Using UV fluorescence technology, the TD-120 can detect hydrocarbons with superior accuracy, ranging from <1 PPB up to 6000 PPM. Spare parts are readily available, reducing downtime—a key advantage over the SERES Opal, where users often struggle with parts access. Unlike Opal’s infrared method, TD-120 measurements remain stable even in turbid water, minimizing interference. With its compact, corrosion-resistant design, easy calibration, and low maintenance costs, TD-120 is the clear choice for dependable performance and environmental compliance.
