The HI 98309 Ultra Pure Water Tester is a handheld ultra pure water tester produced by Hanna Instruments. It is mainly used to measure water conductivity. The measurement range is 0.000-1.999µS/cm. The instrument has high measurement accuracy with a measurement error of ±2% f.s. It is suitable for ultra pure water measurement in laboratories and industrial production.
The HANNA HI 98309 is an Ultra Pure Water Tester designed to measure conductivity in the range of 0.000 to 1.999 uS/cm with a resolution of 0.007 pS/cm. The device operates using four 1.5V alkaline batteries and features a Battery Error Preventing System (BEPS) to avoid erroneous readings due to low battery levels. It is factory-calibrated with freshly prepared low-conductivity solutions.

Refer to the provided table which correlates UPW readings in uS/cm to equivalent resistance in MegaOhm.
No, calibration solutions in the UPW range cannot be supplied due to their high instability.
Use a 1.500 xuS/cm solution prepared by a qualified laboratory and adjust the calibration trimmer on the meter side.
