Outdoor Humidity & Temperature Transmitters – HOTT-Series

Description

The HOTT-Series Outdoor Humidity & Temperature Transmitters are designed to measure and monitor relative humidity and temperature in outdoor environments. These transmitters convert measurements into standard signals of 0-10 Vdc or 4-20 mA, making them versatile for a variety of control systems.

Available with or without an LCD display, the HOTT series provides reliable performance with user-adjustable settings and durable construction suitable for harsh environments.
