DOS-218 portable dissolved oxygen meterDetailed product description：

The DOS-218 portable dissolved oxygen analyzer has a low power consumption microcontroller for measurement and control, with low power consumption and high reliability. It can achieve intelligent measurement and uses polarographic method for measurement. It has the advantages of stability, reliability, simple and convenient operation (can be operated with one hand), etc; This instrument can indicate the measurement results in two units of dissolved oxygen content, namely oxygen concentration (mg/L or ppm) and oxygen saturation percentage (%). In addition, it also measures and displays the temperature of the measured medium.

Features:
1. Diverse functions, using imported components from TI company, adopting low-power design, with power management functions such as undervoltage display and automatic shutdown
2. This instrument can measure the concentration, saturation, electrode current, and temperature of dissolved oxygen analyzer
3. Adopting microprocessor technology and wide screen LCD display. Simultaneously equipped with operation prompt function, easy and convenient to use
4. It has automatic temperature compensation function.
5. It has functions such as power-off protection
6. Instrument rating IP65, waterproof and dustproof, suitable for field operations
