The AT-2 Air Temperature Sensor delivers high-precision ambient temperature measurements for environmental monitoring systems. Designed for meteorological stations, agricultural applications, and HVAC control, it features a radiation-shielded probe for minimized solar error. With ±0.2°C accuracy, IP67-rated housing, and wide operating range (-50°C to +80°C), this sensor ensures reliable data collection in harsh outdoor conditions. Compatible with most data loggers via analog/digital outputs. Ideal for long-term deployments requiring maintenance-free operation and NIST-traceable calibration. Includes 5m cable with UV protection.
Precision Temperature Monitoring Solution
The AT-2 Air Temperature Sensor provides laboratory-grade accuracy for critical environmental measurements. Engineered with a passive radiation shield, it minimizes solar heating effects that compromise standard sensors, delivering true ambient temperature readings even in direct sunlight.
Robust Field Performance
Encased in weatherproof stainless steel with IP67 protection, the AT-2 withstands extreme conditions from desert heat to arctic cold. Its naturally ventilated design prevents moisture buildup while maintaining rapid response to temperature fluctuations - essential for meteorological applications and climate studies.
Seamless Integration
With configurable 0-1V, 0-5V, or 4-20mA outputs, the sensor connects effortlessly to LSI Lastem's data loggers and third-party systems. The extended 5-meter cable (optionally upgradable to 100m) facilitates flexible installation across monitoring networks.
