GroLine Hydroponic Waterproof Pocket pH/EC/TDS/Temperature Tester
The GroLine pH and TDS water tester features a large multi-level LCD that displays both pH, EC or TDS and temperature readings simultaneously. The pH readings are displayed with a 0.01 resolution and with an accuracy of +/-0.05 pH, while the EC and TDS readings are displayed with a 0.01 mS/cm and 10 ppm (mg/L) resolution and 2% full-scale accuracy. The EC range of the this unit are from 0.01 to 6.00 mS/cm and TDS is from 0 to 3000 ppm using a 0.5 conversion factor. The GroLine pH and TDS water tester also offers the option to use a 0.7 (700 ppm) EC to TDS conversion factor. An exposed temperature sensor allows for rapid temperature compensated measurements of EC and TDS. The LCD screen has indicators for calibration status and stability. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. The GroLine pH and TDS water tester is a versatile pocket meter designed for hydroponics, greenhouse and agriculture applications.
Easy One-Button Calibration
One or two-point pH calibration is automatic to a pre-programmed buffer set (4.01, 7.01 and 10.01) or single point pH and EC calibration with the Hanna Quick Cal calibration solution. To perform a quick cal calibration, simply press and hold the left power/mode button while in measurement mode for three seconds and let go to enter calibration mode. Once both pH and EC are calibrated "CAL OK" is displayed and the meter returns to measurement mode.
Replaceable pH electrode
The GroLine Hydroponic Waterproof Pocket pH/EC/TDS/Temperature Tester is supplied with the HI73127 replaceable pH electrode. This electrode features an extractable junction that can be pulled 1/8" out to clear any clogging that results in drifting and erratic readings.
One Meter - Three Sensors
- pH electrode with extractable junction
- Amperometric EC/TDS sensor
- Exposed temperature probe for faster EC/TDS readings
Selectable EC to TDS conversion factor
- Choice of either a 0.5 or 0.7 conversion factor
- 0.5 (500 CF) conversion factor is for an EC reading of 1000 μS/cm = 500 ppm
- 0.7 (700 CF) conversion factor is for an EC reading of 1000 μS/cm = 700 ppm
HOLD button
- Freezes reading on the display to allow recording of measurement
Low Battery Indicator
- If battery level drops below 5%, the battery symbol on the LCD blinks to indicate a low battery condition.
Waterproof
- Designed to withstand the humidity of a growing environment
Automatic Temperature Compensation
- All readings are compensated for variations in temperature
Temperature displayed in °C or °F along with pH, EC or TDS reading
BEPS (Battery Error Prevention System)
- Meter will automatically shut off if there is not enough power to get an accurate measurement
BEPS (Battery Error Prevention System)
- Meter will automatically shut off if there is not enough power to get an accurate measurement
Warranty
- This meter is warranted for a period of one year against defects in workmanship and materials when used for their intended purpose and maintained according to instructions. The electrode is warranted for a period of six months.
