SX825 portable pH/dissolved oxygen measuring instrument
SX825 portable pH/dissolved oxygen measuring instrument
Product details
1、 Product features:
| ♦ Multi parameter instrument, equipped with pH electrode, conductivity electrode, and dissolved oxygen electrode, with automatic identification of electrodes by the instrument. |
| ♦ Automatically identify 12 pH standard buffer solutions, with three series of standard buffer solutions to choose from. |
| ♦ Pure water pH measurement mode and ammonia added pure water pH measurement mode can be set to perform temperature compensation on pH value, suitable for use in industries such as power and petrochemicals. |
| ♦ The dissolved oxygen electrode is equipped with a temperature sensor and a salinity sensor. The dissolved oxygen measurement mode has the functions of automatic temperature compensation, automatic salinity compensation, and manual pressure compensation, making the measurement more accurate. |
| ♦ Polarographic dissolved oxygen electrode, equipped with a dedicated electrode calibration kit, electrode polarization only takes 3-5 minutes; The electrode is equipped with three combined diaphragm caps, making it very convenient to replace the oxygen permeable membrane. |
| ♦ Configure calibration solution and carrying case, suitable for field and on-site use. |
| ♦ The instrument meets the IP57 waterproof rating. |
