These three units beat every other comparable dry-well in the industry in performance, size, weight, convenience, ease of calibration, software, and price. In addition, the heating and cooling rate of each of these dry-wells is adjustable from the front panel, thermal switches can be checked for actuation testing, and multiple-hole inserts are available for a variety of probe sizes.
Hart dry-wells are easy to calibrate. You don't even have to open the case. This means less maintenance costs and less down time when they do need calibration.
Our Interface-it software lets you adjust set-points and ramp rates, log dry-well readings to a file, create an electronic strip chart, and perform thermal switch testing with data collection. The software is written for Windows and has a great graphical interface. Regardless of whether you want basic software or a completely automated calibration system, we've got what you want. Read about all our great packages starting on page 80.
Every dry-well we ship is tested at our factory, and every unit comes with a NIST-traceable calibration. There's no extra charge for the report, because we consider it an essential ingredient in our quality program. You shouldn't have to pay extra for calibration procedures we perform anyway.
The 3130-G2M Portable Pneumatic Pressure Calibrator is ideal for calibrating pressure transmitters, transducers, gauges and similar devices. The 3130-G2M contains everything you need to generate, control and measure pressure, as well as read the output of the device under test (DUT).
Measure and generate pressures from vacuum to 2 MPa (300 psi, 20 bar)
Internal pump can generate vacuum to -80 kPa (-12 psi, -0.8 bar) or pressure to 2 MPa (300 psi, 20 bar)
Supply pressure connection allowing the use of external gas supply up to 2 MPa (300 psi, 20 bar)
Includes variable volume for fine adjustment of pressures
Pressure measurement accuracy of 0.025% reading ±0.01% FS
Electrical measurement and 24 volt supply for close looped calibrations
Measure or generate 4 to 20 mA
Measure 0 to 30 V DC
Powered by internal, high capacity, NiMH battery or universal ac mains adapter
