Personal X-Ray/Gamma Dosimeter Ambient Dose Equivalent

PM1605BT: Rugged dose monitoring for harsh jobs.

The PM1605BT is a personal electronic dosimeter that measures ambient dose equivalent and ambient dose‑equivalent rate (gamma/X‑rays) in real time. It combines an IP68 enclosure, a 1.5 m drop rating and glove‑friendly controls with Bluetooth® and USB for live monitoring, history download and threshold setup via Polismart® and PC software.

Why organisations choose this dosimeter

• Correct measurement quantity: ambient dose equivalent (and rate) for area/personnel monitoring; dose‑rate up to 10 Sv/h, dose up to 100 Sv.
• Built for extremes: IP68; −30 °C to +65 °C; 1.5 m drop; up to 98 % RH (at 40 °C); designed to withstand exposure to sea water.
• Clear alarms & display: visual, audible and vibration alarms with a large, easy‑to‑read LCD.
• Connected workflow: Bluetooth® 4.0 to Polismart® (iOS/Android) and USB to PC for real‑time viewing, history download and threshold setup.
• Long life: runs on 1 × AA (1.5 V) with ≥ 9 months typical battery life; external power via USB supported.
