Product Highlights
The LC20 is a robust device that measures and displays pressure readings on a large, backlighted screen. The LC20 has the ability to show High and Low pressure values on-screen, change between 15 different engineering units or add custom engineering units. The included PC FieldLab Desktop software can be used for calibration, testing and live viewing of pressure.
The Field Gauge LC20 has all the toughness and portability of our LC10 model, but with an impressive ± 0.1% of full scale accuracy. It's the reference-grade gauge you can take with you anywhere. Perform logging and live viewing of pressure over USB, or choose the wireless option and monitor tests from the comfort of your truck.
Built for the Field
- Large, easy-to-read display with intuitive controls and bright backlight
- Tough powder coated aluminum exterior that withstands abuse and cracking and keeps the internal components functioning with extreme precision, even in extreme conditions
- Waterproof up to 1 meter (IP67)
- Made in the USA
Fast, Accurate and Easy to Use
- ± 0.1% full scale accuracy (ASME B40.100 Grade 4A/ISO Class 0.1)
- Quick, reliable Zero function using a single button
- Convenient High / Low readings maintained with quick reset for monitoring peaks and valleys
It's All About Options
- 15 engineering units to choose from
- Option to add custom engineering units using the included FieldLab software
- Available in 11 pressure ranges from 5 psi / 35 kPa to 10,000 psi / 70 Mpa, a compound vacuum/pressure gauge from -/+15 psi, and a digital vacuum gauge measuring up to 30 inHg / 760 mbar
- Connect to a PC via USB or wireless to change settings or to perform data logging.
The Right Tool for the Task
- General pressure monitoring
- Calibration of analog pressure gauges and transmitters
- Pressure switch testing (need a multimeter to measure switch closure)
