- pH/ORP Sensor protective cap
- Memory for 20 readings
- Display prompts for simple pH calibration
- Temperature compensation
This meter has a reading accuracy of ±1%, which has been achieved through advanced four-electrode conductivity cell technology, a unique pH/ORP sensor and powerful microprocessor-based circuitry. Four-digit LCD reads up to 9999ms/ppm. Factory calibrated with NIST traceable solutions, this Ultrameter can be supplied with both certification of traceability and NIST traceable solutions for definitive calibration. A single-point calibration simultaneously adjusts all three parameters to 1% accuracy. Meter has fully automatic temperature compensation of 0-71°C/32-160°F, and auto shut-off extends the life of the single 9V battery to more than 100 hours/5000 tests. This microprocessor provides data back-up, even when the battery is changed. This assures all calibrations and memory data will be retained. Meter features user adjustable temperature compensation of 0-9.9%/°C and user adjustable conductivity/TDS conversion ratio of 0.20-7.99 for greater accuracy.
