CPS sonde (Cloud Particle Sensor)

CPS （Cloud Particle Sensor） sonde can directly measure atmospheric airborne particle (cloud particle, volcanic ash and so on.). CPS sonde　is used with combing to RS-11G. The data is received, processed and output by RD-08AC system. Small size and low price are realized by using of pollen sensor technology

HYVIS : HYdrometeor VideoSonde

Balloon borne HYVIS is in-situ measuring instrument to capture Upper-air cloud and/or ice crystal particles. HIVIS, connected with a GPS radiosonde, takes in ambient particles with sizes ranging from a few dozen μm to hundreds μm during ascension.

Radioactivity sonde

Radioactivity Sonde measures the vertical profile of both β and γ radiations together with temperature, humidity, height, wind speed and wind direction.

MTR-08 Temperature Reference Sensor for Upper-air

Temperature sensor with world's fastest response time for Upper-air observation It can capture the weather condition which operational sonde cannot measure because temperature with 0.01℃ resolution can be measured 16th a second

MDSS : Dropsonde Receiving System

iMDS-17 Dropsonde is used for typhoon observation and the observation data contributes to improve typhoon forecast. iMDS-17 has a temperature sensor, a humidity sensor, a pressure sensor, and a GPS module. Due to compactness and light weight, aerodynamic drag decreases its descending speed, even without a parachute. This means parachute failures can be avoided, and thus realizing a stable operation.

MCD-10 CO2 Sonde

World-first Balloon-born CO2 sensor was developed to measure the vertical profile of CO2 in any place in the world under any weather conditions. It anytime capable to measure CO2 precisely with not affected by weather condition and day& night

GPS Radiosonde Ground Receiver System RD-18

GPS Radiosonde Ground Receiver System efficiently responds to operator’s requirements for Upper-air sounding operation. The lightweight and simple system allows easier installation.

RD-08AC GPS Sounding System

RD-08AC is a low-cost solution for Upper-air sounding for academic research users.　The system offers selective functions that fully support your research work. 240 minutes of flight timeframe covers an entire flight process from pre-flight through balloon burst. RD-08AC will support to expand your research horizons.

Automated Radiosonde system (ARS)

Canister type ARS allows to adjust the number of Radiosonde & balloon to be loaded. It can release operators from mid-night-early morning sounding, dangerous H2 gas inflating works, etc.
