Opsytec Radiometer RMD Touch

The Opsytec RMD Touch Laboratory Radiometer is a high-precision digital UV measuring instrument designed for accurate irradiance and dose measurements in laboratory, pharmaceutical, and industrial environments. Developed with over 40 years of UV measurement expertise, it offers advanced touch control, multi-sensor capability, and unmatched stability for a wide range of UV, LED, and photobiological applications. The RMD Touch integrates modern technologies such as a capacitive touchscreen, 24-bit precision ADCs, extensive data storage, and remote firmware updates. It supports simultaneous measurement of multiple sensors for irradiance and dose, making it one of the most powerful multichannel radiometers available today. Each sensor channel includes a high-precision 24-bit ADC with multi-stage amplification, achieving a dynamic range of up to seven orders of magnitude. Measurements across all channels occur simultaneously, while calibration and sensor data are permanently stored and automatically transferred to the device. Its sensors are durable, long-term stable, and suitable for a wide variety of applications. They can be connected not only to the RMD Touch but also to the mobile radiometers RMD and RMD Pro. Applications UV radiometry Low-light detection LED measurements Germicidal UVC and disinfection (UVGI) Optical hazard analysis Lifetime and stability testing Plant photobiology Phototherapy UV curing and exposure control Technical overview Measurement range: up to 7 orders of magnitude Sensor memory: includes identification, calibration history, and temperature sensor Display: high-resolution capacitive touchscreen Processor: ARM Cortex for fast processing and firmware updates Interface: fully digital USB connection Software compatibility: Windows 10 and 11 Units available: W/m² (watts per square meter), µW/cm² (microwatts per square centimeter), J/m² (joules per square meter), lux, and klx Recording capability: up to 1000 days of continuous measurement data directly to a USB stick Construction: robust design for laboratory, pharmaceutical, and industrial use Dimensions (device only): 8.3 x 4.3 x 1.8 in (210 x 110 x 45 mm) Weight: approximately 1.5 lb (0.7 kg) Power supply: 100–240 V AC, 50/60 Hz The RMD Touch can be configured and parameterized directly through its touchscreen or controlled remotely from a PC. Numerical and graphical data displays, oscillograms, and data logging modes (min/max and continuous) are all easily accessible. For laboratories seeking high-end UV measurement precision, flexibility, and ease of use, the Opsytec RMD Touch represents the next generation of digital radiometry.
