Our legionella monitor measures the temperature of water pipes, detecting any fluctuations or hot spots that may indicate the presence of legionella bacteria. Legionella can grow and reproduce in hot, stagnant water and humid environments and is responsible for legionellosis, a serious respiratory disease. Our monitor continually measures the temperature in pipes, alerting you to any unusual spikes or decreases immediately. Our Legionella monitors come in single probe, dual and triple probe for various applications.

Our legionella submersible probe monitor provides a reliable, real-time measurement of water temperature and potential legionella levels in your water systems. The probe is completely waterproof and submersible in water, allowing it to measure temp and potential  legionella directly where it's most likely to affect your water system. The monitor is designed to provide accurate and consistent measurements, and it does not require battery replacement or calibration. With our submersion monitor, you can rest assured that your systems are compliant.
