The XiTRON 6010 Portable Phase Angle Voltmeter offers economical phase and amplitude measurements in the 10Hz to 10kHz frequency range with 0.5º accuracy in a battery-operated instrument. (read more)

The 149-10A is a digital voltmeter that can measure high voltages up to a ｱ10kV AC and DC at high accuracy. Its high input impedance (1000M ohm) make it suitable for measurement of high impedance voltage circuits. Since it has a high accuracy despite its small size and light weight, it can also be easily used as a portable calibrator (read more)

The newest member of the XiTRON PAV family, the 6250 comes pre-configured for most LVDT/RVDT or sunchro/resolver tests, and is ready to go – right out of the box. The instrument requires less set-up and maintenance than competing products. And, because of its simplicity of operation, the 6250 can be used by virtually anyone who wants access to results more quickly and more reliably. (read more)

Davis Inotek Instruments offers five models of voltlmeters/phasers. The HD994003 are single stick voltmeters having one resistive probe, digital metering and ground lead. The others are two stick phasing voltmeters with connecting cord and digital metering. (read more)

The Laureate Model DC Digital Voltmeter & Ammeter is a UL-listed, 5-digit panel meter with 0.01% full-scale accuracy and read rates up to 60/sec. Such high read rates are ideal for peak capture, alarm and control, and real-time computer interface. The Laureate DC is ideal for use with external current shunts, which typically produce 50 mV or 100 mV at their rated maximum current. (read more)

Our extensive experience with miniature pressure gauges makes us eminently qualified to meet your requirements. In fact, its not unusual for us to have already built a gauge that's functionally identical to the one you need. But when you're up against a real challenge, look to QED for an innovative solution.

Vacuum Research's thermocouple vacuum gauge is a simple and low cost instrument for vacuum measurement in the popular 1 to 2000 mTorr range (microns). A 0 to 5 VDC analog output is standard on both the indicator and dual set point controller models. Operates with the gauge tubes listed below or any Varian 531 or 536 tube. (read more)

The convection gauge is the lowest cost instrument that can provide a continuous monitoring and control of your vacuum system from atmosphere all the way down to 1 mTorr. (read more)

Differential Pressure Plus, Inc., has established itself as the leading manufacturer of high-quality, low-cost differential pressure indicators for the filtration industry. (read more)

QED manufactures precision helically wound Bourdon tube pressure gauges, pressure switches and pressure gauge/switch combinations for a wide range of demanding applications.

The Bourdon tube design offers both extreme simplicity and reliability. When pressure is present at the tubes open end, it causes the tube to unwind predictability. (read more)
