Type: Hydroponics
Subtype: pH/EC/TDS
The Waterproof EC/TDS Tester is an easy to use, convenient meter. Graphite electrodes ensure accuracy, and are easily replaced with a new cartridge. This tester comes with a probe, batteries and electrode replacement tool to make maintenance easy. Stainless steel temperature probe provides fast and accurate measurement. The unit automatically figures calibration and temperature compensation, but the EC/TDS conversion factor and temperature coefficient are adjustable. The dual-level LCD display shows EC and TDS as well as F. or C. Unit features a prompt telling the customer when to take a reading and also when to freeze the display. The battery lasts 100 hours, and the unit automatically shuts off after 8 minutes. Range: EC - 0 to 3999 µS/cm; TDS - 0 to 2000 ppm. Accuracy: EC ±2% full scale, TDS ±2% full scale, temp ±5° C or ±1° F. This tester combines the convenience, accuracy and quality that customers need.

Type: Hydroponics
Subtype: pH/EC/TDS
The Hanna pH EC TDS Meter with F.S.T. Technology accurately conducts each respective test in one handy unit. The meter ranges are: pH from 0.0 to 14.0 with a 0.1 resolution, EC from 0.00 to 4.00 with 0.01 resolution, and TDS from 0 to 1990 ppm with a 1 ppm resolution. The accuracy is ±0.1 for pH; EC and TDS have an accuracy of ±2%. This meter features a fast-response probe, automatic temperature compensation, calibration knobs for one-point manual calibration and F.S.T. Technology that informs the user of a possible anomaly (such as a cable short circuit) that needs to be corrected by displaying a pH value close to 4 rather than 7, as is the case with similar instruments. There is also a “check” button with corresponding LED lights to indicate potential probe and electrode problems. The meter comes in a storage case with calibration, test and cleaning solutions; 9V battery; and detailed instructions.
