YSI Professional Instruments

For those who demand the very best water quality data

YSI products, which are available from Geotech Environmental Equipment, are ideal water monitoring solutions. Whether you are concerned with climate change, floods, droughts, stormwater runoff, clean drinking water, or healthy ecosystems, YSI products are reliable data collecting instruments. YSI instruments, software and data collection platforms are focused on environmental monitoring and testing. The integrated systems will obtain critical data about the quality of water.

YSI Professional Series Handhelds

YSI Professional Series Handhelds:
Pro Series instruments are designed to be extremely versatile, tough and smart in the field. They accommodate a wide assortment of cables, sensors and accessories. Want to measure DO in the field? Want that DO to be polarographic, galvanic, or optical technology? Maybe you're interested in pH, DO and nitrate together? Or perhaps you need an instrument you can use in the field and also measure BODs in the laboratory? Whatever you need... the Professional Series line has the solution.

The Pro Series family consists of the Professional Plus, ProODO, Pro1020, Pro1030, Pro2030, Pro20 and Pro30. For easy decision-making, please refer to the matrix on page 3 of the spec sheet.

It's Spring!
Time to wake up
your equipment!

Tips on how to have your equipment ready and fit for Spring

Ok, it is a bit early to talk spring, but not for sampling and monitoring ground and surface water.

What we are referring to is your equipment. The electronic gizmos sitting on your shelf collecting dust over the winter months. This is when we get most of the panicked calls about equipment not calibrating, turning on, or generally just being temperamental.

So, now is the time to think about this equipment, not next month, not the month after, now!

Here is a list of pointers to help you find out if you have any issues now, so you can have them resolved prior to loading the truck or flying out. Checking things out now will keep you from losing time and money in panicked overnight shipments for parts, calibrations, repairs, and possibly rental equipment to get you going when your stuff fails.

1. Turn It On:
Does it turn on? Does it need new batteries? Alkaline batteries left in equipment can off-gas over time, causing corrosion. Check them now.
If rechargeable, time to give it a good charge and test it out. Better to know now if that battery can hold a charge or if the charger is defunct.

2. O-Rings:
Yep, O-Rings! Any meter with submersible field changeable sensors are bound to have O-Rings to keep the water out of the connections. Take out the sensors, replace or re-silicone the O-rings (remember a little bit of silicone, just enough to make the O-ring sticky, not slippery). A word of warning; do not get silicone into the pins or actual contacts. You will do more harm than good!!

3. Sensor Check:
Water quality sensors such as pH and Dissolved Oxygen should be stored wet.

Never store in DI water! Never. Water is the “universal solvent”; DI water will kill sensors dead if they are left in it for a period of time. Clean with it, do not store with it!


Spring Wakeup

pH storage solutions are available. In general, storing in pH 4 buffer is a safe bet, please check your manual!

Dissolved Oxygen (DO) sensors can typically be stored with a sponge or with just a small layer of water in the storage chamber that does not directly contact the sensor. A small piece of sponge holds water longer.

4. Calibrate it Now:
Sure, you will have to calibrate again before you use it, but find out now if any sensors are out of whack, and if there are any that need repair or replacement, now is the time. Ground shipping is still far cheaper than Next Day Air.

5. Other Stuff to Check:
a. Cables and connections. Any bent pins? Corrosion?
b. Communication cables. Still got them if you need them? Test them out.
c. Software. Any IT updates in your office knock your software out? Test.
d. Firmware updates. These fix bugs with equipment so they can function better.

This is just a basic list, and air quality instruments not used for a season will need the same love and attention as water quality instruments. If you use sampling pumps, time to break them out and give them a test, too. Remember, this equipment gets you your data, which is what you are out there for…right!?

If you run into issues, call us now

let’s figure out what happened together!
