pH Meters

Bluelab pH Pen

The ultimate handy solution for measuring pH and temperature!

Plants get their nutrient from minerals, but they can only get all the right minerals they need if certain conditions are right. Think of nutrients like a lock. pH is the key. A key factor that affects food uptake is whether your solution is acid or alkaline. We measure this in pH.

The Bluelab pH Pen also measures the temperature of the solution, as root health is vital to the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 – 22˚C or 65 – 72˚F is recommended.

The hand held pH pen provides a compact quick and handy way to manage the success of your crop to ensure maximum uptake of nutrients.

Teamed with our Bluelab ppm or EC Pen, you have a handy, convenient and accurate system for ensuring optimum plant growth and health.

Now isn’t that Handy!

• In hydroponics "pH" is an extremely important factor. When it is poorly monitored or controlled, plants can become sick or die. It is therefore recommended that pH is tested daily. Hy-Gen pH Up and Hy-Gen pH Down provide the grower with an added control in maintaining optimum pH levels and hence maximizing nutrient availability and plant productivity. A too high or too low pH can complicate the absorption of important nutrients such as iron, calcium, magnesium, etc.
• Generally the pH of the hydroponic solution should be 6.3. It is acceptable, however, to maintain the pH in the range of 6.0 to 6.5. For rockwool a lower pH of 5.8 to 6.0 is recommended. This allows for optimum nutrient solubility and availability.

HY-GEN® COMPLETE pH KIT is an easy and accurate way to keep track of the nutrient solution pH. The kit gives the added ability to adjust your pH using the pH UP and pH DOWN solutions provided. Adjusting the pH is quite easy and after some time and experience it becomes an art as you start to learn more about your plants and growing system.

The concentrated indicator solution allows you to obtain a reading by using just one drop in the test tube provided. The calibrated colour chart provided helps test your pH to within 0.5 of a pH unit. Testing and adjusting your nutrient solution regularly will ensure your plants are healthy and happy.

Testing and adjusting the nutrient solution pH is made easy with a HY-GEN Complete pH Kit. The kit comes supplied with a test tube, 1mL transfer pipette, 150mL pH Up, 150mL pH Down, colour chart and concentrated indicator solution. Testing only requires one drop of indicator.

• Simple To Use
• Accurate Colour Chart
• Concentrated Indicator Solution
• Only One Drop Required
• pH Up And Down Solution
• Multiple Tests
• Transfer Pipette For Easy Use

Our affordable and economical line of water monitoring equipment. The Milwaukee pH600 is a compact pH tester that has manual one-point calibration. These appeal to farmers on a budget and are designed for simple use.

Use and Care

All pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH pen tester will give you fast, accurate results for longer. So, be sure to order the Milwaukee pH Maintenance Kit code PH-Main at checkout time!  This will be needed to help clean and condition the pH electrode before use!

Here are our top four tips. 

1. Always store upright with the cap full of buffer or storage solution MA9015, not water.
2. Clean your pH Pen Tester regularly by soaking in cleaning solution MA9016.
3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.
4. Gently stir the Pen in the sample for a faster result.

• Fast, accurate results with digital LCD readout
• Easy measurement: just place the probe in the sample, gently stir and wait for the reading to stabilize
• Simple one-point calibration with an easy-to-use trimmer located on the back of the pH tester to protect from accidental splashes

pH Dropper – Test Kit

For reliable & fast pH readings

“Unlike electronic pH meters, there is NO complex or costly maintenance required with the pH Test Kit”

Super concentrated – ONE drop per test – approximately 800 tests.

pH range 4.0 to 8.0:  Many pH testers do not operate below pH 6 (See pH Control).

Produces fast pH readings:  Note that pH meter electrodes usually need to be left in the sample for several minutes before an accurate/ stable reading is produced.

Waterproof colour chart on side of bottle.

Perfect back-up for die-hard pH meter users.

Supplied with sturdy test tube.

How accurate is Flairform’s pH Test Kit?

When using a pH Test Kit, you will get accurate results every time. Even if electronic pH meters are properly maintained, they are still susceptible to error because lower quality electrodes respond to foreign ‘species’ (e.g. sodium). For this reason, if using an electronic pH meter, occasionally cross check your readings with a pH Test Kit.

Bluelab Combo Meter

It’s all you need for simple and reliable crop management.

The Bluelab Combo Meter is a portable pH, conductivity and temperature meter all in one. If you are experiencing problems with yellow leaves, or slow stunted growth, the Bluelab Combo Meter will soon tell you if each parameter is within the plants requirements. Adjustments can be quickly made to get your crop back on track.

The Bluelab Combo Meter has two probes, a Bluelab pH Probe and a Bluelab Conductivity/Temperature Probe. When taking a reading, simply place them into the solution and the selected reading is displayed on screen. As the Bluelab Combo Meter is portable and does not require a power supply to operate, it can be used anywhere, anytime to help you manage your crops’ daily nutrient requirements.

Calibration of the pH probe is simple as instructions are supplied on the back of the meter and the easy push button method makes this one of the simplest meters to use.

The pH probe is replaceable so you can use this meter for years to come. The Conductivity/temperature probe does not require calibration as this is locked in during manufacture.

Often referred to as “The Apple of Meters”!
