Wireless Temperature & Humidity Sensor with Display and Probe

NEO-1DP is a sensor and data logger with a display that wirelessly monitors temperature, humidity, VPD, heat index, and dew point for up to 3+ years on battery power. The base unit mounts outside freezers or harsh environments — protecting the screen and battery — while the probe reaches the monitored space.
