Apogee Instruments - MI-210: Research-Grade Infrared Radiometer with Handheld Meter

Brand: Apogee Instruments

The Apogee MI-210 is a research-grade infrared radiometer with a handheld meter that measures plant canopy and leaf surface temperature without contact. Canopy temperature is the direct input for accurate VPD and plant water-status decisions.

Unlike air temperature, canopy temperature reflects how the plant is actually transpiring; measuring it lets growers detect stress, refine irrigation, and steer crops precisely.

Key Features

• Non-contact canopy/leaf surface temperature, 8 to 14 um atmospheric window
• Research-grade uncertainty +/- 0.2 C from -30 to 65 C
• Handheld meter with real-time readout
• NIST-traceable with calibration certificate
• Built and calibrated in Logan, Utah; NIST-traceable, made in the USA, and backed by an industry-leading 4-year warranty.

Why Choose This Model

Apogee infrared radiometers are the standard for non-contact canopy temperature in plant research and precision growing.

Ideal Applications

• Canopy temperature for VPD and crop steering
• Plant water-status and stress detection
• Phenotyping and greenhouse research
