Automatic Weather Station
2900ET Automatic Weather Station features a built-in data logger that stores your measurements in a fail-safe, non-volatile memory at user-defined intervals - until you transfer the data to your PC. Select measurement intervals of 1, 10, 15, 30, or 60 minutes. A 30-minute interval will record for 183 days before the station's memory is full.
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. |

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.

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. |
