HI9814 GroPro Waterproof Portable pH/EC/TDS/Temperature Meter

HI9814 GroPro Waterproof Portable pH/EC/TDS/Temperature Meter

The HI9814 is a slim, lightweight, and waterproof portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single amplified probe. The meter operation is simplified with two buttons. One is used for on/off and for calibration while the other is used to switch between the measurement modes. The HI9814 has advanced features including an selectable EC to TDS conversion factor (0.5 – 500 ppm and 0.7 – 700 ppm).

Details

The HI9814 portable meter features a large multi level  LCD which displays both pH, EC or TDS and temperature readings simultaneously. The pH readings are displayed with a 0.01 resolution and 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 HI9814 is from 0.01 to 6.00 mS/cm and TDS is from 0 to 3000 ppm using the 0.5 conversion factor. The EC to TDS conversion factor is selectable 0.5 (500) and 0.7 (700 ppm). A built in temperature sensor allows for automatic temperature compensated measurements of EC and TDS.

 The HI9814 has many advanced features that are found in more expensive portable instrumentation including automatic calibration, buffer/standard recognition and temperature compensation. The LCD screen has indicators for calibration status and stability, as well as on-screen tutorial messages.

The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.  The supplied HI1285-7 is a  polypropylene body, amplified pH electrode with a built-in EC/TDS and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and sources of electrical noise include circulating pumps, motors and ballasts for grow lights.

The HI9814 is a versatile meter designed for hydroponics, greenhouse and agriculture applications.

Simplified 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 once QUICK CAL is displayed. Once both pH and  EC are calibrated CAL OK is displayed and the meter exits to measurement mode.

HI1285-7 polypropylene body amplified pH electrode with built in EC/TDS and temperature sensors

The HI9814 is supplied with an amplified polypropylene body pH/EC/TDS/temperature probe. The built in amplifier will reduce the effects of electrical noise on the high impedance pH measurement. Examples of sources of electrical noise include circulating pumps, motors and ballasts for grow lights.

Features at-a-glance

  • 3 sensors in a single probe

pH electrode – Preamplified for resistance to electrical noise including that generated by pumps and ballast

EC/TDS sensor – amperometric two pole design

Temperature – NTC sensor for accurate temperature measurement and compensation

  • Waterproof

Designed to withstand the humidity of a growing environment
  • Wide pH Range

pH range is from 0.00 to 14.00 pH
  • 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
  • Automatic Temperature Compensation
All readings are compensated for variations in temperature
Temperature displayed in oC or oF along with pH, EC or TDS reading
  • Stability indicator

Meter displays a clock tag that will disappear when the reading has achieved stability
  • HOLD button

Freezes reading on the display to allow recording of measurement
  • BEPS (Battery Error Prevention System

Meter will automatically shut off if there is not enough power to get an accurate measurement
  • Battery % level at startup
  • Low Battery Indicator
When the level is below 5%, the  battery symbol on the LCD blinks to indicate a low battery condition.
  • Auto-off
Selectable time before meter will automatically shuts off to conserve battery life. Options are after 8 minutes, 60 minutes , or disabled.
