with magnets, lightweight construction and IP64 protection rating make the instrument suitable for field and operational activities.
The HD3114B/C version is also available, supplied with ACCREDIA certificate for pressure calibration, recommended when barometric measurements require accredited metrological documentation.

FAQ – Precision barometer
What is a precision barometer used for?
It is used to measure and record atmospheric pressure with high accuracy. It can also acquire temperature, relative humidity and additional pressure measurements through compatible external probes.
What is the measurement range of the barometric sensor?
The integrated sensor measures from 0 to 1350 hPa, with 0.01 hPa resolution.
Does the instrument only measure barometric pressure?
In addition to atmospheric pressure, it can acquire temperature with Pt100 probes, temperature and relative humidity with combined probes, and absolute, relative or differential pressure through the PP471 module and compatible probes.
What does it calculate with a temperature and humidity probe?
With a combined probe it can calculate dew point, wet bulb temperature, absolute humidity, enthalpy, mixing ratio, saturated and partial vapour pressure, DI index and NET index.
Can the data be recorded?
Yes, the instrument records data on SD card up to 8 GB. Logging can be manual or automatic, with configurable interval according to the monitoring duration and application.
Can it be connected to a PC?
Yes, PC connection is performed through mini-USB port. Using DeltaLog9 software it is possible to configure the instrument, download data, display tables and graphs, acquire measurements in real time and export results.
Can it be connected to a printer?
