The Weather Balloons are produced by rotational molding of natural rubber.

Their uniform wall thickness prevent premature blowouts, and they are ozone resistant. Reinforced necks allow use in strong winds without tearing. Each balloon is inflated, inspected, and tested before being dusted and sealed in a moisture-proof polyethylene bag. They may be stored up to 7 years if kept in a cool, dark room. No pre-flight conditioning is required. Weather Balloons are not returnable.

Measures temperature, humidity, barometric pressure, and dew point

Relative humidity range is 10.0 to 95.0% with a resolution of 0.1% and an accuracy of ±3% RH mid-range to ±4% RH elsewhere. Temperature range is 32.0 to 122.0°F and 0.0 to 50.0°C with a resolution of 0.1° and an accuracy of ±1°C. Dew point range is 13.5 to 120.1°F and –25.3 to 48.9°C with a resolution of 0.1°.

Barometer measures pressure in 3 different units: Inches of mercury (inHg) from 0.29 to 32.48 with a resolution of 0.01, millibars (hPa) from 10.0 to 1100 with a resolution of 0.1 and 1 hPa, and millimeters of mercury (mmHg) from 7.5 to 825.0 with a resolution of 0.1 mmHg. Accuracy is ±4 hPa. User selectable dual display shows humidity/temperature, humidity/dew point, barometer/temperature, or barometer/humidity.

Lightweight and compact

Compact design features an electronic capacitance polymer film sensor not affected by condensation. Tough ABS plastic housing and water-resistant design with O-ring seal and membrane keypad assure a long life in severe lab or harsh plant environments. HOLD button freezes the reading on the display. High contrast 3/8-inch-high LCD digits are easy to read. At the press of a button, unit recalls minimum/maximum readings.

To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Rugged ABS plastic case is 1-1/2 inch diameter x 8 inches; weight is 5 ounces. Supplied with a Traceable® Certificate and four AAA batteries. Replacement battery Cat. No. 1105.
