Handheld Luminescent Optical Dissolved Oxygen Meter from the Makers of the Worlds 1st Commercial Luminescent optical DO Sensor



Environmental Instruments, LLC is proud to introduce their Patented Model FL-3-H handheld dissolved oxygen meter. There are no membranes or electrolyte and the sensor is not damaged by direct or indirect sunlight. It is the fastest responding handheld D.O. sensor on the market. The keypad functions are simple to use and the ABS instrument enclosure is waterproof, dust proof, chemical resistant and floatable.

Enviromental Instruments introduced their first commercial luminescent/optical dissolved oxygen controller sensor to the market in 1997 and that sensor is still in operation today. The Patented technology has single handedly changed the way that dissolved oxygen is measured throughout the world. Applications for the FL-3-H handheld meter include, water, wastewater, aquaculture and other aqueous solutions.
