Handheld Gamma–Neutron Detector

Fast gamma search, real personal dose control

The PM1703MO-II BT is a gamma personal radiation detector and dosimeter built for frontline patrols, customs lanes, scrap yards, and CBRNe teams. A high-sensitivity CsI(Tl) search channel plus a GM tube for Hp(10) dose gives you both “find it fast” and “what did I get?” in one device.

With modular hardware, USB connectivity, and the Polismart® companion app, you get an end-to-end workflow from live search to GPS-tagged exposure records and central reporting.

Why Teams Choose PM1703MO-II BT?

• Fast interdiction: 0.25 s response and high-sensitivity CsI(Tl) search channel: quickly walk onto illicit or misplaced sources.
• Real dosimetry: GM tube up to 200 mSv/h and 10 Sv dose: one device covers search and personal dose tracking.
• Rugged build: IP65 housing, −40 to +50 °C and up to 98% RH: ready for ports, tarmacs, yards, and roadside checks.
• Simple UX in the field: 0–9 threat scale, audio and vibration alarms, belt carry: low training burden for mixed teams.
• Connected workflow: USB + Bluetooth with Polismart® app: GPS logging, cloud sharing, and standards-based data export.

Frequently Asked Questions

What radiation does the PM1703MO-II BT detect?

It detects gamma radiation (and X-rays in the same energy band) using a scintillation detector for search and a GM tube for accurate Hp(10) dose-rate and integrated dose. There is no neutron channel; for gamma–neutron, you’d step up to the GNA-II variants.

How rugged is the device for outdoor and industrial work?

The instrument is IP65 rated, operates from −40 to +50 °C and up to 98% relative humidity, and uses a shockproof sealed housing designed for drops and vibration typical of field, port, and transport environments.

Which devices and apps does it work with?

PM1703MO-II BT connects to Windows PCs via USB using Polimaster’s user software, and via Bluetooth 4.0 to the Polismart® app on compatible iOS and Android smartphones for live readout, GPS logging, and data export.

What standards and approvals does it follow?

The PM1703MO-II BT is designed against ANSI N42.32 and IEC 62401 PRD performance standards, and its history files follow the ANSI N42.42 data-format concept, supporting interoperable reporting and evidence packs.

What exactly is included when I order?

A typical kit includes the PM1703MO-II BT unit, belt clip or holster, AA battery, USB cable, PC software access, documentation, and a factory calibration/test certificate; local distributors may add carry cases or accessories.

Compliance note: End users are responsible for ensuring local regulatory approvals, calibration intervals, and export/import controls are met before field deployment or cross-border shipment.
