Extech RE300 ExStik ORP Waterproof Meter

The Extech RE300 ExStik ORP Waterproof Meter is a compact and durable device designed for reliable oxidation-reduction potential measurements. It works effectively across liquids, semi-solids, and solids, making it ideal for lab and fieldwork. With a rugged, waterproof IP57 casing, this handheld tool floats and withstands harsh environments with ease.

Advanced ORP Measurement Technology

Using a platinum flat surface electrode, the Extech RE300 ExStik ORP provides consistent and precise readings. The built-in reference junction enhances measurement stability. A bright digital display and simulated analogue bar graph present readings clearly, helping users visualise changes over time.

User-Friendly with Practical Features

The device includes auto self-calibration and a data hold function. It can store 15 readings in memory and retains the last calibration value for convenience. The Extech RE300 ExStik ORP also features a low battery indicator, auto shut-off, and data validation to confirm stable readings before logging.

Electrode modules can be replaced easily and are suitable for extra pH and cleaning probes. The RE300 automatically detects which probe is attached, making sure the setup is correct every time. Accessories like extension cables and a heavy base enhance its flexibility further.

Key Features
  • Measures redox levels in mV
  • Platinum flat surface sensor ensures accuracy
  • Stores 15 readings and saves last setting
  • Automatic self-check for easy setup
  • Simulated display bar shows changes
  • Data hold and auto shut-off feature
  • Waterproof IP57 body floats on water
  • Sensor part is easy to replace
  • Works with swap-in ExStik probes
  • On-screen signs confirm reading stability
