Soil Probes

EnviroPro Soil Probes from Instrotech
EnviroPro® precision sub surface soil probes 
have been made and used continuously in all types of soils and applications since 2002. Physically robust with reliable and repeatable readings, EnviroPro® soil probes are backed up by a no-nonsense 5-year replacement warranty.  EnviroPro® soil probes feature essential Temperature and Salinity compensation in their soil Moisture readings.

Applications for EnviroPro® soil probes range from single probe applications coupled to a local data logger for soil moisture to highly sophisticated multiple installations.  Readings may be logged and data transmitted via wireless or GPRS cellular modems to base-stations or web-servers.  Being sub-surface types, EnviroPro® soil probes can be well protected from physical damage.  They are equally at home buried in irrigated or dry-land farming installations.

With connectivity to many types of third-party loggers and transmitters, EnviroPro® soil probes lend themselves to easy integration in information-rich soil monitoring systems.  SDI-12 version 1.3 compliant EnviroPro® soil probes may now be upgraded in place via telemetry and loggers which support Transparent Mode.

Instrotech have supplied and supported EnviroPro® soil probes as national and international distributors since 2011.
