• 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.

 

• TEMPERATURE and RELATIVE HUMIDITY mini data logger with/no display
• Selectable storage interval 1-5-10-15-30 sec/min, 1 hour.
• Storage of 120,000 reading per channel,
• 8mm 3 ½ digit LCD display.
• IP54 protection degree.

• suitable for sound level meters (portable and laboratory) and acoustic stations
• class 1 according to IEC60942:2003 with LCD display.
• ISO 9001 calibration report included.
• 1000Hz frequency allows calibrating sound level meters with any weighting

 

• Bench-top pHmeter-Conductivity meter-Thermometer with back-lighted display,
• to measure pH, mV, ORP by pH, redox, separated reference electrodes, one input for a pH/temperature combined probe,
