This ventilated psychrometer is a standard for measuring temperature and humidity, and uses a platinum resistance thermometer (Pt100) instead of the conventional glass thermometer.Accurately measures dry and wet bulb temperature and displays air temperature, humidity and dew point temperature.The body is designed to minimize the effects of solar radiation and radiation.

High accuracy measurement using platinum resistance thermometer (Pt100Ω) for dry bulb and wet bulb without using mercury thermometer
Wet-bulb temperature is measured by moistening the non-woven fabric sprinkled on the sensor with the attached dropper.
Calculates and displays dew point temperature (mode switching display)
● Meteorological instrument certification acquisition is possible
● A / D conversion circuit calibration function
● Measurement results are recorded on the microSD card mounted on the main unit.
● Driven by 4 AA batteries (alkaline batteries, approximately 7 hours at room temperature)

Water temperature transmitter R900 / ground temperature transmitter R903

This road surface thermometer is embedded in the road surface so that it can be measured in consideration of representativeness.Two transmitters are installed in consideration of damage caused by vibration and the trouble of replacement.

● The mold material of the sensitive part is made of the same material (SB mortar material) as the road surface.
● Designed to be flush with the road surface so that it does not become a traffic obstacle when buried in the road surface.
● The front / rear and 2 sensors are mounted in case of failure.
● The sensory part can obtain the Japan Meteorological Agency temperature test.

By using a platinum resistance thermometer in the sensing part and attaching it to the float, the water temperature at a certain position can be measured from the water surface regardless of the water level.

● The float is designed to be strong against impact and hard to break.
● Surface water temperature can be measured.
● Stable measurement with little secular change.

This water temperature gauge uses a crystal element for the sensitive part, utilizes the characteristic that the frequency changes depending on the water temperature, and transmits the frequency to the receiver on the land part by radio.The receiver demodulates and performs arithmetic processing, analog recording, and at the same time external output.

● There is no hassle of wiring work.
● Even if the water level fluctuates, the water temperature at a fixed position from the surface layer can always be measured.
● Since a crystal element is used, the accuracy is good and there is no secular change.
● A battery alarm is sent.
● Measurable up to 4ch.

This is a humidity sensor that uses a highly accurate and highly reliable polymer film in the detection section. Capacitance change of polymer film with respect to humidity is regarded as change of transmission frequency, and humidity is measured with high accuracy in the whole range of 0 to 100%.

● High accuracy of humidity measurement ± 2% (at 23 ℃)
● Output relative humidity and temperature as serial signals (RS-485)
● Meteorological Agency certification can be obtained (humidity only, temperature is not subject to certification)
● Temperature measurement is possible at the same time (Pt100 sensor)
● Analog output is possible for both humidity and temperature.
● The detector and the main unit can be separated (only the detector can be replaced)

Utilizing the capacity change during water absorption by the polymer thin film, the humidity change is accurately captured and the humidity value is output as an analog signal or RS485.For atmospheric observation, store it in a Stevenson screen or a ventilation shelter to prevent direct sunlight.

● Excellent high accuracy, long-term stability and hysteresis.
● Highly accurate measurement from 0 to 100% RH is possible despite a wide range of specified temperatures.
● JMA certification can be obtained.

A capacitive hygrometer with a polymer polymer sandwiched between electrodes in the sensitive area.When a DC power supply is applied to the sensor, a voltage output proportional to the humidity is obtained.

● Excellent response.
● Small and lightweight.

A thermometer transmitter and a hygrometer transmitter are incorporated in one shelter, and a sirocco fan is used to forcibly ventilate the transmitter to eliminate the effects of sunlight.You can freely combine the type of transmitter to be incorporated and the conversion module to be incorporated.

● Sensing area test is provided for both temperature and humidity.
● Ventilation amount to thermometer transmitter and hygrometer transmitter is changed to reduce the influence of radiation and fog.
● Ventilation stops even during strong winds and keeps ventilation speed without backflow.

The radiant heat of the sun is prevented by putting the thermometer transmitter in a stainless steel triple cylinder and ventilating it.Unlike the Stevenson screen, there are few restrictions on the installation location, and you can measure correctly even when there is no wind.

● Small, lightweight and made of stainless steel.
● Structure with backflow prevention.
