Hotec HTC-203U Handheld Resistivity/Temperature Meter User Manual
The HTC-203U is a handheld microcomputer resistivity/temperature meter that measures resistivity from 0.0 to 20.00 MΩ and temperature from 0.00 to 99.9 °C. It features automatic temperature compensation, a single PRC‑10 composite electrode usable from ultrapure water to seawater, and adjustable temperature‑coefficient settings via the front panel.
Before measuring, verify the instrument is calibrated, insert the PRC‑10 electrode, turn the power on, and follow the step‑by‑step procedure: avoid EMC interference, immerse the electrode, stir gently to release bubbles, allow the sensor to stabilize, and read the value. After each measurement, rinse the electrode with tap water, dry it, and perform a recalibration if needed. The manual also outlines warranty terms and safety precautions. This manual is written in Chinese.
