Description
Features
- Measurement Capabilities:
- EC: 0.00 to 20.00 mS/cm (milliSiemens per centimeter)
- TDS: 0.00 to 10.00 ppt (parts per thousand, or g/L)
- Temperature: 0.0 to 60.0°C (32.0 to 140.0°F)
- Probe: Comes with the HI76306 or HI763063 two-ring amperometric probe (with built-in temperature sensor), which resists clogging and is easy to clean. The probe has a 1 m (3.3 ft) cable and DIN connector.
- Calibration: Automatic, single-point calibration using standard solutions (e.g., HI70030 for 12,880 µS/cm EC and HI70038 for 6.44 ppt TDS).
- TDS Conversion: Adjustable factor from 0.45 to 1.00 (in 0.01 increments) to match specific solution types.
- Display: Large, multi-level LCD showing primary reading, temperature, and calibration status.
- Power: Battery-operated (typically 4 x AAA batteries, up to 500 hours of use); includes BEPS (Battery Error Prevention System) to avoid unreliable readings from low power.
