Air Flow Capture Hood NACH-200

Air Flow Capture Hood NACH-200 is a multipurpose electronic air balancing instrument primarily used for efficiently taking direct air volume readings at diffusers and grilles. Detachable micro-manometer is used with optional probes for increased flexibility in multiple measurement applications and a nylon cloth cover is held by the support rod. Its average amount of wind is correct, fast and simple. It is widely used in measuring the in-out wind of the air-conditioning and the purification technology so that the systems can be administered and their parameters are adjusted automatically. It adopts the overseas vanguard technologies of the similar products. It works with a pressure connection of 1/4 in. (6.35 mm) OD straight ports with barbed ends for use with 3/16 in. (4.76 mm) ID flexible tubing. The working temperature is 5 to 35 C with the accuracy around 0.5 F ( 0.3 C).
