Hanna Gro'Chek Portable pH/TDS/EC/°C Met

This meter is identical to the HI 9813-0, with the addition temperature measurement and Hanna's new Cal-Check calibration feature. This feature enables the grower to verify that the electrode is clean and calibrated in just seconds.

Hanna Gro'Chek Portable pH/TDS/EC/°C Meter (HI 9813-6) - pH, EC, TDS and °C in the Palm of Your Hand!

Four Meters in One The portable HI 9813-6 is an extremely convenient tool, measuring four of the most important parameters in agriculture with a single instrument!
One Probe for pH, EC, TDS and °C! The rugged and replaceable HI 1285-6 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 advanced HI 9813-6 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 9813-6 allows you to measure pH, EC (conductivity) and TDS with just one instrument! The specially engineered HI 1285-6 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 9813-6 is an excellent addition to your growing tool chest.

HI 9813-6 is supplied complete with HI 1285-6 probe with Cal-Check feature, pH 7 calibration sachet, 1413 uS/cm and 1500 ppm calibration solution sachets, cleaning solution sachet, Cal-Check solution sachet, batteries and instruction manual in a protective case.

NOTE: BGH highly recommends the use of Electrode Cleaning and Electrode Storage Solution with any meter. Customers have sent their defective meters back only to have them returned because there was nothing wrong with them - all they needed was a good cleaning. By using Electrode Storage Solution you will lengthen the life of the electrode (which is warranteed for only six months) and minimize the frequency in which you will have to clean it.
