This digital pen style meter is an ideal instrument for any aquarium, the fishing industry, swimming pools, school laboratories, food & beverage, etc. And, this Digital TDS Water Quality Tester is ideal for all basic water testing applications. This product is highly efficient and accurate due to its advanced microprocessor technology. Hold Function: stores measurements for convenient reading and recording. Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Measurement Ranges is between 0-9990 ppm, and from 0-999 ppm, the resolution is in increments of 1ppm; from 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image. Specifications: Fast measuring: can measure once in five seconds Accuracy: ± 0.1PH (at 20) Battery: 2x 1.5V (CR1620 button battery,included) Relative Humidity: <95 Working temperature: 0 - 50 Zero: Adjust by the compensate potentiometer Through the EU CE and ROHS certification Size(L*W*H):15*2.40*1.70cm/5.91"80.94"*0.67" Note: The value of TDS can show the content of impurities. The bigger of the value means that the content of impurities is larger; conversely, the content of impurities is small. The factors that affect the test value of TDS: the temperature of water (the TDS-3 tester cannot test the water with high temperature such as, boiled water). The flow velocity of water (the TDS-3 tester cannot be applied to test the flowing water) If the tester displays a flashing "X10" icon, multiply the reading by 10 Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon. And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
