Easy to use, just hang the Gro’Chek TDS Meter (with 0.7 TDS Conversion Factor) above the sample to be monitored or take it with you for on-site measurements. The probe, built for horticulture and hydroponics applications, compensates for temperature variations automatically, is very stable and requires little maintenance.
Ideally suited for indoor growers, this water-resistant TDS meter features housing and cable connections that have been sealed against vapor and high humidity conditions. In addition, false readings due to low batteries as well as frequent battery changes are NO longer an issue with the HI 983301N as it includes a 12-volt power supply.
