Dose Calibrator with Bluetooth Remote Display for Hot Cell Use

The Dose Calibrator with Bluetooth Remote Display eliminates the need for cables connecting the hot cell detector to the external display. Traditional dose calibrators require a shielded cable to pass through the hot cell wall, creating a potential penetration in the lead shielding and complicating installation. This instrument uses Bluetooth wireless communication between the detector inside the hot cell and the display unit outside, operating at a range of up to 10 meters. The detector is battery-powered and sealed, requiring no external connections. Installation involves simply placing the detector inside the hot cell and pairing it with the display. The wireless design simplifies retrofitting of existing hot cells, reduces installation costs, and eliminates cables that can become contaminated or damaged.

The Bluetooth Dose Calibrator is designed for nuclear medicine departments that want to add dose measurement capability to existing hot cells without drilling ports or running cables. Primary applications include upgrading older hot cells that lack dose calibrator connections, adding dose measurement to temporary or mobile hot cells, and equipping multiple hot cells with dose calibrators that share a single display unit. The instrument is equally suitable for primary dose preparation workflows, quality control testing, and research applications. The wireless design is particularly valuable for hot cells in hard-to-reach locations, such as those installed in mobile vans or temporary structures.

The Dose Calibrator with Bluetooth Remote Display delivers measurement accuracy of ±5% — equivalent to wired instruments — while providing the flexibility of wireless operation. The Bluetooth connection uses version 5.0 with 128-bit encryption, ensuring reliable communication even in electromagnetically noisy environments (such as PET centers with cyclotrons and imaging equipment). The connection range of 10 meters is sufficient for most nuclear medicine settings, allowing the display to be positioned at a comfortable workstation while the detector remains inside the hot cell. The detector unit is self-contained, with an internal rechargeable battery that provides 8 hours of continuous operation or 40 hours of standby time. The detector charges wirelessly through the hot cell wall (via inductive charging) or can be removed for wired charging during off-hours. The detector enclosure is sealed to IP67 standards — dust-tight and water-resistant — allowing it to be decontaminated by spraying or wiping without damage. The ionization chamber uses the same high-sensitivity design as wired instruments, with a measurement range of 0.1 μCi to 5 Ci and a response time under 5 seconds. The remote display unit is a dedicated 7-inch tablet that pairs exclusively with the detector. The tablet shows the measured activity in large digits, along with the selected isotope, geometry, range, and battery status. The tablet includes the complete dose calibrator user interface: isotope selection from a library of 20+, geometry selection (vial/syringe/capsule), auto-ranging, background subtraction, and data logging. The tablet stores up to 1,000 measurements in internal memory and can export data via USB or WiFi to laboratory information systems. For departments with multiple hot cells, a single tablet can be paired with up to four detectors, switching between them as needed. This allows the department to equip all hot cells with dose measurement capability while purchasing only one display unit — a significant cost saving. The Bluetooth connection also enables remote monitoring: the tablet can be positioned up to 10 meters from the hot cell, allowing measurement results to be viewed from a control room or break area. For nuclear medicine departments, the primary benefit of the Bluetooth design is installation flexibility. Adding a wired dose calibrator to an existing hot cell often requires drilling through lead shielding, which is time-consuming and risks compromising radiation protection. The wireless design requires no modifications to the hot cell — simply place the detector inside and pair with the tablet. The battery-powered operation eliminates the need for electrical penetrations, further simplifying installation. For departments that frequently reconfigure their hot cell layouts, the wireless detector can be easily moved to different cells as needs change. The Bluetooth Dose Calibrator offers a practical solution for departments seeking to add or upgrade dose measurement capability without the cost and disruption of wired installation.
