Abstract：
HIRFL magnetic field measuring system was built in October, 1983. There are 94 Hall probes on a detecting arm. The positioning device, which mainly consists of a detecting arm, a rotating ring and a fixed ring, is of a polar coordinate type. For 16KG magnetic field, the measuring repeatability of the system is better than ±5×10^－5, the measuring accuracy is about ±1×10^－4. The measuring rate is about 188 data per minute.
