The EasyCal is a small device that makes DO probe calibration easy, fast and accurate. The version for use with mg/l systems consists of a probe holder and a box with air pump and display, whilst the version for % saturation has no display.
To calibrate you simply take the probe up, wipe the membrane clean, place it in the holder and return it to the water. Switch the EasyCal on and after a few seconds air-saturated conditions are established at the probe. You then either calibrate to the mg/l value shown on the display, or to 100% saturation as appropriate.
