sx811 portable ph meter
    the most cost effective portable ph, suited for industrial and mining factories, power plant, water treatment project, environmental protection industry, etc, especially suited in field and on-site.

◆ 1-3 point automatic calibration, the meter provides calibration guide and automatic checking function.
◆ the meter is able to recognize up to 12 types of ph standard buffer solutions. there are three options of standard buffer solutions: usa series, nist series and chinese series (ch), there is also customer-defined solution calibration.
◆ the meter provides two special modes for pure water and pure water mixed with ammonia. these special modes offer temperature compensation for ph value, especially suitable or the electricity and petrochemical industries.
◆ equipped with calibration solution and portable case and suited in field and on site.
◆ meter meets ip57 rating.
