overview
TGMP343 can simultaneously output filtered data and raw measurement data. It can also compensate for measurement values using internal temperature measurements and user set relative humidity, pressure, and oxygen values.
GMP343 can provide tools for precise on-site measurements. For on-site portable use, equipped with a dedicated MI70 handheld device, MI70 can be used as a display, communication, and data recording device.
Each GMP343 can be calibrated using gas with an accuracy of ± 0.5% at concentrations of 0 ppm, 200 ppm, 370 ppm, 600 ppm, 1000 ppm, 4000 ppm, and 2%. Calibration can also be performed at temperature points of -30 ° C (-22 ° F), 0 ° C (32 ° F), 25 ° C (77 ° F), and 50 ° C (122 ° F). If necessary, customers can use the Multi Point Calibration (MPC) function to recalibrate the instrument, providing up to 8 user-defined calibration points.
