| HANNA Instruments GROCHEK Meters
Provide continuous digital pH or EC scale read-out, designed to meet the needs of growers in greenhouses and hydroponic applications. Completely sealed against vapors and humidity, so you can hang meter right above your sample to be tested for continuous measurement. Easy to clean and requires little maintenance. Select your own set-point and be alerted of an abnormal situation with a flashing LED alarm. Unit runs without interruption on 12 VDC power supply. | ||||||||||||||||||||
| Hanna Combo GroChek pH/EC/TD/Temperature Combo Hanna Model HI 991404 The new Combo GRO’CHEK from Hanna has a dual-level backlit LCD to give you instantaneous readings of pH/EC/TDS and temperature. Simply install the meter above the reservoir and insert the electrodes into the solution for continuous readings. The microprocessor provides automatic calibration, automatic buffer selection, automatic temperature compensation, adjustable ß and adjustable TDS ratio. Measurements are defined as 700 ppm = 1 EC. Range of pH is 0-14 and ppm is 0-2000. ●Waterproof ●Dual-level Backlit LCD ●Extra Large Display ●12V Power Supply

Hanna GroChek TDS Meter Meter comes with a probe that compensates for the temperature variation automatically. The probe is easy to clean and requires little maintenance. Measurements are highly accurate and the meters can be calibrated at one point. In addition, the TDS GroChek uses a specially devised formula which perfectly reflects the needs of growers. In fact, the common method of measuring TDS by multiplying the conductivity by 0.5 which is far off the mark in horticulture with high concentrations of phosphate, nitrogen, etc. |

Hanna GroChek EC Meter
Provides continuous digital EC scale read-out. This scale is the international Electro Conductivity scale. No alarm light. The EC scale is not linear to Parts Per Million. The new PPM meters for horticulture are being built to the specs of .7 to 1 or 700 PPM to 1 EC. For those who use the Conductivity Factor (CF) scale 1 EC = 10 CF. CF was created to eliminate tenths of an EC. Example: 1.5 EC = 15 CF. EC is multiplied by 10 to reference CF. | HY1791 $105.95 | ||||||||||||||||||
