Laboratory-Type Accuracy in a Battery-Operated DC Calibrator

Vitrek offers the XiTRON 2000 series for metrologists who need superior accuracy and portability when calibrating thermocouple, pressure, flow and DC instrumentation. Delivering laboratory-level accuracy in a battery-powered DC calibrator, the 2000 Series is a cost-effective calibration/simulation tool ideal for applications spanning the consumer, medical, automotive, process control and many other industries.

The high-performance 2000 Series computes current or voltage output using an equation derived from two data points to simulate the sensor output. Automatic cold junction compensation is included, allowing both measurement and simulation of values in °C or °F for B, E, J, K, N, R, S and T thermocouples. Additionally, current loop (4-20mA) indicators, controllers and recorders can be precisely calibrated with accuracy measured in parts-per-million (ppm) rather than percentages.

Key features of the XiTRON 2000 Series DC calibrator include:

·        DC voltage and current capability, +/- 22 volt, 10ppm accuracy, +/- 22mA,40ppm accuracy

·        Temperature simulation with 0.01^o resolution, 0.015^o- 0.12^o accuracy (90 day)

·        DC resolution down to 10nV or 10pA

·        Temperature measurement with 0.1^o-0.2^o accuracy (90-day)

·        Auto cold junction compensation NiMH battery operation (8 hours typ.)

·        Standard RS232 interface allows laptop PC control in the field, while the optional IEEE-488 interface supports ATE applications

·        Additional memory can be added to either interface for 10 user-defined test steps

·        Temperature control loops

·        Thermocouple measurement and simulation
