Industrial
PMC VL Series Pressure Transducer (Water Depth)
The PMC Engineering VL series pressure transducers are an industrial grade sensor made in the US, suitable for deep bores or applications where long-term stability, high precision and long-lasting contruction materials are required. We get these made to order depending on the range and accuracy required, available in straight or right-angle configuration.
D-Opto Dissolved Oxygen (DO)
The D-Opto Dissolved Oxygen (DO) sensor is based on a field proven optical technology that has been successfully used for many years. The sensor enables long term accurate monitoring of dissolved oxygen levels in streams, rivers, lakes and marine environments with minimal on-site maintenance and servicing. We also use the D-Opto Shutter to protect the sensing window from sediment build up and damage between readings in harsh environments.
Met One E-BAM
The E-BAM (by Met One Instruments) is a portable, real-time air quality particulate monitor, comparable to U.S. EPA methods for PM2.5 and PM10 particulate measurements. Harvest provide a customised solution to integrate with these instruments.
Acclima TDR-315H True TDR Soil Moisture Sensor
The Acclima TDR-315H is a true Time Domain Reflectometry (reflected radar pulse) soil moisture sensor system wrapped up in a small, rugged, permanently installed package. It is a major, patented breakthrough in soil water measurement technology. This probe is protected by international patents so any other probe that claims to be True TDR is either infringing this patent or most likely not a true TDR probe.
An added bonus is that this soil moisture probe also measures soil temperature which is useful to know when to expect plant growth.
Its three-pronged design means that installation consists of pushing the probe in to the "cliff face" of a newly dug hole so the probe goes into undisturbed soil and the readings are accurate as soon as the probe has been installed. Most other probes take weeks or months before the disturbed soil has similar compaction to undisturbed soil. The TDR technology provides the most accurate results of any electronic moisture probe. It is far superior to older style capacitive probes which give inaccurate readings when soil conductivity changes (eg after adding fertiliser). Unlike capacitive probes, True TDR probes do not need external calibration.

Gill Windsonic Ultrasonic Wind
The Gill Windsonic Ultrasonic Wind Sensor is a high-end meteorological grade wind speed and direction sensor made in Europe. It has no moving parts, doesn't require calibration, and the physical design of the sensor means the top protects it from damage (i.e. birds). This sensor is a great fit for applications where met-grade performance is required.
