MMK 3in1 TDS EC Water Quality Tester Meter for Aquarium Pool Hydroponics Drinking Water Hot Spring Conductivity Blue

---------------------------------------------------------------------- 【Multifunctional 3-in-1 Measuring Instrument】Simultaneously measures TDS, EC, and water temperature in aqueous solutions. EC: 0-9999 μs/cm, TDS: 0-9990 ppm, Temperature: 0.1-80.0℃. The pen-type unit comes with a hard case, making it easy and safe to carry outdoors. [Ultra-fast measurement, high precision] By employing a special alloy electrode, highly accurate measurement results can be obtained the instant the electrode is immersed in the solution. Furthermore, a function that automatically corrects the measurement value according to the solution temperature makes it possible to obtain even more accurate data. [Hold & Auto-Off Function] After the measurement data has stabilized, pressing the HOLD button will lock the measurement results, ensuring reliable reading and saving. Furthermore, even if you forget to turn off the power, the switch will automatically shut off after 5 minutes to prevent battery drain. [Pre-shipment Calibration & 100% Inspection Completed] All products undergo pre-shipment calibration in Japan. Furthermore, only products that meet the measurement value of "0" in the pure water measurement test are considered acceptable and are guaranteed to meet this standard. [Reliable Japanese Manufacturer Quality] We implement strict quality control. In the unlikely event of initial defects, you can rest assured that you will receive replacement or other support in accordance with our standard quality guarantee. TDS & EC Meter
