The TP-PW-II Plant Water Potential Analyzer is a dedicated instrument for measuring the water potential of plant tissue. Water potential is the key physiological parameter that governs how water moves through a plant's vascular system, and quantifying it helps researchers understand plant water status, drought stress responses, and overall hydraulic health.
Beyond measuring water regime, the instrument enables extraction of plant conduit juice (xylem sap) for compositional and component analysis—making it a dual-purpose tool for both water-relations research and plant sap chemistry studies.
The analyzer covers a measurement range of 0–3.5 MPa with a read accuracy of 0.01 MPa, giving researchers the resolution needed to detect meaningful differences in water potential across experimental treatments, growth stages, or environmental conditions. Results are displayed on a clear LCD readout for straightforward in-lab use.
Typical applications include crop physiology research, irrigation science, plant stress biology, and agronomic field trials where understanding plant water status is central to the study design. It is easy to operate, measures quickly, and works for both indoor and outdoor tests.

What measurement range does the TP-PW-II cover?
The analyzer measures plant water potential from 0 to 3.5 MPa, which spans the range relevant to most crop and research plant species under normal to moderately stressed conditions.
How precise are the readings?
The instrument has a read accuracy of 0.01 MPa, providing sufficient resolution to detect statistically meaningful differences in water potential between experimental treatments or time points.
Can the instrument be used for plant sap analysis as well as water potential measurement?
Yes. In addition to measuring the plant water regime, the TP-PW-II is designed to extract conduit juice (xylem sap) from plant tissue, allowing researchers to perform compositional and component analysis on the collected sample.
What does the system include, and how large is it?
The system is supplied as a dual-unit configuration. The two units together have approximate dimensions of 630 × 400 × 310 mm and 560 × 400 × 280 mm respectively.
What kind of display does the analyzer use?
The TP-PW-II uses an LCD display to present measurement readings, allowing clear, direct viewing of water potential values during operation.
