E2218 is a humidity and temperature transmitter designed for industrial indoor and outdoor applications. Equipped with a fully calibrated and temperature-compensated digital sensor, it ensures accurate and stable measurements. With switchable analog outputs (0–10 V or 4–20 mA), RS485 Modbus RTU interface, and options for attached or remote probes, the E2218 provides flexible installation, reliable operation, and heavy-duty IP65 protection for harsh environments.
