Cub 11.7 eV

Personal VOC Gas Monitor

The Cub 11.7 eV personal VOC gas monitor is worn within the breathing zone to detect volatile organic compounds, keeping you safe within your working environment.

Our personal VOC gas monitor is the worlds smallest and lightest wearable VOC gas detector. When worker exposure exceeds pre-set limits, the gas monitors audible, vibrating, and flashing LED alarms alert you to the VOC gases present. Readings are displayed on its bright, back-lit LCD display with selectable data logging time.

Cub’s patented photoionisation detection (PID) sensor technology has been independently verified as best performing for speed, accuracy, and humidity resistant operation.

Our personal VOC gas monitor is the world’s smallest, lightest personal PID monitor for the accurate detection of volatile organic compounds and other gases that require a higher energy output such as acetylene, methanol and formaldehyde.

Also available from ION Science, the Cub 10.6 eV personal VOC gas detector & the Cub TAC benzene detector.
