Sursa sunet cu generare semnal audio pentru calibrari nivel acustic Clasa I/II Delta Ohm HD9101 HD9102

• The pyrheliometer LP PYRHE 16 First Class Pyrheliometer according to ISO 9060 classification
• is an instrument for direct measurement of solar irradiance (Watt/m2).
• The receiving surface must be positioned (via a solar tracker or else) perpendicularly to sun’s rays.
• By using suitable diaphragms only the direct light reaches the surface of the sensor.
• According to WMO (Seventh Edition 2008) and ISO 9069 regulations, the pyrheliometer has a field of view of 5°.

 

• LP NET 07 measures the net radiation across a surface, from near ultraviolet to
• far infrared.
• The Net radiation is defined as the difference between the radiation that reaches the upper surface and the irradiation on the lower surface of the net radiometer.
• The surface of the upper receiver measures the direct solar radiation plus the diffuse one and the radiation at longer wavelengths emitted from the sky (clouds), while the lower receiving area measures the solar radiation reflected from the ground (albedo) and the radiation length wavelengths emitted from the earth.
• The instrument is designed and constructed to be used outdoors in any weather
• conditions.

 

• Determination of the anemometric quantities represented in diverse measurement units:
• wind speed and direction,
• U-V-W Cartesian components of speed,
• sound speed,
• sonic temperature
• 5 analogue voltage or current outputs, with different measuring ranges.
• RS232 and Multidrop RS485 Serial Communication interfaces.

 

• generator noise level 9101/HD HD 9102
• portable, battery-powered sound source,
• suitable for calibration of sound level meters (portable and laboratory) and acoustic measuring stations
• possible to calibrate directly microphones 1 / 2 "of mechanical dimensions conform to the requirements of IEC 61094-1
• the frequency of the sound signal at 1000Hz can perform calibration of sound level meters with any frequency weighting
• sound pressure level generated is independent of atmospheric pressure
• Ease of use allows the use even by unskilled personnel.

 

• pHmeter-Thermometer which measures pH, mV and temperature.
• Datalogger which stores the maximum, minimum, average value and can store up to 34,000 samples.
• RS232 C/ USB output for data transfer in real time to a PC or printer.
• Functions: REL, HOLD and auto power off which can be disabled,
• IP 67 protection degree.
