| Lab Reference Recorder
The nVision Lab Reference is a pressure reference recorder accurate enough to function as a laboratory deadweight tester replacement and a high-accuracy, high-frequency chart recorder. Download data as you test, view your data on the built-in LCD, and store up to 1,000,000 data points. •Gauge / Absolute Pressure Datalogger to 15 000 psi / 1000 bar / 100MPa •Differential Pressure with up to 0.025% of reading accuracy •Switch, Voltage, Current, and Temperature •500 000 data points - 10 readings per second from 2 modules Keep the nVision Lab Reference on your work bench or mount it in an equipment rack. •Uses our new CPF hose and fitting system for fast leak free connections •Displays live data graphically - no PC required •Connects to a PC to view live readings or export to tamper proof digital records •Compensates accuracy for temperature effects from 10°C to 50°C •Includes a calibration certificate with test data at 5 different temperatures from an A2LA accredited laboratory Applications •Calibrate pressure transducers, switches, transmitters, and gauges •Calibrate natural gas correctors and flow computers •Pressure relief valve testing •Field datalogging of pressure and temperature •Record water hammer events •Leak testing with simultaneous graphing of pressure and temperature •Temperature monitoring and recording •Pass/fail events for pressure bearing vessels such as gas cylinder, flow meter, etc. Included with every new nVision Reference Pressure Recorder is an A2LA accredited calibration certificate with test data recorded at 5 different temperatures - proving that it meets published specifications over the entire operating range. You won't get this kind of detailed report anywhere else! Specifications Specifications include all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.
