Electrical Calibration
Littlebrook Calibration specializes in DC/AC Standard Resistance calibrations of a very high Accuracy up to ±0.35 ppm, in some cases bettered only by the National Physical Laboratory at Teddington, where we obtain our Traceability. Calibrate different instruments used in various industries like pharmaceutical, power stations, NHS industries. Calibration specialist in shunt resistors, and decade resistance box up to Tera Ohm.
In addition, Littlebrook has a wide range of Calibrations for the entire spectrum of BS7671/16th & 17th Edition Wiring regulation compliant test equipment, multi-function testers, RCB, Loop, PAT, Earth, AC/DC clampmeters,T/C metal thermocouple & resistance thermometer Pt100, Low Ohmmeter and Insulation testers.
