| 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. Backlit Display Description: 255 x 160 pixel graphical display with integrated backlight. Display rate: selectable up to 10 readings per second. Power 100?240VAC, 50?60 Hz, with international plug adapters Temperature Operating & Compensated: 10°C to 50°C (50°F to 122°F)1. Storage: 0°C to 75°C (32°F to 167°F). 1No change in accuracy over operating range for all modules. Pressure sensor must be zeroed to achieve rated specification. Humidity < 95%="" rh,=""> Enclosure Dimensions: 115mm(4.5")H x 260mm x (10.2")W x 145mm (5.7") Weight: 2.2 kg (4.75 lbs) including two pressure modules Pressure Connections Crystal CPF System: Medium Pressure Female (MPF) (1/4" medium pressure tube system with 7/16-20 threads).

* Add one digit of resolution for differential pressure measurement. Pressure Accuracy 30% to 99% of Full Scale ±(0.025% of Reading), ±(0.05% of Reading), or ±(0.1% of Reading). 0 to 30% of Full Scale ±(0.0075% of Full Scale), ±(0.015% of Full Scale), or ±(0.03% of Full Scale). Vacuum, for 300 PSI (30 bar, 3 MPa, and 30 kg/cm²) and lower pressure modules ±(0.06% of Full Scale) (typical), where F.S. = -14.5 PSIG (-1.0 bar, -99.9 kPa, -1.02 kg/cm²), not recommended for continuous use at high vacuum.

Temperature Measurement: RTD Module (P/N: RTD100) Supports Pt100 RTD or PRT (100 Ohms at 0°C Resistance Temperature Detector) sensors conforming to DIN/IEC 60751 (or IEC751) with US, Euro and Lab calibration curves. Each RTD 100 comes with P/N 3953 RTD Connection Kit. Resistance Input Range：0 - 400 Ohm range for use with 100 Ohm PRTs Resolution：0.01Ω Accuracy：±(0.015% of Reading + 0.02 Ω) Display：°C, K, °F, R, Ω TCRs：0.003850 Ω/Ω/°C (IEC 60751), 0.003911 Ω/Ω/°C (US Industrial Std), 0.003926 Ω/Ω/°C Wiring：2-, 3-, 4-wire support Current, Voltage & Switch Test: mA/V Module (P/N: MA20) Intended for use with a 4-20mA loop measurement. This module is also capable of measuring 24VDC supply voltages. Additionally the module has an auxiliary fixed output for use in switch open/closure testing. Each MA20 module comes with P/N 3952 test lead kit. mA (Current) Input Accuracy：±(0.015% of Reading + 0.002 mA) Range：0 - 55 mA Max Allowable Current：93.3 mA Resolution：0.001 mA or 0.00% Note：Inputs protected by resettable fuse Units：mA, % 4-20, % 10-50 Input Resistance：< 17.2=""> Voltage Burden：< 0.35=""> HART Resistance：250 Ω Voltage Input Accuracy：±(0.015% of Reading + 0.002 VDC) Range：0 - 28 VDC Max Allowable Voltage：30 VDC Resolution：0.001 VDC Switch Detection State：Dry Contact WARNING: Never install two (2) MA20 modules simutaneously. This configuration may permanently damage your nVision. |
