Heavy-duty hygrometers in a rugged waterproof case provide excellent accuracy even under tough conditions without running the risk of damaging the circuitry or the batteries. Large and easy-to-read LCD with graphic symbols to identify operational mode.
Relative Humidity measurements in seconds through a thin film polymer capacitance sensor with compensation for any temperature effect. A perforated cap allows good air circulation while protecting the sensor. One meter spiral cable for hard-to-reach places. RH detachable probe can be changed without having to return the instrument for service. Both instruments provide a “Hold” key to freeze the displayed value. Besides Relative Humidity, No. 576-900-04 displays temperature and is supplied with a precalibrated interchangeable air probe. The temperature probes do not require recalibration and are available in a range of different shapes and sizes for almost any application. Applications: greenhouses, air conditioning archives, museums, computer rooms and in industry from paper to textile and photography to food. Power is 4 AAA batteries. Warranty: 2 years.
