Personal Portable Dose Rate and Survey Meter [Radiagem 2000]

The Radiagem™ 2000 features excellent ergonomics such as easy handling, large custom LCD display, semi-log bargraph, average digital reading, and visual and audible alarms.

Radiagem's external smart probes extend the capabilities of the instrument to a range of general surveying applications. The probe is a fully integrated subsystem, taking and transmitting the measurement to the instrument, which is used for display. In this "smart" design, key components of hardware circuitry (high voltage, amplifier, discriminator, etc.) are located directly inside of the probe housing rather than in the host survey instrument. Also, the intelligence associated with controlling those components is located in the probe – that is, control and storage of key parameters, settings, calibrations, probe ID, alarm settings, etc.

With high voltage and digitization of the data occurring in the probe rather than the instrument, measurement quality is no longer dependent on cable quality as with older analog systems. Also, the probes can be plugged in "hot" without powering down the instrument – the Radiagem immediately recognizes the probe and automatically switches measurement mode to the mode required for that specific probe.

Calibrations and QA measurements can be performed directly with the probe, without even using the instrument, by connecting the probe to a computer with Radiagem calibration software, allowing your Radiagems to remain deployed in the field.

A data-logging button allows the user to store up to 1000 date stamped data points in probe memory for external probes and in Radiagem memory for the internal dose-rate display (see probes' specifications).

A scaler/timer mode can be used for data-logging with 1 to 255 seconds acquisition time. The Radiagem 2000 firmware can be upgraded via PC serial link with the appropriate cable.

The Radiagem 2000 LCD display includes a large choice of units depending on the probe specification: c/s, Bqeq, Bqeq/cm2, Sv/h and Sveq/h.

Radiagem is also part of the emergency kits that include a variety of contamination probes.
