This system offers convenient and flexible tools for measuring and analyzing incident and transmitted Photo synthetically Active Radiation (PAR) in Crop and Forest canopies. It provides vital information about the penetration of PAR into crops and forest , and is essential in work such as comparative crop studies, for separating out the effects of cultivars and treatment. It is particularly well suited to low regular canopies (as found in many agricultural crops). It can be used in most light conditions. The sensor probe has an array of 20 PAR sensors embedded in a 1m long probe, and is connected handheld Data logger. One PAR Sensor is also connected with data logger for reference incoming radiation. When a reading is taken, all sensors are scanned and the measurements transmitted to the data logger. The average light level along the probe is calculated. further you can download data from data logger to a computer (USB Port) with the help of "Virtualware" (PC Interface Software).

This standard instrument offers professional soil and rain monitoring and outstanding value for money. Our instruments are known for their precision measurements, rugged construction, wide operating temperature range and low power consumption. This instruments consists of a weatherproof enclosure which contains the data logger and power supply, and comes complete with a solar panel, tripod stand and Soil Temperature, Soil Moisture & Rainfall sensors. The system is powered by rechargeable sealed maintenance free batteries with integral 12V/10W solar panel, which will easily keep the batteries charged throughout the year. The type of ground, vegetation, buildings and other obstructions that can affect measurements, and so you need to assess the site carefully. All sensors are powered directly from the data logger and need no external signal conditioning.

This system allows monitoring of erosion and deposition automatically. Conventional, manual methods like erosion pins and resurvey techniques can only reveal net change to a site since the previous field visit. They cannot therefore reveal the ‘true’ temporal distribution of erosion and depositional activity. The high-resolution information from this system, however, is incredibly valuable in process and management studies for erosion. This system consists of a weatherproof enclosure, which contains the data logger and power supply, and comes complete with a solar panel, tripod stand and sensor.

The automatic soil moisture suction & Soil Temperature Recorder is a complete system for monitoring, logging and graphing 7  point Soil moisture & 1 point Soil Temperature readings.  Automatically reads the sensors, 12v battery powered monitor, Battery Charging Through solar panels, Reading frequency from every minute to every day and  adjustable to suit you, 8 sensor capacity, includes temperature probe, In-field display of current reading, Download the history to a Computer through pockable data shuttle, Monitor current values. Data is saved in Excel format and can be exported.

The double ring Infilltrometer is a simple instrument which is used to determine the infiltration rate of water into the soil. The infiltration rate is determinate as the amount of water per surface area and time unit, which penetrates the soils. This rate can be calculated on the basis of the measurements and the DARCY's law. Several measurements can be executed simultaneously, yielding a very reliable and accurate mean result. As vertically infiltrated water runs away to the side. The outer ring of the Infiltrometer serves as a separation. The measurement exclusively takes place in the inner ring through which the water runs virtually vertically. The instrument consists of two rings, driving plate, for inner and outer rings. The two rings are driven into the ground and partially filled with water. The double ring design helps prevent divergent flow in layered soils. The outer ring acts as a barrier to encourage only vertical flow from the inner ring. 

The standard set of the double ring Infiltrometer consist of 2 steel rings with different diameters, a hammer, floats, a stainless steel hammering cross and a stopwatch.
