Gilian Challenger ® It is specifically used for calibrating occupational health sampling air constant current samplers or other sampling equipment. The measurement accuracy is 0.75% for real-time reading, with LCD display of volumetric flow rate and standard state flow rate, atmospheric pressure, and ambient temperature.

Challenger ® The core component is the Venturi flowmeter. Adopting aluminum alloy structure and streamlined integrated design, it is sturdy and durable. The wide range design can measure flow rates of 1-30 LPM

Each device comes with a NIST calibration certificate and is calibrated at both high and low flow rates.

Main features:

• Accurate flow calibration 1-30 LPM

• Wide temperature measurement range -30 ° C to 55 ° C

• Can display actual flow rate, standard flow rate, atmospheric pressure, and ambient temperature

• Easy to operate, integrated design

• Truly portable, battery powered
