An advanced hand held digital radiation monitor with a range of probe options for all your contamination monitoring and radiation protection requirements

Radhound X/E is an advanced digital hand held general purpose radiation monitor, suitable for a wide range of probes.

This feature packed instrument boasts unique features, such as the ability to switch between probes via the menu, allowing for example, a dose rate probe and a contamination probe to be configured for use with one instrument. This flexibility allows any standard probe to be used (300-1200V).

Radhound X/E is capable of measuring dose rate, CPS, CPM, Bq/cm2 with alpha and beta discrimination. The instrument menu allows adjustment of thresholds, high voltage, dead time and over-range protection.

Simple and easy to use

We take great care to ensure our instruments are very easy to operate. The menu on the Radhound X/E can easily be locked by the user to ensure only basic options are available, giving greater security and protection against accidental setting changes.

Multiple probe library/confirguration

As well as operating as a traditional single probe instrument, the Radhound X/E allows the user to switch quickly between alternative probe setups. (The user is instructed to plug in the correct probe before the new settings are applied, protecting against possible over voltage or use of incorrect settings).


Radhound X/E has an adjustable alarm threshold. Additionally separate alpha and beta alarms can be set. The sounder is loud and clear, and is suitable for use in many different environments. A symbol flashes on the display when in alarm.

Scaler Timer

Radhound X/E has a scaler time mode, allowing the integration of count for a preset time (or time to a preset count). Additionally in dose rate mode, time to dose can be indicated.

Self Test

Radhound X/E automatically checks its health on turn on. It checks the high voltage, battery level, keyboard and sounder.

Probe Cable

A curly probe cable is provided with the Radhound as standard and is fixed at the monitor end.

No probe cable is provided with the Radhound X as this will depend on customer preference. A 1 metre straight cable is recommended for most applications, however, different lengths and types of cable, such as coiled cable, are available. We can also provide quantity numbers of probe cables to order.

Data Transfer Options

Wired Serial Socket

An RS-232 port can be added to the Radhound or Radhound X to allow connection to a Windows-based PC or tablet. Measurements can be transferred in real time and displayed on the screen through a simple communications protocol. This data can then be saved in a .csv format. A straight through 9 way female serial connector must be used, which is not included. Please be aware that adding this port removes the weatherproof status of the Radhound X.

Infared Serial

The Radhound can be fitted with an internal infrared transmitter to send data without the need for a wired RS-232 serial port. The IR transmitter can transfer measurement data in one direction only, over a line-of-sight distance of up to 1 metre. An IR receiver is included with the purchase of this option, which plugs into the USB drive of a Windows based PC or tablet, to pick up real time data transmission from the meter.All contamination probes are tested against our in-house sources and are provided with a basic test certificate, confirming that the probe response to radiation is within the expected limits.

Instrument Cases

Rugged travel cases are available in sizes to suit your application. These are genuine Peli Cases, which offer unrivalled protection for your equipment. They have foam inserts which can be customized to fit which ever probes you require.

Connector Type

Please specify with your order which type of connector you would like to be used for your probe and meter. MHV connectors are now the most common for handheld devices and are used for our products as standard. Some older instruments use PET or BNC type connectors, which we can fit by request, but please note that some of these older types are not recommended due to safety concerns.

Southern Scientific have produced a number of prefabricated radiation protection kits, for use by radiation workers.

Each kit offers a significant saving over purchasing the individual instruments, as well as having the advantage of being packaged inside a rugged travel case.

If none of the kits are right for you, then please get in contact with us and we can discuss your individual needs and come up with a suitable solution.
