The new HF scientific HF-38 Fluorimeter is an extremely sensitive, hand-held, ruggedized instrument designed for field testing of toxic heavy metal contaminates in water supplies. It requires no special skill or knowledge of chemistry to operate. The HF-38 is a breakthrough in efficiency, testing accuracy and ease of use and is designed for use with HF heavy metal sensors. Through the use of DNA sensors, a reaction that fluoresces in the presence of a target contaminate substance, such as lead, is measured to determine the concentration of the target heavy metal and is reported in parts per billion (ppb).
