Portable Meters

A variety of portable meters are available to measure pH. Many portable meters are made specifically for the hydroponics market. These meters have CAL Check functionality with some of them using specialized pH probes that will identify a probe that have damage to the internal glass stem or hairline fracture in the glass sensing bulb. A standard pH electrode will display a frozen reading of pH 7 when there is damage. The meters with CAL Check will display a reading close to pH 4. This is very beneficial to users that perform a single point calibration to pH 7 and expect to have results that are close to pH 7.

Also included in this category are multiparameter meters that can measure conductivity and/or TDS.

Testers

A variety of testers are available including a version that allows for the direct pH measurement in rockwool and other soiless media.

Monitors

The monitoring & control of nutrient solutions is critical to successful propagation and optimization of plant growth. Different plant species have an optimal pH for nutrient uptake and growth.

Monitors offer the ability to continuously measure and display pH. Multiparameter versions are also available that display EC and/or TDS in addition to pH.

Benchtop Meters

Benchtop meters include a multiparameter photometer version made for measuring nutrients in a solution. The benchtop photometer hasa digital probe input that allows it to be used to take a pH measurement with a standard pH electrode.

Electrodes

In this category are the replacement pH probes for hydroponic pH and multiparameter meters.

Calibration Solutions

In this category are pH calibration buffers including our GroLine buffers that are supplied complete with a certificate of analysis. The pH calibration buffers are available in a variety of sizes from single use sachets to bottles.

Also included in this category are the Quick Cal solutins used with some of the hydroponic pH meters. These solutions are formulated for single point calibration of both pH and EC.

Maintenance Solutions

Maintenance solutions include both cleaning, storage, and probe refill solutions.

Cleaning solutions are available that are made specifically for agricultural use.

Accessories

Accessories include shockproof rubber boots used with the portable meters. These boots give additional protection from accidental drops and provide for a more tactile feel when holding the meter.
