Introduction Dear Customers, Thank you very much for choose the high-quality BQ401 handheld multi-parameter probe and meter from Shanghai BOQU Instrument CO., Ltd. Before you use it, please read this manual in detail, it will be help you for using and maintenance of this instrument, and can avoid unnecessary troubles due to improper operation and maintenance. -
Page 5: 1Summary
BQ401 are independently developed by BOQU Instrument. This combination can measure temperature, optical dissolved oxygen, fiber optic turbidity, four-electrode conductivity, pH, salinity, etc. The BQ401 multi-parameter handheld probe can support up to 4 types of probe measurements. When connected to instrument, these data can be automatically identified. This meter is equipped with a back light display and operation keyboard. -
