1、 Purpose:：
Soil water potential is a commonly used instrument and equipment, mainly used for precise measurement of water potential in soil, widely used in industries, agriculture, scientific research, environmental protection and other fields.
1. Water potential sensor:
1.1 Power supply voltage: 5-24V power supply
1.2 Signal output: voltage/current output
1.3 Water potential measurement range: ± (10%+2 kPa) from -9 to -100 kPa
1.4 Cable length: The sensor comes standard with a 2-meter cable. We can provide customized cable lengths. The maximum cable length is 50 meters. If you need a longer cable length, please contact us
1.5 Host usage: The instrument comes standard with a sensor probe that can be interchanged. After manually scanning the sensor, it can be used directly without affecting the accuracy of the sensor;
1.6 After an unexpected power outage, the host automatically saves data to the TF card;
1.6 Minimum resolution: 0.1 kPa
1.8 Balance time: less than 20 seconds.
1.9 Working conditions: The ambient temperature is -40~60 ℃, and the relative humidity is less than 90%
2. Recorder display host:
2.1 Recording capacity: 5 million sets of data
2.2 Startup Method: Manual Startup
2.3 Storage Method: Scheduled Storage/Manual Storage
2.4 Recording interval: The shortest recording interval is 1 minute, and the sampling recording interval can be set arbitrarily in minutes, hours, or days.
2.6 Power supply mode: built-in high-capacity 7.4V lithium battery; An external power supply (8.4V power supply) can also be used for power supply
2.7 Communication: USB Data Cable
2.8 Sensor type: Thermistor
2.9 LCD display: 40mm × 62mm
2.10 Working environment: -20 ℃~70 ℃ (whole machine)
main features
1.1 Integrated design, LCD screen display, can manually or freely set interval time to collect and store information, and 1.2 No need to connect to the computer. Pull out the card from the host and use a card reader to directly read data from the computer;
1.3 High measurement accuracy and corresponding fast speed
1.4 The soil has a relatively small impact and is widely used in various regions
1.5 Low price, suitable for China's national conditions
