Residual chlorine meter main unit EW-521 1 piece

It uses a flat electrode that is easy to clean. No reagents are required during measurement, allowing for low-cost measurements (reagents are required during calibration). Equipped with pH measurement and automatic pH correction functions. Measurement range: CL sensor/0.00 to 2.00 mg/L, pH/2.00 to 12.00 pH Measurement method: CL sensor/galvanic method, pH sensor/glass electrode type Sensor electrode: CL sensor/platinum, silver chloride, silver, pH sensor/glass electrode, gold Water temperature measurement range: CL sensor/5.0-60℃, ph sensor/0-60℃ Measurement time: Approximately 15 seconds pH range: 5.8-8.0 Conductivity range: 50 to 1000 μs/cm Functions: Calibration function (0.30 to 1.50 mg/L), auto power off 10 minutes (after last button operation), temperature display function, memory function, battery level detection function, automatic pH correction function (when measuring CL) Power supply: DC6V AAA alkaline (LR03) batteries x 4 (included for testing) Size: Main unit: 202 x 82 x 37 mm, Sensor: φ12 x 160 mm Weight: Approx. 260g (including batteries) Accessories: CL sensor (EW-521CS), pH sensor (EW-521PS), DPD reagent simple set (color chart, container, 2 packets of reagent x 5), powder for pH standard solution (pH 4.01, 6.86, 9.18 x 1 packet each), strap, connector protection cap, sensor holder *If the water being measured is different, calibration is required each time. *Cold springs, hot springs, mineral springs, well water, and alkaline ionized water cannot be measured. *Do not immerse in liquids with a pH level exceeding 60°C.
