Inovision 451P X/ϒ Radiation Dose Survey

The autorange 451P employs a pressurized ionization chamber, offering higher sensitivity (μR resolution) and better energy response for detecting dose rate and dose from X-ray and gamma sources. Originally designed to diagnose leaky and scattered radiation around X-ray and radiotherapy equipment, the 451P's superior field survey capabilities have broad applicability across various fields, including X-ray equipment manufacturers, government oversight agencies, biomedical technicians, and maintenance personnel for airport package scanning equipment.

The ionization chamber detector provides the instrument with a fast response time to leaky, scattered, and diffracted radiation. Furthermore, the low-noise ionization chamber bias ensures rapid background stabilization.

The display features an analog bar graph pointer, a 2.5-digit digital reading, low battery and freeze mode indicators, and automatic backlighting. User controls include an ON/OFF button and a MODE button. The instrument is constructed from lightweight, high-strength materials and is sealed against moisture. The RS-232 interface allows direct connection to a computer to utilize the Windows® (451EXL) Excel add-in, enhancing the instrument's functionality. This software enables data retrieval, user parameter selection, and provides a virtual instrument display with sound (sound card required) and visual alarm indicators.
