The HD3114B is a handheld pressure, temperature and humidity data logger with a large (43 x 58 mm) color graphic LCD display.
The device has a built-in precision air pressure sensor for measuring atmospheric pressure and calculating the following barometric and altimetrically derived parameters:
- barometric tendency (numerical) and trend (decrease, steady, increase),
- Height,
- QNH (atmospheric pressure) at mean sea level).
The device can display the temperature of the air pressure sensor.
The input for SICRAM probes (intelligent and interchangeable probes that can store calibration data in memory) allows the connection of:
- 4-wire Pt100 temperature sensor.
- Combined probes for temperature and relative humidity.
- TP704 / TP705 absolute / relative / differential probes with PP471 module.
The device automatically detects the type of connected SICRAM probe. The probes are factory calibrated and interchangeable. Calibration reports or certificates are available upon request.
By connecting a combined temperature and relative humidity probe, the device calculates the following values derived from the humidity:
- dew point temperature,
- wet bulb temperature,
- absolute humidity,
- Mixing ratio,
- Partial vapor pressure,
- Saturation vapor pressure and
- Enthalpy.
In addition, the DIS discomfort index and the NET index (Net Effective Temperature) are calculated.
Simultaneous display of three variables in numerical form. Real-time visualization of a measured value graph on the display.
Units of measurement can be selected according to the measured physical quantity.
Data logging function with data saved in CSV format directly to the SD memory card, allowing for long-term logging (for example, with a 4 GB SD card, the logging duration is in order of months, even when recording large quantities with a minimum logging interval of 1 second). Logging intervals are user-configurable. Logging can be started and stopped automatically or manually. The date and time of each recorded sample is saved. Measurement reports are automatically generated in PDF format on the memory card.
