Feature:1. 7in1 Chlorine Meter: Multi-function water quality tester for measuring pH, salinity, ORP, chlorine, EC, Total Dissolved Solids, and temperature in swimming pools. Accurately measures the residual chlorine levels to keep pool or spa chlorine levels within safe limits.2. Highly Sensitive Probe: Adopts highly sensitive electrode probe, plug-in design, removable and replaceable. Convenient operation, just put the probe into the water for a few seconds, easy to measure the value of FAC (Chlorine) PH, ORP, SALT, Total Dissolved Solids, EC, TEMP.3. High Accuracy: Temperature measurement design also has an automatic temperature compensation function, which can ensure the most accurate measurement for you in the ambient temperature ranges. /F unit conversion.4. Multifunctional Design: LCD display, you can see the measurement data clearly. Support data hold, one button to lock reading function, you can check the data at any time. With automatic calibration, you can restore the measurement accuracy by yourself.5. Wide Applications: Suitable for drinking water, aquaculture, fish tanks, modern agriculture, wastewater treatments, river water quality tests, etc. It can also be used to measure the chlorine content in swimming pools, spas, and hot springs.Specification:Multifunctional water quality tester for measuring pH, salinity, ORP, chlorine, EC, FAC, and temperature in swimming pools.
