Hanna Gro’Chek Portable pH/TDS/EC Meter (HI 9813-0) – pH, EC and TDS in the Palm of Your Hand!
- Three Meters in One The portable HI 9813-0 is an extremely convenient tool, measuring three of the most important parameters in agriculture with a single instrument!
- One Probe for pH, EC & TDS! The rugged and replaceable HI 1285 probe has been specially designed with fast response technology and measures all parameters at the same time.
- Specifically Designed The EC range has been extended and in the TDS range, the advancedHI 9813-0 uses the 4-4-2 conversion factor for growing applications.
This meter is a versatile, easy to use portable instrument engineered for use with all growing applications.
The convenient HI 9813-0 allows you to measure pH, EC (conductivity) and TDS with just one instrument! The specially engineered HI 1285 probe is interchangeable and the pH electrode utilizes a cloth junction and gel electrolyte which are particularly suitable when used in fertilizer solutions. This probe has also been designed with Hanna’s Fast Response Probe (FRP) technology to allow quicker reaction time to changing conditions. Calibration is reduced to one point in the pH mode, and one point in the EC/TDS mode. EC/TDS measurements are automatically compensated for changes in temperature. The meter has a Battery Error Prevention System (BEPS) which will not allow readings when the battery level is too low for accurate measurements. With all these features HI 9813-0 is an excellent addition to your growing tool chest.
HI 9813-0 is supplied complete with HI 1285 probe with 1 m (3.3′) cable, pH 7 buffer (20 mL), 1.41 EC and 1500 ppm calibration solutions (20 mL each), 9V battery and instruction manual. |

pH 7.0 Calibration Solution – 8 oz
We recommend that you calibrate you pH meter weekly. Most meters can be calibrated with 7.0 and 4.0 buffers. It is not recommended to reuse calibration solution once it has been used, it is no longer sterile. Pour a small amount into a shot glass and and place your meter or probe inside the glass for calibration. Suitable for all makes and models of pH pens and meters.
