An ergonomically balanced handheld built on Symetrica's patented, field-proven Discovery Technology®. It pairs simple color-coded isotope classification with high accuracy radiation detection and identification, and with GPS plus Wi-Fi, 4G and USB it gets the result to the people making the call.
Symetrica states that its advanced algorithms improve the effective resolution of the gamma detection system, for reliable low-level detection and fast, simultaneous identification of multiple and masked isotopes in challenging real-world environments.
Schematic illustration, not measured data. Discovery Technology uses on-board processing for spectral enhancement.
Discovery Technology® is a combination of Symetrica's hardware and patented algorithms. Symetrica reports it is deployed in thousands of systems globally, from handheld RIIDs to fixed Radiation Portal Monitors (RPM), and is the current technology of choice (through competitive evaluation) of multiple US and international government agencies. Per Symetrica, on-board spectral enhancement backed by its analysis of real-world data results in:
A 3 button keypad optimised for use with one hand, gloved, and a color, transflective active matrix LCD. Here is how a survey runs.
Fast start-up, and Symetrica states the unit can switch on and operate in high radiation fields.
With continuous operation through temperature shock. Dose rate from 1 nSv/h to 900 mSv/h (1 μrem/h to 90 rem/h).
Simultaneous ID of multiple and masked isotopes. Sampling time is user settable from 30 s to 60 mins.
Simple color-coded isotope classification from a customizable library that exceeds ANSI N42.34.
Email instant and automatically generated reports over Wi-Fi or 4G (Bluetooth optional), from a unit with in-built GPS.
Ergonomically balanced, comfortable for prolonged use. 1 spare battery is provided as standard.
The S200 is available with a choice of gamma crystal and several optional extras. Tell us how you will use it and we will confirm which configuration to quote.
1.5 x 1.5 in (38.1 x 38.1 mm) crystal with Discovery Technology. Tell us which you need when you request a quote.
The optional neutron detector uses 6Li:ZnS technology, which Symetrica says also achieves class-leading sensitivity.
PDF reports, ANSI N42.42 compliant. Reach-back fleet features are options.
COTS replaceable, rechargeable Li-ion battery with 1 spare battery provided as standard.

Request a quoteThe S200 runs automatic and continuous end-to-end digital calibration, stabilization and health monitoring. Symetrica lists this under high reliability, with no annual calibration required.
It is not maintenance-free: there is a 5-year calibration and service interval, and predictive maintenance is among Discovery Technology's results. Plan the fleet around that interval.
Fully functional and accurate operation through temperature shock, with continuous operation and instant response to sources.
Switch on and operate in high radiation fields. The scintillator range carries automatic scintillator shutdown protection, and a High Dose Rate Mode covers higher fields.
Health is visible beyond the handset: Symetrica's reach-back webserver software provides remote diagnostics, remote settings and software updates for connected devices.
OEM-certified service and support on every product we deliver. When a repair or calibration falls outside our in-house scope, we coordinate directly with the third-party manufacturer and manage the logistics end to end.
Repair DepotA fully connected smart device. Symetrica designed its real-time connectivity so the information required for critical decisions is immediately available to experts, with reach-back from multiple locations.
Remote, real-time monitoring of in-the-field devices, including events lists and dose mapping. Real-time dose mapping and unit tracking at reach-back is optional.
Remote settings, software updates and remote diagnostics through Symetrica's reach-back webserver software. Remote view and/or operation of in-the-field devices is optional.
Instant and automatically generated reports by email, with in-built GPS and wired and wireless options including Wi-Fi, 4G and USB.
Symetrica states the design lends itself to quick and easy mounting and de-mounting on both manned and unmanned platforms.
