8508A 8.5 Digit Reference Multimeter

The 8508A is an 8.5 digit resolution designed specifically for metrology applications, and serves as a versatile and precise measurement tool for calibration laboratories that are required to meet strict measurement uncertainty analysis requirements (ISO 17025).

The unit is capable of replacing 8 other measurement devices including multimeters, resistance bridge, voltage divider, null detector, ac/dc transfer standard, precision thermometer, ac/dc shunt resistors, and electrometer/pico ammeter. The unit delivers 365 day stability as low as 2.7ppm, with 24 hour stability of 0.5ppm. DC and AC ranges from 200 mV to 1 kV to cover all voltage needs. Bandwidth for AC measurements extends to 1 MHz.

Features include current measurement with ranges from 200 µA to 20 A and frequencies from 1 Hz to 100 kHz. Resistance measurement with ranges 2 Ω to 20 GΩ and resolution as low as 10 nΩ, and high maximum compliance voltage of 200 V. Temperature measurement through 2, 3, or 4-wire PRT’s or SRPT’s with temperature range from -200°C to 660°C.
