We are offering marmonix thermometer anemometer with infrared.The cfmcmm thermo-anemometer with infrared thermometer measures air velocity, air flow (volume), air temperature (with probe) and surface temperature (with the infrared function). The large, easy-to-read backlit lcd includes primary and secondary displays plus numerous status indicators. The infrared feature includes a laser pointer for convenient targeting. In addition, the meter can store 16 area setting dimension for easy recall. Proper use of this meter will provide years of reliable service.Max (top of lcd): max hold function engaged for the air temperature functionhold (top of lcd): data hold function engaged for the air temperature functionprobe temp: reminder that the top lcd digits represent air (vane) temperatureir temp: indicates that the larger lcd digits represent ir temperature measurementvel: indicates that meter is in air velocity modeflow: indicates that meter is in air flow modemax (bottom of lcd): max hold for the ir temperature and rh functionhold (bottom of lcd): data hold for the ir temperature function and rh functionoc of: temperature units of measurecfmcmm: airflow units of measureft2, m2: units for area dimensionsms, ftmin, kmh, mph, knots: air velocity units of measurex10, x100: multipliers for air flow readingsavg: air averaging moderecord: indicates that minmax function is running (top for temp, bottom for air)large lcd digits at center of display for relative humidity and ir temperaturesmaller lcd digits at top, right of display for probe temperature
