Issue:

What are the operating temperatures for ION 7300 meter series?

Product line:

ION7300 Meter Series

Resolution:

Operation temperature of an ION7300 meter series (ION7300, ION7330, or ION7350) is -20°C to +60°C (-4°F to +140°F) ambient air, and is the same for both the Tropical and non-Tropical boards. In addition, Storage Temperature is 0°C (-22°F) to +85°C (185°F) and Relative Humidity is 5% to 95% RH non-condensing.

Note:

The ambient temperature is the actual surrounding temperature where a device operates. Tropicalized temperature isn’t a separate rating it means the device is built to handle tropical conditions like high humidity and corrosion, while still operating within the same ambient temperature range.
