How to Change the Electrode on the IC-ST20S Starterpen Salinity Meter by OHAUS
An electrode is generally a consumable item. Depending on your usage, Instrument Choice recommends replacing your device’s salinity, conductivity, or pH electrode every 6-24 months to ensure reliable results.
Three main things will alert you that it’s time to replace an electrode:
- Difficulty or inability to calibrate the device
- Unstable, variable or slow readings; or
- Physical signs of damage or wear and tear.
The IC-ST20S is a value-for-money salinity meter that our scientists often recommend. This salinity meter offers a simple-to-use, fast, straightforward, and no-frills operation. What’s more, the manufacturer OHAUS is renowned for the quality of its devices and the IC-ST20S doesn’t disappoint.The device boasts a sturdy construction and has proven to be durable even in the toughest of environments. We also love that the design incorporates a replaceable electrode. Rather than replace the entire device, you can change the electrode and be back using your salinity meter in a matter of minutes.
When the time comes, follow this step-by-step guide to changing the IC-ST20S salinity meter electrode.

How to Replace the Electrode Probe on the IC-ST20S Salinity Meter by OHAUS
- (0:26) Pull to remove the storage cap.
- (0:28) Twist off the red probe ring around the electrode.
- (0:35) Gently pull to unplug the old probe and separate from the meter.
- (0:42) Plugin the new electrode, paying attention to the position. The tracks on the new electrode will line up with the electrode body.
- (0:53) Screw the probe ring back in place, tighten and replace the probe cap.
CONCLUSION
It’s essential to replace an electrode on a meter when the sensor is noticeably damaged, will not calibrate or, that is giving unstable and slow readings. With the IC-ST20S, this is a quick and straightforward task that is much cheaper than replacing the entire device.

Maintaining accurate records of temperature measurements is vital for a wide range of industries. The EL-USB-1 Temperature Data Logger is a go-to, and versatile option for temperature data logging that can track up to 16,382 different temperature measurements, as well as record and store temperature readings between -35 and +80 C.
The device is perfect for measuring and tracking temperature in fridges and freezers, for transporting temperature-sensitive goods, preserving pharmaceuticals and vaccines, recording ambient temperatures and for many more applications.
A common question Instrument Choice scientists receive is, “How do I change the battery in this temperature data logger.” If this concerns you too, check out this short video – it has all your answers!
Most weather stations use batteries for primary or backup power. The Davis Vantage Vue is no exception. Replace the batteries in your Davis Vantage Vue indoor console and outdoor sensor suite every 6-24 months, depending on how much you use your device. This will ensure your weather station operates efficiently with the minimum disruption to data collection.
Generally, your weather station will alert you if your station’s battery is running low. However, if at any time you start to notice strange or inconsistent readings, an excellent first troubleshooting step is to replace the batteries.
