Calibrate / Measure / Record: nVision

New Intrinsically Safe Reference Pressure Recorder!

Reference Pressure & Temperature Recorder!

It's not just a new pressure calibrator or a new pressure recorder. It’s a field calibrator that can display recorded data graphically on a high resolution screen. No need to stop a test to analyze data on a PC. Stored data, or data being recorded can be displayed graphically, with the ability to zoom into specific events, or zoom out to get a big picture of your test. There's never been anything like this!

Pressure accuracy to 0.025% of reading
Field-replaceable modules: pressure, temperature, current and voltage
Temperature compensation from -20°C to 50°C
ATEX/IECEx intrinsically safe
Log and display 500,000 points at up to 10 readings/sec on up to two modules simultaneously
IP67 (1 meter submersion for 30 minutes)
Uses our new CPF hose and fitting system (leak-free and finger tight to 10K PSI)
Interactive real-time graphing of measurements

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!
