Waterproof Portable pH/EC/TDS Meter
Shop Waterproof Portable pH/EC/TDS Meter Now >Application Driven Performance
Hydroponic growers are faced with many difficulties when performing analytical measurements. Humidity, electrical noise from ballast and pumps, and pH calibration to a single point that is also close to the expected value, all can be challenging in obtaining an accurate reading. The GroLine portable pH/EC/TDS meter uses a single probe designed with an amplifier in the pH electrode that helps eliminate electrical noise resulting in a fast and accurate pH measurement. The pH electrode also has a buffered salt solution in the tip of the pH electrode that is at a different value from a standard pH electrode. Using a different pH buffered solution will result in a dramatically different measurement value from pH 7 being displayed in the event there is a hairline crack in the electrode.
Quick Cal Mode
Quick Cal mode allows the user to perform a single point pH and EC/TDS calibration with one solution. Simply enter calibration mode and the meter will prompt to confirm calibration to pH 6.86 and 5.00 mS/cm.
Multiparameter Measuring Modes
GroLine portable meters offer both Conductivity (EC) and Total Dissolved Solids (TDS) measuring modes. The EC measuring mode has an expanded scale to measure up to 6.00 mS/cm while TDS measuring range is up to 3999 ppm using a 0.7 conversion factor.

with extractable junction
GroLine waterproof pocket pH/EC/TDS meter uses a cartridge design replaceable electrode that does not have any pins to align or that can be broken. Simply insert and turn to lock in place. The replacement pH electrode also has an extractable junction that is used to clear any clogging that occurs with use resulting in erratic and drifting readings.

pH Testers
Shop pH Testers Now >More Options, More Choices
GroLine pocket meters include versions dedicated to only measuring pH. Meters include a choice of either an economical pH meter with a replaceable pH electrode or a waterproof slim line version that is remarkably easy to operate with only two buttons: one for turning the meter on/off and the other for calibration.
Big on Features and Affordable
GroLine pH meters feature automatic calibration, stability indicator, and automatic shut-off. Each of these features has their own benefits but the end result is a high performance meter that provides a precision laboratory measurement at an affordable price.
Replaceable pH Electrode Option
GroLine pH testers include a version with a screw type replaceable electrode. Based on care and use, the typical pH electrode will last 1-2 years. Replacing the electrode allows for an extended life for the meter.

pH/EC/TDS Calibration Solutions
Shop Calibration Solutions Now >Quick Cal Dual-Purpose
Calibration Solution
With GroLine Quick Cal solution only one solution is needed to calibrate both pH and conductivity. This dual-purpose calibration solution is used with compatible meters with the Quick Cal mode or with pH and conductivity meters that calibrate to pH 6.86 and 5.00 mS/cm, respectively.
Supplied with Certificate of Analysis
All GroLine pH and Conductivity/TDS standards in a 230 ml bottle are supplied with a Certificate of Analysis (COA). The COA contains the information regarding the traceability of the solution to NIST traceability standard. Information includes Standard Reference Material (SRM) used for calibration, lot number, and date of production.
Right Size, Right Price
GroLine calibration solution is available in convenient 230 ml bottle size due to the frequency of use. Infrequent use would include users that calibrate and measure on a weekly or monthly basis. With infrequent use it is important that the solution be used within six months of opening the bottle. After that it should be changed out since the measurements will only be as good as the calibration solution, which degrades over time. For added convenience, the Quick-Cal Solution is also available in 20 ml sachets.

Cleaning and Storage Solutions
Shop Cleaning and Storage Solutions Now >GroLine Cleaning Solution
Maintaining a clean pH electrode is vital for not only in getting an accurate pH measurement but also ones that are drift free. Any coating to the sensitive glass bulb or clogging of the junction will impede the electrical circuit resulting in erratic and misleading readings. GroLine cleaning solution ensures the maximum performance from the pH electrode to provide readings that you can depend on.
GroLine Storage Solution
All glass pH electrodes need to be stored properly to guarantee an accurate calibration and to protect the pH electrode from premature failure. A few drops of storage solution will maintain the hydrated layer on the glass bulb and prevent the reference junction and electrolyte from drying out. GroLine storage solutions are specifically formulated to accomplish the task and maximize the life of the pH electrode.
