Inductance standards and decades provide highly accurate and digitally variable standard values of inductance for calibration, comparison and testing.
Capacitance standards and decades provide a highly accurate standard value of capacitance for calibration and testing.
Resistance standards and decade boxes provide a highly accurate standard value of resistance for calibration and testing.
Voltage dividers and voltage references provide highly-accurate reference voltages for calibration and testing purposes.
Environmental test equipment services for environmental test chambers, reactors, baths, incubators, laboratory ovens and furnaces, and vibrational shakers. Services may include repair, calibration, upgrading, rebuilding, installation, training and replacement.

Analog Ammeters

(126 companies)
Analog ammeters are metered instruments that measure current flow in amperes. They display current levels on a dial, usually with a moving pointer or needle.
Boiler services include repair, rebuilding, maintenance and installation of boilers. They may also provide cleaning, calibration, condition assessment, field inspection, failure analysis, and part replacement services.
Decade boxes and dividers provide highly accurate and digitally variable standard values of resistance, capacitance, inductance, voltage and/or current for calibration, comparison and testing.
Color swatches and reference systems consist of a set or palette of chips, swatches or panels with different colors for calibration of color instruments, painting blending systems, and for color selection.
Viscosity standards and reference fluids are oils, fluids, greases, or gels with stable and verified viscosity values and flow properties for calibration of viscometers, rheometers, and other standards.
Masters and setting gages provide dimensional standards for calibrating other gages.

Gage Blocks

...in precision or master calibration gaging operations in temperature controlled metrology or standards laboratories. Grade 0.5 gage blocks under one inch in length should have length tolerances of +/- 1 micro-inches (1 mike or 1 millionth of an inch...
...include quartz oscillators that are periodically updated to the national standard or atomic clock through a GPS signal. NIST offers a remote calibration service (TMAS - Time Measurement and Analysis Service) to help laboratories around the country...

Clamp Meters

(184 companies)
Clamp meters are ammeters that can measure current without the need to disconnect the wires where the measurement occurs. They provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends.

Digital Ammeters

(240 companies)
Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends
