Introduction GZZ2-07 series radiosonde are -1, -2 in two models, September 1999 in large quantities of high-altitude meteorological observation site equipment., GZZ2-07-1-type sonde is the independent development, China's first anti-frequency interference with the radiosonde With dedicated ground demodulator, Can effectively overcome or reduce the impact of co-channel interference. The product obtained in the 2001 third prize of Shanghai Science and Technology Progress. ZZ2-07-2 type radiosonde be compatible with 701,701 A, 701C weather radar These two products can replace GZZ2-05 type radiosonde, have a narrow spectrum, frequency drift is small, output power, the answer pulse stability, and dynamic operating voltage range, high-altitude release a high success rate and so on. Main Specifications: Measurement range and accuracy: Temperature: +50 °C ~ -90 °C ≤ 0.7 °C Pressure: 1050 ~ 10hPa ≤ 2hPa Relative Humidity: 0 ~ 100% RH ≤ 5% RH Electrical properties: Transmission frequency: 400MHz ± 3MHz Transmitting power: ≥ 400mW Answer percentage: ≥ 50% Sub-carrier frequency: 32.7kHz Stop vibration voltage: ≤ 15V
