Portable Pen-Style ORP Meter with 3-Color LED Indicator

Short Description:

This product is a pen-style ORP (oxidation-reduction potential) gradient meter featuring a portable pen-style design that provides long-lasting power with a single 1.5V battery. Through three LED indicators—red, yellow, and green—the product displays the ORP value of the tested solution in graduated levels, allowing users to quickly assess the solution’s oxidation-reduction state without needing to take a reading. The device has extremely low standby power consumption and is simple to operate (single-button control), making it widely applicable in aquaculture, swimming pool water quality monitoring, water treatment, laboratory screening, and rapid on-site testing.
