The MP-4 Portable Meter is a cableless, single-handed instrument for rapid testing of conductivity, resistivity, total dissolved solids (TDS), and temperature in clean water applications. Integrated sample cups and one-button operation enable fast, probeless measurements suitable for pool and spa monitoring, water treatment, and field testing.
- Probeless operation with integrated sample cups.
- Measures conductivity, resistivity, TDS, and temperature.
- Temperature accuracy of ±0.1 °C.
- Battery life greater than 100 hours (≈5,000 tests) with auto-shutoff.
- One-button calibration; typical calibration interval two weeks to monthly.
- Automatic temperature compensation; adjustable or disableable.
- User-adjustable conductivity/TDS conversion ratio for nonstandard solutions.
- Data retained in non-volatile memory; waterproof and buoyant-operational after immersion up to 1 m (3 ft).
