What is it?
The TH2O is a new way to measure volumetric soil moisture content. It combines ease of use and accuracy with low cost, to give growers, land managers and engineers
immediate precise soil moisture data.The probe is reliable even in saline soils and its compact size means minimal substrate disturbance.
How does it work?
The sensor sends a microwave signal and analyzes a reflected signal to measure the dieletric constant (theta) of the soil. The dielectric reading is then converted to
volumetric water content (±2% accuracy). The battery-powered hand held readout provides instantaneous readings for mineral or organic soils.
How do you use it?
The TH2O probe is inserted into the soil and when the readout button is pushed the LCD shows the soil water content as a decimal value.
You may also install access tubes and take soil moisture reading from deep within the soil profile.
Customer Feedback
"We have had the TH2O for about three years, and bought another one this year. We are using the TH2O to watch putting surfaces,
especially during summer, to track dry spots and irrigate to avoid drought stress."
- Todd Towery, Pinnacle Country Club
“It has worked very well for us, especially in predicting localized dry spots. It is one of the best tools that we have purchased
in a long time. The TH2O takes the guess work out of irrigating.”
- Donald Altman, Forest Hills Country Club
“We have four TH2O 's, one for each of our reps. They are working well to demonstrate the effectiveness of turf surfactants to
golf courses, and the customers that bought them, love them."
– Gary Rehm, Metro Turf Specialists
“We are able to maintain our turf much more scientifically through the use of this meter. We have a good grip on where the wilt
point is, and how long it takes us to get there, for any given day. So, this allows us to very accurately maintain our greens.”
- Bill Stein, Minocqua Country Club
“This meter would make a great tool to anyone who is conscientious about the health and playability of their greens and golf course."
– Bill Stein, Minocqua Country Club
