Ohaus ST400D Portable Dissolved Oxygen Meter

The ST400D is a practical, affordable, and low maintenance DO portable meter.  It is equipped with optical technology which is ideal for applications that require simple yet accurate DO measurements.

The optical probe requires minimal maintenance.  Frequent membrane replacement, and warming up and stirring of samples when taking measurements, are not required.

The meter is equipped with a colour LCD display and is designed to fit comfortably in the palm of your hands. The automatic/manual endpoints enable easy recall of last calibration data and stored information with one touch.  The simple calibration process offers quick delivery of measurements and automatic temperature and barometric pressure compensation ensure accurate results.
