Type: Hydroponics
Subtype: pH/EC/TDS
The HANNA pHel pH Tester is specially designed for the requirements of hydroponic use. With easy two-point calibration and a battery life of 1,000 hours, the pH Tester reliably provides accurate measurements. Pocket-sized with a slim probe engineered for testing in smaller spaces, this sturdy pH tester measures pH from 0.0 to 14.0 with a resolution of 0.01 and accuracy of ± 0.2, and its display updates automatically with minor changes in the pH. Includes electrode, batteries and instructions. Carries a two-year warranty on the meter and a six-month warranty on the probe.

Subtype: pH/EC/TDS
Ensure the purity of the water produced by the RO water filtration system with the HANNA Primo TDS (total dissolved solids) Tester. This microprocessor-powered instrument provides readings of total dissolved solids that are accurate enough to meet the exacting standards of water-quality professionals, and its big LCD screen and single-button functionality make obtaining and reading the results a snap. It also powers down automatically when it goes unused for five minutes, and includes batteries and instructions. Primo measures TDS from 0 to 1999 parts per million (ppm); accuracy ± 2 percent F.S.

Type: Hydroponics
Subtype: pH/EC/TDS
HANNA PET EC Solution calibrates meters in moments. The conductivity value at 77 degrees Fahrenheit is 1413 µS/cm. Comes in FDA approved opaque bottle to prevent light from damaging the solution. 230 ml size.
Type: Hydroponics
Subtype: pH/EC/TDS
This pH-EC-TDS Meter combines pH and ppm sensors in one probe on a 3' cable. It also displays mineral ion concentration in terms of electrical conductivity (EC) as an alternative to ppm. Features include automatic temperature compensation and calibration knobs (no screwdriver required). The included 9V battery will last for 150 hours.
Type: Hydroponics
Subtype: pH/EC/TDS
Reliable and ergonomically designed, the HANNA pHep pH Tester features a nonclogging fiber junction, simple two-point calibration and measures pH from 0.0 to 14.0, with a resolution of 0.01 and ± 0.1 accuracy range. Unit includes electrode, and batteries. This tester is protected by one-year manufacturer's warranty.
Type: Hydroponics
Subtype: pH/EC/TDS
Manufactured by Hanna Instruments to provide accurate readings to the pH-EC-TDS Meter with F.S.T. Technology, the multi-pin replacement <STRONG>Probe </STRONG>is covered by a six-month manufacturer's warranty.
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.
