產(chǎn)品介紹：
edyne Hastings DV-6R Ruggedized Thermocouple Vacuum Gauge Tube for 0.001 to 1 Torr Range （Stock Number 55-38R）
edyne Hastings DV-6R ruggedized thermocouple vacuum gauge tubes have a rugged steel housing and can measure pressure between 0.001 and 1 Torr （1 to 1000 mTorr）. edyne Hastings DV-6R vacuum sensors are calibrated for nitrogen or air, but conversion factors for other gases are available. The edyne Hasting DV-6R tubes are matched and interchangeable without calibration adjustments. The DV-6R thermocouple tubes are for use with edyne Hastings Digital or Analog VT-6 thermocouple gauge controllers. These DV-6R tubes have a standard 1/8 inch male NPT vacuum fitting are brand new with full edyne Hastings warranty （DV-6R Stock Number 55-38R）.
Thermocouple sensors （thermal conductivity gauges） rely on the fact that the ability of a gas to conduct heat decreases with pressure. In this type of gauge, a wire filament is heated by running current through it. A thermocouple or Resistance Temperature Detector （RTD） can then be used to measure the temperature of the filament. This temperature is dependent on the rate at which the filament loses heat to the surrounding gas, and therefore on the thermal conductivity. A common variant is the Pirani gauge which uses a single platinum filament as both the heated element and RTD. These gauges are accurate from 10 Torr to 10−3 Torr, but they are sensitive to the chemical composition of the gases being measured （from Wikipedia.org）.
The edyne Hastings Instruments DV-6R thermocouple gauges have a reputation built upon exceptional stability, accuracy, and reliability under the most demanding conditions. edyne Hastings DV-6R thermocouple pressure measurement gauges are used in glove boxes, cryogenics, vacuum furnaces, pharmaceutical production, freeze drying, agricultural processes, air conditioning, thermal food containers, plasma coating, refrigeration （HVAC）, accelerators, appliance manufacturing and others
