HATS-LR Series
For high resistance transfer standards, consider the HATS-Y Series.
The Benefits of Using Transfer Standards
In order to perform calibrations with a high degree of accuracy, reference standards must be employed at every range or decade of the measuring or calibration instrumentation. Clearly, this can be difficult and costly since these standards must be highly stable and their precise values must be known with a high degree of certainty and sufficient resolution.
To minimize the cost and difficulty, more practical means of performing such calibrations is to use transfer standards.
If one has a single standard that is calibrated by a national laboratory, one can then compare the transfer standards to the certified standard by ratio techniques. See our Technical Applications section for a full tutorial.
- Steps from 1 Ω to 100 kΩ
- Transfers from 0.1 Ω to 1 MΩ

1417 Series
The 1417 Four-Terminal Capacitance Standard consists of a 1µF standard capacitor and two precise inductive voltage dividers used to scale the value of the 1µF capacitor up to 1F in decade steps. This arrangement provides accuracy and stability unattainable with very high-value true capacitors.
- 1uF to 1F in decade steps
- 0.25% direct-reading capacitance accuracy
- 0.1% or better ratio accuracy
- Dissipation-factor standard
Data sheet and specs (.PDF Format)
Applications:
- Laboratory Standard
- Standard for Dissipation Factor
- Verification & Calibration of LCR Meters
- Working Standard
- Verification of Calibration of LCR Meters
- Capacitance Measurement Functions
- Calibrating Instrumentation
1422 Series
The 1422 is a stable and precise variable air capacitor intended for use as a continuously adjustable standard of capacitance. One of the most important applications is in AC bridge measurements, either as a built-in standard or as an external standard for substitution measurements. It is available in a variety of ranges, terminal configurations, and scale arrangements to permit selection of precisely the required characteristics.
- Stability: better than 0.02% full scale per year
- Settable to 40ppm
- Low Temperature coefficient, low losses
- Wide selection to suit needs
- 3 different models

1413 Series
IET continues to produce the 1413 Series Decade Capacitor to the same exacting specs as GenRad. The 1413 is not only a precision standard, it is a systems component as well - connections are made at the rear for this purpose.
Six precision decades are employed to provide a range of 0 to 1.11111µF in increments as small as 1 pF and with an accuracy of 0.05% +0.5pF. Air capacitors are used for the two lower decades and precision silvered-mica capacitors are used for the remainder. The lower four decades contain adjustments that are factory set but accessible for readjustment later if desired.
- 0 to >l µF
- 0.05% basic accuracy
- 6-digit resolution
- 3-terminal connections
- Optional rear-mounted GR-874 locking connectors.

1565-B Sound Level Meter
The 1565-B is a general-purpose sound-level meter that conforms to both national and international standards, meets all criteria necessary for the noise previsions of the Occupational Safety and Health Act ( OSHA ) and includes features found in more cumbersome and expensive sound meters. This meter is also approved for use in gassy coal mines by the bureau of mines.

1531-AB & 1538 Strobotac®
Many U.S. government military and regulatory agencies specifically call out and/or reference these strobes. These products continue to be built and serviced in the Genrad tradition....
These stroboscopes are small portable flashing-light sources used to measure the speed of fast-moving devices or to produce the optical effort of stopping or slowing high-speed motion for observation.
The 1531 is more economical to buy. On the other hand, the 1538 gives you six times the maximum flash rate of the former, and portable operation is possible with a rechargeable battery. The 1538-A can also supports an optional extension lamp.

Model 1539-A
The 1539-A is a cost effective solution when external triggering only is required or when high intensity light is necessary by using multiple units.
The Stroboslave stroboscopic light source satisfies the basic requirements for motion studies and high-speed photography-it produces a bright white light at flash rates up to 25,000 per minute. Since it contains no internal oscillator to establish the flash rate, it is an economical unit and is well suited for use with external inputs.
External triggering required. Can be slaved to the external trigger of the 1531, 1538 or 1546.
An accessories kit is also available, please contact sales for info/assistance...

Strobotac 1542-B
The 1542-B is as easy to operate as an extension lamp but is considerably more useful. Plug in the attached power cord, push the On-Off button, point the light at the action, turn one knob until the visual image of the action slows to the desired rate or stops. That's the sum total of the operation -plug, push, point, and turn!
If you are making accurate rotational measurements, the 1546 offers additional features like a digital display, slave and triggered operation and higher strobe rates.
Flash Rate:
- 180 to 3,800 flashes per minute, adjustable over a single range by a 5-turn uncalibrated control.

1546 Strobotac Digital Stroboscope
The 1546 Strobotac Digital Stroboscope features a large, five-digit LED readout that automatically displays the flash rate in bold, easy-to-read digits. This display eliminates the need to calibrate and read a dial to obtain accurate speed measurements. If your application is simpler, such as observational inspection then consider the 1542-B.
