Specifications
Ordering Information

This newest Dissolved Oxygen analyzer is available in a single sensor input version, in an enclosure that takes up half the space of most other transmitters.The single input Model 30 has two 0/4–20 mA outputs that can be programmed to correspond to the measurement and temperature. Zero and 100% saturation are simple to calibrate prior to installation of the sensor. In addition, it is easy to adjust the on-line display by a quick one-point In Process calibration of the % saturation. This is useful when the correct value is known through a separate off-line analysis.

The Model 30 features an easy-to-use, intuitive menu that makes advanced programming and calibration simple. On-screen full text and phrase prompting does away with cryptic mnemonic based instrument displays.
