ORP169E Waterproof ORP Meter Oxidation Reduction Potential Tester Pen for Pools & Aquariums

Ensure accurate water sanitization, chemical balance, and oxidation-reduction monitoring with the ORP169E Waterproof ORP Tester Pen. Engineered for precise liquid diagnostics, this portable digital meter measures Oxidation-Reduction Potential (ORP) across a wide range of $0 \text{ to } \pm1999\text{ mV}$. Designed for swimming pools, hot tubs, aquariums, aquaculture, hydroponics, and water purification testing, it quickly detects the effectiveness of chlorine, ozone, and other sanitizing agents. Featuring a high-contrast digital LCD screen, a protective sensor cap, an easy-to-replace electrode, and an IP65 waterproof housing, the ORP169E delivers reliable, instant water quality analytics wherever you need them.

Key Features

• Wide Range $\pm1999\text{ mV}$ Detection: Accurately measures Oxidation-Reduction Potential to verify water purity, disinfection levels, and sanitizer strength.

• IP65 Waterproof Housing: Compact, pen-style design with full waterproof sealing protects internal electronics during accidental submersion.

• Replaceable Platinum Sensor Electrode: High-sensitivity probe ensures fast response times and can be replaced easily to extend device lifespan.

• High-Definition LCD Screen: Clear digital readout provides crisp visibility in direct sunlight or dim equipment rooms.

• Simple One-Touch Calibration: Built-in trimmer screw allows straightforward manual calibration for laboratory-grade consistency.

Why Choose Our ORP169E Water Tester

Relying solely on pH or basic chlorine test strips fails to measure the actual sanitizing power and oxidation capacity of your water, leaving pools vulnerable to bacteria or over-chlorination. Delicate glass hydrometers and bulky desktop meters are impractical for field testing around water bodies. The ORP169E combines high-sensitivity ORP detection, IP65 waterproof durability, a replaceable probe, and pocket-sized portability—giving your pool maintenance, aquarium care, and water treatment auditing an instant professional upgrade.
