T5 Tensiometer

The T5 Tensiometer is specially made for punctual measurements, for example in soil columns, small lysimeters or pots.

With an active surface of only 0,5 cm2 and a diameter of 5 mm the ceramic tip has all advantages of small dimensions: little soil disturbance, punctual pick-up and fast response.
The special version T5x can achieve a measuring range of 200 kPa.

The T5 can be installed in any position and orientation. Bubbles are easily detectable through the transparent shaft. Output signals are balanced.

Typical Applications

• Punctual measurement of water
  potential
• Miniature lysimeter studies,
  together with micro samplers and
  soil temperature probes
• Determination of pF/wc and
  K/Psi in soil columns, soil cores or
  soil sampling rings
• Determination of leachate and
  capillary water movements
• Controlling irrigation
• Pot experiments
• Measurements in the upper soil horizons in the field
• Monitoring with data loggers
• Spot readings with the INFIELD7

Advantages

• Accurate zero-tension reading
• Fast response: With sufficient fillingthe T5 responds within 5 seconds to an applied air pressure change of 0 to 85 kPa
• Most standard T5 reach a range of at least 150 kPa when delivered.

Limitations

• Not for dry soils
• Not frost resistant
• In the field applications require impact protection
