QWO Online sensor

Engineered for High UV Intensity

The QWO Online Sensor is specifically engineered for reliable UV medium-pressure lamp monitoring under demanding conditions. Its robust design ensures long-term stability even at high UV intensity and elevated temperatures, where conventional sensors typically drift or degrade. With a proportional output signal of DC 0–10 V, the sensor can be seamlessly integrated into machine control systems. Sensitivity is adjustable up to a factor of 1000 and can be fine-tuned in steps of 0.3, offering flexible adaptation to various application requirements. Easy to handle, durable and precise, the QWO Online Sensor provides dependable UV measurement performance for continuous operation.
