The CGR4 longwave radiation meter is an optimal scientific research grade measuring instrument. Its specially designed crescent dome structure enables measurement within a 180 degree viewing angle range, with negligible directional response error. The outer side of the dome is coated with a hard carbon layer, which makes the spectral response smooth and also protects the silicon surface. In addition, the dome structure gives it excellent thermal stability, coupled with the instrument body, which can meet the needs of dome temperature measurement or dome shielding. CGR4 can be equipped with CVF 3 ventilation device to further improve performance. The yellow signal cable is equipped with a waterproof socket, and there are multiple options for the pre wired length between it and the waterproof plug. The internally integrated bubble level has been raised to the top of the housing, allowing you to view the bubble level without removing the redesigned buckle sunshade, while also covering the connector. The contacts of the connector are gold-plated, making it easy to exchange and recalibrate. The drying box used is a screw in type, which is easy to remove and fill. The bag also contains a desiccant for replacement.
