Description
Overview
The United Instruments LPC-30 is a precision pressure calibrator designed for calibration and testing of pressure instruments in laboratory and field environments. It provides accurate pressure measurement and control with a measurement range of -1.5 to 11.5 inches of water column (-3.75 to +27.5 mbar), making it ideal for low-pressure applications. The instrument features both AC line power and battery operation for portable field use, with a 2.2 AHr NiCad battery providing approximately 2 hours of operation at 50% duty cycle.
Key Features
- Measurement range: -1.5 to 11.5" H2O (-3.75 to +27.5 mbar)
- Measurement accuracy: ±0.035% of full scale at 25°C (includes zero, span, hysteresis, and repeatability errors)
- System accuracy: Lab environment ±0.035% of full scale; Field operation (10-30°C) ±0.05% of full scale
- Repeatability and hysteresis: ±0.015% typical
- Between-point linearity: ±0.01% typical
- Control range: -10" to +10" H2O (-25 to +25 mbar) standard
- Maximum overpressure: 5 PSI (347 mbar)
- Solid-state piezoresistive strain gauge sensor with servo-actuated balanced differential piston array
- Alphanumeric fluorescent display (2 x 20 characters)
- Multiple pressure units: in H2O, mm H2O, cm H2O, in Hg, Torr, cm Hg, mbar, Pascal, kPa, PSI
