  • Standard COD digestion instrument reflux HJ828-2017 of national patent technology products, in line with GB patent No: ZL200920023740.1
    2011 Green environmental monitoring instruments finalists
    2012 annual Jinan independent innovation products (included in the government priority procurement plan)

    Instrument Description:
    Chemical oxygen demand (COD) is surface water, industrial wastewater, sewage and other projects will test the waters, it is an important indicator reflecting the status of water contaminated ozone-depleting substances, but also the implementation of key indicators of the country's total emissions control One. The "Water dichromate COD Determining Method" (HJ828-2017) is widely recognized as the most accurate and reliable measurement result of the detection. But water sample digestion process is a reflow temperature and time control more stringent process control is not good cause the results to vary.
    I launched the company with reference to HJ828-2017 This instrument method. PID temperature control to high-power electric heater instead of heating furnace, instead of the condensed water with air cooling, a start key, automatic temperature control, micro-boiling automatic countdown state 120 minutes, the end of automatic shut-down digestion technology to achieve a method of operation GB echo wears, a key operation, automatic digestion, energy saving, easy to use and easy to operate, while avoiding the non-GB technical disputes arising measurement of COD.

    Main technical specifications:

    • Digestion member: Digestion hole graphite cast material, digestion is the number of holes 12, a single hole can be controlled;

    • Heating elements: the integration of independent winding design the heating mode, the respective heating hole digestion thoroughly heated evenly;

    • Cooling: air-cooled reflux condenser unique design, mushroom top design to facilitate cleaning liquid addition port;

    • Hole using heating technology, the sample is heated evenly, not with the overall heating mode;

    • Heating control program: using PID temperature control techniques, the actual design of the heating temperature and the heating temperature error of less than ± 1 ℃;

    • The heating temperature may be set hole and the countdown time digestion, digestion can automatically stop end;

    • During digestion, by the front display real-time monitoring of each hole digestion actual countdown time heating temperature and reflux;

    • Digestion bottle design: digestion flask volume of approximately 300ml, digestion can be directly on the end of the titration bottle, without pipetting;

    • 7-inch LCD touch screen design, the touch screen design over the design splash protective cover;

    • Operation mode: the parameter can be set up a key to start automatically complete digestion procedure (digestion holes each digestion temperature reaches the set automatically, automatic return countdown, the automatic stop), without human duty.
