The HI98304 DiST® 4 is a sleek, pocket-sized conductivity tester that delivers quick and accurate measurements up to 20.00 mS/cm. Slim and ergonomic at only 17 mm (0.7″) thick, it fits comfortably in your hand. With just two buttons for On/Off and calibration, operation is refreshingly straightforward. The meter features a large LCD that displays both conductivity (with 0.01 mS/cm resolution) and temperature simultaneously, while an exposed temperature probe ensures fast, auto-compensated readings. Its graphite electrode resists oxidation for better repeatability, and it automatically calibrates with a single tap. Rugged and reliable, it’s perfect for field or lab use. manischemicals.com+8hannainst.com+8hannainst.com+8
