This edition reviews the series of Enviropro soil moisture, temperature and salinity sensors—a must-have series of precision sub-surface soil probes for any farmer or researcher demanding reliable and repeatable measurements.
About the Makers of Enviropro Sensors, Entelechy
Entelechy is the proudly South Australian company behind the Enviropro series of sensors. The company’s mission is to create technology for the world’s primary producers faced with the challenge of feeding a rapidly growing population while minimising resources and environmental impacts.
Entelechy strives for quality and the highest level of accuracy in its precision agricultural products.
Introducing Enviropro Soil Probe Sensors
The Enviropro series offers eight straightforward, robust, and practical multi-function, multi-level sub-surface instruments for taking continuous, reliable, and repeatable soil moisture, temperature, and salinity (EC) measurements.
Four Key Benefits of Enviropro Soil Probe Sensors
- Saving Water: With the ability to test soil moisture levels at the root level, Enviropro capacitance probes will inform when to irrigate and how much water your crops need.
- Identifying Trends: Enviropro sensors can measure and log significant amounts of data over long periods so you can make informed decisions based on historical events and trends.
- Saving Time (and Money): Manually sampling soil is time-consuming, and sending samples away for laboratory analysis is costly. An Enviropro soil probe system gives you quick and easy access to soil information at any time while reducing the need to venture into yards and paddocks to conduct tests.
- Improving Yields: Enviropro sensors provide precious data about the condition of subsoils down to the root zone. Highly accurate information of this type enables agricultural professionals to optimise inputs like fertilisers, energy, and irrigation.
Unique Features of Enviropro Soil Probe Sensors
- Sample large amounts of soil: Enviropro sensors' measuring influence field is significantly greater than similar capacitance soil sensors. This advantage results in more meaningful soil measurements.
- Compensated measurements for accuracy: All Enviropro sensor models compensate salinity and moisture measurements for temperature variations. Further, the sensors compensate moisture measurements for salinity variations.
- Interface Options: The Enviropro series of sensors interface to all SDI-12 compliant digital loggers. An example includes; YDOC RTU 4G SDI-12 & Analogue. For help finding the best logger for a specific application – contact us!
- Impressive range of sensor lengths: Find a suitable sensor for any crop type - choose from 40, 80, 120 and 160cm sensor length options.
- Futureproof: Envirpro sensors are wholly encapsulated to ensure longevity and maximum protection against environmental degradation.
- Maintenance-free: Enviropro sensors leave the factory individually calibrated and will never require recalibration in the field. This feature means lifetime sensor-to-sensor and probe-to-probe repeatability!
- 100% designed and manufactured in Australia: With over 20 years of proven excellence in the field.
Enviropro Model Overview
Standard and Pro sensors are available in varying lengths, sensor numbers and measure different parameters as follows:
- Standard (EP100GL): Moisture and temperature.
- Pro (EP100G): Moisture, temperature and Salinity (EC).
