  2. Specification (ALH Series) ALH-3EG • ALH Series Important Features • High resistance to a water • Low cost performance • Long term stability • Very low hysteresis • Fast response time • Small dimensions • Wide humidity operating range • Typical Applications • Air-conditioner • Humidifier-Dehumidifier • Automobile • Clean room • Food products • Humidity controller & Transmitter Electrical Characteristics ★ ±2%RH (at 25℃,60%RH) is available High Quality Low Cost

  3. Specification (ALH Series) ALH-3EG Mechanical Test Lead Bend StrengthThe humidity sensor is kept in the vertical direction and the leads should be bent 1 cycle in the direction of 90 degree of load applied 250g. No change in appearance or performance is allowed. • Lead strength testA loadof 1kg is applied to each lead in the vertical plane against the surface of the sensor for • 60 ±1 seconds. • No change in appearance or performance is allowed. • Drop TestHumidity sensor is dropped on to a wooden surface from a height of 1 m three times. • No change in appearance or performance is allowed. Reliability Test High Quality Low Cost
