List of Meteorological Instruments

1. AUTOMATIC WEATHER STATION

An LCD screen displays current and high/low readings. Add up to 5 plug-in sensors and customize your station to your measurement needs. A 12-month battery power source (4 AA batteries) means no solar panels to purchase or maintain. Preassembled sensor array with mounting hardware makes setup quick and easy. Add-on sensors plug directly into the station - no complex wiring or calibration required. U.S. or metric units of measure. Mounts to post, tripod, or 1 1/4 pole. The Weather Station helps you optimize your irrigation and IPM programs. The comprehensive water management system enables you to assign discrete K-factors to each crop/field you track for evapotranspiration and irrigation amounts.
Applications :
• Evapotranspiration • Solar radiation • Air temperature • Relative humidity • Rainfall
• Wind speed and direction • Wind chill • Dew point

2. AUTOMATIC DIGITAL RAIN GAUGE

Rain gauge with event logger is designed to record detailed rainfall history including quantity, time, date, duration and intensity. The event logger is user programmable to match the bucket’s tip size and features a minimum recording interval of 0.5 seconds. With a 0.25 / 0.20 mm bucket, 8,000-events capacity will store up to 1.6 meters of rainfall data. The data is stored in the units nonvolatile EEPROM memory, which retains collected data even if the battery fails. The unit can be launched and data read easily in tabular form or exported to spreadsheets such as excel for windows, Power: user replaceable, 3V lithium battery with an expected life of one year of continuous use. Comes with COM 232 and USB port options.

3. ORDINARY OR NON-RECORDING RAIN GAUGE

Non Recording Rain Gauge is manufactured from non-corrosive fiberglass reinforced plastic as per IS: 5225: 1969 and is meant for collection of the total quantity of rainfall over a specified period of time. It consists of collector assembled with Gunmetal Ring, Funnel, Locking Rings and Base. Rain Gauges are available in two different capacities 100 sq. cm collected area and 200 sq. cm collected area. The collector of the rain gauge is exposed above ground level while the receiver is fixed partially below ground level.
Applications :
• Measures rain and snow. • High accuracy. • Rugged and Reliable. • Corrosion resistant construction.
• Meets National Weather Services specification No. 450.2301 Of USA..

4. ANEMOMETER CUP COUNTER.

Anemometer Cup Counter is used primarily for measuring the run of the wind over a period of hours or a whole day rather than over the shorter period required for observation purposes. This instrument is manufactured as per IS: 5912: 1970 and have three aluminum cups attached to a central spindle which is connected by worm gearing to a mechanical revolution counter. The gear ratio is so selected that the counter indicates directly the total run of wind passing at the point of observation up to the range 0 to 9999.9 km.
Digital hand-held anemometers are also available.

5. SUN – SHINE RECORDER.

This Sun – Shine Recorder is manufactured as per IS: 7243: 1974, and is used for accurate measurement of the duration of Bright Sunshine. Basic main components are Bowls that are precisely manufactured from Bronze as per IS : 306 : 1968. The Base is of White Marble. The Sphere Bowl is made from uniformed and well-annealed air bubbles free Glass having good surface finish. This instrument is supplied with recording graphs for one year, and standard stenciled curve for comparison.

6. OPEN EVAPORATION PAN.

This Sun – Shine Recorder is manufactured as per IS: 7243: 1974, and is used for accurate measurement of the duration of Bright Sunshine. Basic main components are Bowls that are precisely manufactured from Bronze as per IS : 306 : 1968. The Base is of White Marble. The Sphere Bowl is made from uniformed and well-annealed air bubbles free Glass having good surface finish. This instrument is supplied with recording graphs for one year, and standard stenciled curve for comparison.

7. DIGITAL TEMPERATURE-RH LOGGER.

Battery operated digital temperature & RH logger records the values at users selectable time interval in its non-volatile EEPROM which retains data even if battery fails. Data can be easily downloaded to PC for further analysis.Simultaneously measures and displays three parameters. ±1% full scale accuracy at 3-decimal resolution across a wide measurement range. Ion-measurement capabilities with 3-digit resolution . Accepts two-cell and four-cell conductivity probe to measure up to 500 m/s — meter measures pure water . Selectable multi-point calibration for more accurate conductivity measurements or single-point calibration for quick, convenient calibration with no mistakes.

8. QUANTUM LIGHT METER.

he light that drives photosynthesis in plants is Photosynthetically Active Radiation, or PAR light. This is also referred to as Quantum light, because it is measured in units of moles striking an area over time. Though PAR light ranges from 400 to 700nm, the region brightest to human eyes is the area of least effect on plants. Measuring quantum light can tell you if your plants are getting a sufficient amount of usable light.
Features :
•Accurately measures radiation for plant growth. •Can be used with 3 sensor bar for averaged PAR reading.
•PAR (Photo synthetically Active Radiation) refers to the quantity of light reaching a given plant through out the day.
•Measures photosynthetically active radiation (PAR) from 400 to 700 nm.
•Range of 0 to 2,000 µmol·m-2·s-1 •Available in a variety of configurations for your convenience.

9. FIELD SCOUT® EXTERNAL LIGHT SENSOR METER.

This light meter can read any of Spectrum’s light sensors, which come with 6ft/2m cables. Just plug in a sensor, choose it on the LCD display, and start measuring UV, Quantum Light, or Solar Radiation. Sensors can also be used with Weather Stations and Data Loggers. 9 volt battery included.

10. Self-Recording Digital Rain Gauge.

Automatic Digital Rain Gauge is a low-cost, rugged, and compact instrument designed to provide a cost-effective, low power solution for the proper real time event recording of rainfall. The instrument uses a tipping bucket mechanism to produce a contact closure every time it receives a predetermined small quantity of rainfall (0.2/0.25 mm). An accurate 8” diameter collector meets NWS specifications for statistical accuracy and gives an aperture of 330 cm2. The sophisticated Logger within this Tipping Bucket Rain Gauge records every rain event with date and time stamp. Memory is sufficient to store several year data at 1 minute interval.

11. Temperature-RH Data Logger.

This Temp-RH Data logger records up to 16,000 humidity readings and 16,000 temperature readings. You can choose from two start methods, instant or manual. Data loggers feature dew point indication, selectable data sampling rates, user-programmable alarm thresholds, and status indication by LED. Each data logger comes complete with a 3.6V Lithium battery, protective USB cap, mounting bracket, and Window®-compatible software for analysis.

12. Wind Data Logger

The WindLog™ is a compact, inexpensive wind data logger, designed to record Wind Speed and Wind Direction. The wind logger contains enough memory to store one year data and operates on three AA batteries. Battery life is around 6 months. The Mini-Aervane wind sensor is equipped with low friction race bearings. This reduces the threshold to approximately 1 mile per hour. The wind direction sensor has a 16-point resolution. Logged direction readings are averaged readings. Each WindLog ships with a free Windows based application, WindSoft. WindSoft, can generate statistics, graphs and reports.
