The Wide-field X-ray Monitor on HETE-2 consists of four Xe-filled 1-D position-sensitive proportional counters. It is sensitive to X-rays between 2 keV and 25 keV, and is designed to localize gamma-ray bursts in real time with $\sim10^{\prime}$ accuracy. The design and basic characteristics of the detectors are presented.

Key words: instrumentation: detectors -- gamma-rays: bursts -- X-rays: general
