These DV-4D tubes have a standard 1/8 inch male NPT vacuum fitting are brand new with full Teledyne Hastings warranty (DV-4D Stock Number 55-19).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 Teledyne Hastings Instruments DV-4D thermocouple gauges have a reputation built upon exceptional stability, accuracy, and reliability under the most demanding conditions.

Teledyne Hastings DB-16D Reference Tube, Equivalent Gauge Tube DV-4 series, Range 0-20 Torr. PN: DB-16D, NIST-DV-4D The Teledyne Hastings Instruments (THI) DB-16D Reference Tube is an evacuated, sealed vacuum gauge tube accurately calibrated to precisely simulate a gauge tube at a given operating pressure. This Teledyne Hastings Instruments DB-16D Reference Tube it is electrically equivalent to the Gauge Tube DV-4 series Range 0-20 Torr, used with THI instruments. The DB-16D Reference Tube permits quick and easy recalibration of THI Vacuum Gauge Indicators by merely plugging the instrument into the reference and adjusting the calibration “current set” potentiometer until the instrument reads the exact pressure noted on the reference. THI Reference Tubes are available equivalent to most THI Gauge Tubes. Part Number DB-16D (Old Part Number NIST-DV-4D). The applications for The Teledyne Hastings Instruments (THI) DB-16D Reference Tube: THI Vacuum Gauge Indicators or Controllers can be checked or recalibrated in seconds by merely plugging the gauge tube cable into the reference tube. If calibration adjustment is necessary, the “Current Set” potentiometer is adjusted until the instrument indicates the pressure marked on the reference tube. The customer now knows his instrument is correctly calibrated. Whenever cable lengths between gauge tube and instrument are changed, some error may be introduced, requiring that the instrument be readjusted to compensate for any losses involved. By plugging the Reference Tube into the new cable and readjusting the instrument for a correct reading, this “error” is eliminated. Choose the reference tube that is equivalent to the glass or metal THI Gauge Tube you are now using. The Reference Tube will be matched and sealed at a pressure falling on the lower portion of the scale and calibrated accurately at this exact pressure. For example, if an instrument uses a DV-6M Gauge Tube, a DB-20 Reference Tube is ordered. If a customer receives a reference tube marked “at 10 mTorr”, this is the pressure to which the indicator should be adjusted when plugged into the reference tube. THI Reference Tubes employ the same THI noble metal thermopile used in all THI Thermopile Vacuum Gauge Tubes. The thermopile is sealed in a glass capsule that has been evacuated, baked, outgassed, sealed, and then aged to ensure stability over long periods of time. The sealed capsule is then housed in a protective metal shell to provide a rugged, trouble-free assembly. Considerable care and time are required in the manufacture to obtain the high degree of precision and stability required for the reference tube. The THI Reference Tube maintains its calibration over long periods of time. However, for applications requiring the highest possible degree of accuracy, a periodic return of the reference tube to the factory for a check and recalibration may be desirable. An annual or semiannual check assures the customer of an accurate and reliable reference at all times.
