Product Specifications The HFM11 provides fast, thorough, hand and foot monitoring with class leading reliability and ease of use. Now available with both gas sealed and gas flow detectors. HFM11 Gas flow and gas sealed hand and foot monitor The HFM11 is the latest generation highperformance hand and foot monitor. There are two gas versions: the HFM11GF (gas flow) and the HFM11-SX (gas sealed Xenon). The high-efficiency foot detectors help to reduce monitoring times, the longer hand detectors provide wrist and forearm coverage and there is an optional frisker probe available for additional monitoring. Status, instructions and results are clearly shown on the large color LCD touch-screen, making the monitor especially easy to use. · Low power fan-less operation · Long hand detectors for wrist & forearm coverage · Large touch-screen color LCD display - no keyboard required · Easy to maintain detector assemblies, no tools required · Optional frisker probe · Hex-mesh grills for greater comfort and detector protection · Automated calibration and checking routines The HFM11 is also designed with economy and reliability in mind. The low power consumption means there is no need for a cooling fan which might suck in dust and dirt, and there are no moving parts to fail - solid state Flash storage is used instead of a hard disk in the industrial PC controller, and photobeams are used in the positioning sensors instead of microswitches. The modular ‘X-channel’ platform, with common controller boards and simple cabling, provides for easy, low cost maintenance. It also provides detector intelligence and powerful controller functionality - such as the automated calibration and source checking routines. The X-channel architecture also allows easy retro-fitting of options such as the frisker probe (not available with gas sealed). Gas flow measurement is now handled electronically by on-screen flow graphs and leak and high/low flow alarms. Optional Frisker Sophisticated voltage scanning software included which will clearly display the optimum voltage in order to minimize cross-talk between alpha and beta channels (gas flow) and discriminate between X radiation and other interfering radiations (gas sealed).

All HFMs are factory-tested with reference sources. 100 second rolling average Auto time: 1 to 100 seconds Audible and visible alarms occur if a hand or foot is out of position. Digital screen displays for alpha and beta levels for each hand and foot. Magnitude and type of contamination is displayed (can be suppressed from the set-up menu). Separate indications for ‘Out Of Position’, ‘Clear’ and ‘Alarm’ states, as on previous HFM versions. 0.1 to 10 sigma in 0.1 sigma steps 0 to 10 sigma in 0.1 sigma steps High Voltage, detector response, detector contamination and background level are monitored.
