Crystal nVision Handheld Reference Recorder

IECEX Ex ia IIB T4 Ga or T3
(SIR 09.0053X)

Accurate enough to replace a deadweight tester
Rugged enough to operate in 1m of water
Portable enough to log data anywhere
... there's never been anything like this!

• Gauge / absolute pressure data logger up to 1000 Bar
• Differential pressure at 0.025% of reading accuracy
• Temperature, voltage, mA and switch measurement
• 1 million point data logging memory
• 10 readings per sec from 2 modules simultaneously

The Crystal nVision records and displays graphical trending of pressure, electrical and temperature signals live on screen. With a range of interchangeable modules that are easy to remove and replace in the field, one portable, handheld nVision is flexible and accurate enough to function simultaneously as a deadweight tester replacement, a high accuracy pressure gauge / multimeter / thermometer, and a high frequency digital chart recorder.

The nVision is IECEx and ATEX certified as intrinsically safe for use in potentially hazardous gas and dust areas, and will comfortably handle operating temperatures from -20 to +50°C. An IP67 rated, submersible, dust-proof and impact resistant housing ensures the nVision is rugged enough to cope with the harshest of environments.
