Product Description

Apogee MQ-501 sensors are calibrated through side-by-side comparison to the mean of four transfer standard sensors under T5 cool white fluorescent lamps. The transfer standard sensors are calibrated through side-by-side comparison to the mean of at least four quantum sensors under T5 cool white fluorescent lamps traceable to the National Institute of Standards and Technology (NIST).

Accurate, Reliable Light Measurement

With full-spectrum detection of 389 to 692 nm and a high-sensitivity quantum (PAR) sensor, the MQ-501 provides quick and accurate PPFD readings essential for optimizing plant growth conditions. The meter's NIST-traceable calibration ensures data you can trust for both research and practical agricultural applications.

Built for Versatile, Rugged Use

Designed to withstand tough environments, the MQ-501 features a UV-stabilized polycarbonate sensor and IP65 protection. Its portable, lightweight design, and optional analog output make it ideal for field and laboratory work alike, across greenhouses, farms, and horticultural centers.

Effortless Operation and Maintenance

A simple 4-digit LCD interface presents results instantly, while minimal power consumption and a battery life of up to one year minimize maintenance. Cosine correction and NIST traceability guarantee ease of use without compromising on accuracy or compliance.
