Digital Water Quality Testers, TDS Total Dissolved Solids Meter Testing Pen Water Purity Measuring Tools TEMP/PPM Testing for Drinking Water Hydroponics Pools
【Testing more accurate and convenient】Hold automatic locking function makes the water quality pen easily to read and record; automatic temperature compensation mode to water quality test more accurate; accuracy error range is as low as ±2%.
【Wide range testing】TDS meter measuring principle is to measure the electrical conductivity of water and indirectly reflects the TDS value. TDS ranges from 0~9990ppm(parts per million).
【Auto-off function】Automatic power-off function allows it to power off after 5 minutes without any operation in order to save power. It supports hold function that can save measurement results for easy reading and record.
