PPM-712

M-712 is a continuous PM monitor for measuring both PM2.5 and PM10. Black
carbon mainly attributed from diesel emissions is also measured, simultaneously.
It's notable that SmartCalc function. SmartCalc evaluates PM2.5 concentrations
to ‘reference’ concentrations with high equivalence of FRM from ‘real’ concentrations under ambient condition.

PM-712 is designed to measure both fine (PM 2.5 ) andcoarse ( PM 10-2.5 ) fractions in PM 10 using a virtual
impactor, simultaneously. PM-712 also measures theblack carbon mainly attributed from diesel emissions
using OBC (optical black carbon) sensor. (Simple PM 2.5
type is selectable by product code PM-712-00.)

PTFE tape filter that has few effects by moisture and gas
adsorption.
Easy operation by large color LCD touch panel.
USB memory is available for data retrieve.
Large capacity memory stores measuring data for 1 year.
Optional cover tape roll protects sample spots for
speciation analysis.

KIMOTO realized the precise measurement of PM 2.5
with high-equivalence of FRM by the unique function“SmartCalc” born from our rich experiences. Using thisfunction, ‘real’ PM 2.5 concentrations under ambient condition ar e evaluated ‘reference’ concentrations of FRM
after aging for 24 hour with 35%RH.
