The Transmille 9000 Series is a high-performance transportable multiproduct calibration system engineered to be the mainstay of a modern working laboratory, capable of calibrating over 18 types of instruments . Designed for both on-site and laboratory use, it meets the demands of quality protocols like ISO9000 and ISO17025, and can be supplied with a UKAS calibration certificate traceable to National Standards .

Two models are available: the 9041 offers 25 ppm accuracy and can calibrate up to 7.5 digit multimeters, while the 9050 provides 50 ppm accuracy . Both models feature an ultra-linear VMOS power amplifier that provides 30A capability (9041), with continuous output available up to 20A . Direct Digital Synthesis (DDS) technology generates stable, jitter-free wideband AC waveforms, while two-stage cooling reduces thermal EMFs for enhanced precision . DC voltage ranges from 0 to ±1000V with ±25 ppm accuracy, and resistance measurement is available up to 1GΩ on the 9041 model .

The system's versatility is extended through a unique system of add-on external calibration adapters that dramatically increase its workload . Options include dry block temperature calibration modules (25°C to 200°C, ±1°C accuracy), oscilloscope calibration up to 600 MHz bandwidth, RTD/PRT simulation, thermocouple simulation with ±0.09°C accuracy, and power calibration options . Safety is paramount, with the I-GUARD system preventing output from being switched on if voltage is detected on the terminals .

The rugged enclosure with integrated castors and a retractable handle makes it easy to transport, and its fast warm-up time ensures quick and accurate calibration in the field—30 minutes to full accuracy, with 90% of specifications achieved within 10 minutes . The 9000 series is designed for industrial environments including off-shore, aerospace, and military applications, and is fully compatible with ProCal calibration software for automated procedures . A USB interface is provided for direct PC connection, with RS232 serial interface standard .
