The Van Veen grab is used for sampling disturbed sediment. This device is used with a rope/cable and is manually controlled. The Van Veen grab is available in four different capacities. Fast indication of sediment type  Four sizes of Van Veen grabs available for every need Inert stainless steel construction  Easy operation    Easily collect samples at the bottom of lakes, rivers with the Van Veen grab. Simply open the jaws and take a ‘grab’ when reaching the bottom. When hoisting the rope up again the jaws will shut tight and the sample is taken. The Van Veen gab will give you a fast indication of the sediment type and is available in four different sizes. The stainless steel construction ensures that the Van Veen grab is strong and of high quality. The mode of operation of all Van Veen grabs is the same. At the surface the jaws are pushed open and kept in that position by a hook. To keep the hook in the right position the Van Veen grab should be sunk at a steady, not too high, pace. Both jaws are fitted with holes to allow air to escape during the sinking. If these holes were not there, the air would escape when taking the sample, which would result in interference with the sample. As soon as the jaws touch the bottom, the hook loosens its grip, so that, when hoisting the rope again the jaws will shut tight because of the leverage by the rods.   It is recommended to take at least 6 samples from every location and to base your conclusion on the total of the samples. This is especially important when the bottom is less regularly shaped and the bottom material consists of a mixture of materials.

A Rain gauge is a device to measure liquid rainfall amount and intensity. The device is composed of a rain collector cone and a double-chamber tipping bucket connected to a magnet. The magnet operates one reed switch, which generates im-pulses that can be counted by external meters. Siphon versions (DQA230.1-231.1-230.3) are equipped with a siphon placed on the cone’s nozzle; it has function during heavy rain, to regulate the flow into the bascule permitting all the water to fall inside the tipping bucket. This solution gives its best results where the main need is the measurement of the total amount of rain over long periods.Class A rain gauges versions (DQA230-231-235-236) have the “Class A” class accuracy as described by the UNI EN 17277:2020 standard. It is the most accurate class for intensity measurement. For the Class A accuracy achievement, a cor-rection formula on the data acquisition system is required.

Sunshine recorders automatically registering time and duration of insulation are used at meteorological and climatologically research centers, observatories, spas and health resorts, in agriculture, horticulture, viticulture and vegetable gardening. The instruments are set up on flat roofs or on clear ground in such manner as to be well exposed to solar radiation, during the whole day. The type of instrument to be chosen depends on the latitude of the place installation. This recorder consists essentially of a glass sphere mounted concentrically in a section of a spherical metal bowl, the diameter of which is such that the sun stays are focused sharply on a card held in the grooves, in the bowl. Three overlapping pairs of grooves are provided in the bowl to taken up cards suitable for the different seasons of the year. A sunshine recorder is a device that records the amount of sunshine at a given location or region at any time. The results provide information about the weather and climate as well as the temperature of a geographical area. This information is useful in meteorology, science, agriculture, tourism, and other fields. It has also been called a heliograph. There are two basic types of sunshine recorders. One type uses the Sun itself as a time-scale for the sunshine readings. The other type uses some form of clock for the time scale.   Older recorders required a human observer to interpret the results; recorded results might differ among observers. Modern sunshine recorders use electronics and computers for precise data that do not depend on a human interpreter. Newer recorders can also measure the global and diffuse radiation.

This is an easy to use digital soil moisture sensor. Just insert the sensor in the soil and it can can measure moisture or water level content in it. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil.The sensor includes a potentiometer to set the desired moisture threshold. When the sensor measures more moisture than the set threshold, the digital output goes high and an LED indicates the output. When the moisture in the soil is less thatn the set threshold, the output remains low. The digital output can be connected to a micro controller to sense the moisture level. The sensor also outputs an analog output which can be connected to the ADC of a micro controller to get the exact moisture level in the soild.

Self-recording rain gauge (SRRG) is an automatic device used to record a continuous rainfall for 24 hrs on a daily chart, if rain occurs.The characteristics of rainfall events viz. onset and cessation of rainfall, duration of rainfall, intensity of rainfall and the total amount of rainfall in mm can be obtained from the rainfall chart.DETAILS OF EQUIPMENT It is a float type rain recorder in which the rain is led into a float chamber containing a light, hollow float. The rain gauge is installed on a level ground and fixed on a masonry foundation of 60 × 60 × 60 cm3 sunk into ground. Base of the gauge is cemented into the foundation so that the rim of the gauge is exactly 75 cm above the case of self-recording rain gauge. If the height of the rim were more, the rainwater collected would decrease because of the change in wind speed near the ground. Rainwater is entering the receiver through an 8-inch diameter funnel. The receiver is consisting of float and siphon chamber. MEASURING PROCEDURE A pen is mounted on the stem of the float and as the level of water rises in the receiver, the float rises and the pen records on a chart placed on a rotating drum with clockwork arrangement, the amount of water in a receiver continuously. The clock work drum revolves once in 24 hrs. Siphoning starts automatically when the pen reaches the maximum point of the chart. If the rain continues, the pen rises again from the zero line on the chart. If there is no rain, the pen traces the horizontal line from where the rain stopped

The evaporation pan of this standard set is made of stainless steel and has the dimensions of a “class A“ evaporation pan, namely 54 mm (10 inches) in height and 1206 mm (47.5 inches) in diameter. The evaporation pan is installed on the wooden support, which is set and levelled on the ground in a grassy location, away from bushes, trees and other obstacles which obstruct a natural air flow around the pan, thus representing open water in an open area.Daily the result of evaporation and precipitation is measured within the still well, by means of a high quality evaporation micrometer with a measuring range of 100 mm and an accuracy of 0.02 mm. This accuracy can be obtained because the still well prevents rippling of the water surface.The amount of evaporation is a function of temperature, humidity, wind and other ambient conditions. In order to relate the evaporation to wind current or expected conditions, the maximum and minimum temperature as well as the amount of air passed are recorded with the evaporation. For a more exact use of the evapora- tion pan it is recommended to use an additional wind path meter.
