Hanna Instruments, Primo 4: Primo 4

• Accurately measure TDS and conductivity
• Detached probe with long lead ideal for hard-to-reach places

This series of Primo testers has been designed for those hard-to-reach places where standard testers are not particularly suitable. The specially designed conductivity/TDS probe, supplied with the Primo series, has a 1 m cable. This helps insertion in inaccessible or low level places without the operator having to get into inconvenient positions merely to take a reading. The automatic calibration together with the convenience of the HANNA instruments ^® 20 mL sachet solutions make frequent calibration easier, which translates to better accuracy. Primo compensates for temperature automatically. Primo 4 reads EC from 0 to 10.00 in one hundredths of mS/cm (EC).
