Sensor

Precision piezo-resistive

Measuring range

0…1350 hPa

Resolution

0.01 hPa

Accuracy @ 23 °C

± 0.1 hPa (500…1200 hPa) / ± 0.2 hPa (remaining range)

Accuracy @ full temperature range

± 0.3 hPa (500…1200 hPa) / ± 0.4 hPa (remaining range)

Long-term stability

0.25 hPa / year

Available units of measurement

Pa, hPa, kPa, mbar, bar, atm, mmHg, mmH₂O, kgf/cm², PSI, inHg, inH₂O

Power supply

Rechargeable internal 3.7 V Lithium battery, capacity 2250 mA/h, JST

3-pole connector.

Optional external 5 Vdc/1A power supply (SWD05) to be connected at the mini-USB connector of the instrument.

Powered by the PC USB port (at least 500 mA) when connected to the PC.

Battery autonomy

15 hours of continuous operation (typical duration starting from a fully charged battery and with one Pt100 probe connected). The actual battery

life depends on the type of the probe connected.

Logging interval

1, 5, 10, 15, 30 seconds / 1, 2, 5, 10, 15, 20, 30 minutes / 1 hour

Storage capacity

SD memory card with capacity up to 4 GB.

The logging duration depends on the number of logged quantities and on the capacity of the SD card employed. For example: with a 4GB SD card the duration of the logging is in the order of months, even when many quantities are recorded with the minimum logging interval equal to 1 s.

Inputs

1 input with 8-pole DIN45326 connector for Pt100 temperature probes, combined temperature and relative humidity probes, TP704/TP705 pressure probes with PP471 module.

The barometric sensor is integrated into the instrument.

Clock stability

1 min/month maximum drift

Display

Color graphic LCD. Visible area 43 x 58 mm.

USB Connection

1 USB port with mini-USB connector.

RS232C Connection

1 serial RS232C output with RJ12 (6P6C) connector for connecting to a serial printer. Baud Rate selectable from 1200 to 115200.

Auto power off

Configurable after 2, 5, 10, 15, 20 or 30 minutes from last pressure of a key, with battery supply. It can be disabled.

Automatically disabled when powered from external supply.
