- 1 or 2 pyranometer with accuracy at ±10W/m2;

- accumulative solar irradiance calculation;

- 1 or 2 flow meters (ultrasonic, also accept other type flow meter that customer required)

- data collection speed: total 3s query;

- data collection accuracy: 24Bit A/D transducer with Auto-compensation of Temperature Drifts and Time-varying Drifts;

- anemometer: start at ≤0.5m/s; accuracy ±0.3m/s;resolution0.1m/s

 

Functions

 

Solar Thermal Application:

- daily and accumulative system heat gain for solar hot water system, solar heating and cooling system;

- system efficiency and heat loss coefficient;

- collector efficiency and heat loss; generate solar collector efficiency curve according to China or Europe or Australia standard;

- comparative testing for two collectors or systems;

- auto acquisition of solar irradiance, flow rate, temperature and wind speed, which can be displayed in table or graph, it can also collect other inputs as customer request.

Auto-calibration of temperature sensor: enable the accuracy;

Calculation: daily and/or accumulative heat gain, efficiency

Features

- Able to work independently, can be accessed via internet (option);

- 2GB SD card to save data;

- 5.7” touch screen to display data and operation settings as below figures illustrated (Interface can be in English or other languages).
