DO 100 / DO 1200

The Dissolved Oxygen (DO) Sensor provides accurate, long-term measurements utilizing patented diffusion cell technology. Designed for long-term deployment with no moving part, the DO sensor provides an effective means of obtaining continuous measurements with minimal maintenance requirements.

Sensor Output:

• DO 100: 4-20mA
• DO 300: RS 232 (also includes internal logging)
• DO 1200: SDI-12 serial

Sensor Features:

• 0-20 ppm DO range
• 0-55 degrees Celsius range
• +/- 1% DO linearity
• +/- 0.3 ppm DO accuracy
• 10 - 14V supply voltage
• 1 second warm-up time to first reading
• Response time of 40 minutes
