Description

PRO 24x – Absolute handheld pressure gauge – vacuum gauge, integr. sensor, graphic display

INTRODUCTION
PRO 241 and PRO 245 are absolute pressure high class professional handheld meters/vacuummeters with a rich set of features, high grade robustness and operating comfort for safe and reliable use. PRO 245 also has data logging capability.
FEATURES
Display
The multilingual large dot matrix/clear text LCD has ergonomic wide-angle visibility from daylight to darkness, thanks to the backlight. It displays either large scale values, statistical data or the chart of a variable measurement history. The HOLD feature allows freezing the measurements on display, while the REL feature allows showing the measurement against the measured value. Many units of measurement available: hPa, kPa, bar, mbar, inHg, mmHg
Data Logging (only PRO 245)
Large storage capacity: up to 1 million data, file system based. The logged data are store in CSV files that can be easily viewed connecting the instrument to a PC via USB: the instrument is seen by the PC as a mass storage device, the data can be read oud and evaluated without software necessarily needed. Automatic log with configurable interval.
The instruments integrate a Real Time Clock: date and time of each logged sample are stored.
Application Software
addition to CSV files, the free user-friendly basic ProXware PC application
software allows for examination of a large amount of logged data.
Alarm
Configurable alarm thresholds and optionally hysteresis can be set. LCD indication
and buzzer activation when thresholds are exceeded.
Ergonomics
The construction allows for both one-handed use as well as bench-top use with the foldable back stand. Side rubber protection offers a secure grip during the use in the field.

APPLICATIONS

APPLICATIONS

  • Vacuum Systems Monitoring

    • Accurate measurement of vacuum levels in industrial or laboratory systems.

  • Absolute Pressure Testing

    • Measurement of atmospheric or sealed system pressure in R&D and industrial environments.

  • HVAC Systems

    • Monitoring vacuum/absolute pressure in air conditioning or heating systems.

  • Calibration and Validation

    • Used as a reference device for calibrating pressure-sensitive instruments.

  • Environmental Monitoring

    • Measuring atmospheric pressure for weather stations or altitude-sensitive processes.

  • Cleanroom and Pharmaceutical Pressure Control

    • Maintain strict absolute pressure conditions in sterile environments.

  • Data Logging for QA/QC (PRO 245 only)

    • Long-term pressure tracking for audits, process control, or research reports.

  • Leak Detection in Sealed Systems

    • Identify pressure drops over time to detect leaks in containers or piping.

  • Portable Field Inspections

    • Ideal for mobile technicians inspecting pressure conditions on-site.
