Digital pH/CF/EC Meters  

The Tri-meter


This meter measures ph level, nutrient levels in PPM or EC and nutrient temperature.

Measures ph, nutirent and temperature.
It comes supplied with a 2 year warranty

  Tri-meter £160.00
The Tri-meter combines the technology of the pH and Nutrient meters and addresses an additional key factor in Hydroponic growing, the temperature. The temperature in a growing solution is often over looked and can significantly restrict the growth and yield of the plants.



With no effort at all, reliable, continuous readings of Nutrient, pH and temperature can simultaneously be monitored and the correct levels maintained.

This is a continuous monitoring system that requires no batteries, just plug in and this meter will stay in a calibrated mode for months. The NutraDip Tri-Meter has automatic temperature compensation and is Three meters in one

2 year warranty supplied with a 3 ft (90 cm) lead on the probe featuring green LED for easy day or night viewing without disturbing the plant's photosynthesis 

Measures ph, nutirent and temperature.

Bluelab Dosetronic Peridoser


How does the Bluelab Dosetronic Controller work?

The Dosetronic provides continuous control of the desired levels of nutrient and temperature. All you do is program the required levels of conductivity, pH and temperature as the crop progresses through each growing phase. You retain control and the Dosetronic backs you up! This enables fast and accurate alterations to the feed system as the needs of the crop change.


  Bluelab Dosetronic Peridoser £1790.00

The Dosetronic can be used for a wide range of applications including Hydroponics, Horticulture, Agriculture, Floriculture and Aquaculture and is ideally suited for re-circulating hydroponic NFT systems.

Automated and accurate nutrient control

The Dosetronic provides continuous control of conductivity and pH levels of a solution by adding fertiliser and pH corrector into your mixing tank via peristaltic pumps or solenoids.

Bluelab Probe Care Kits

The instrument is only as accurate as the probe is clean!

Bluelab Probe Care Kits contain the essential tools and user instructions to help you maximize the life of pH or conductivity probes.

Probe cleaning is one of the most important parts of owning and operating any Bluelab meter, monitor or controller. If the probe is contaminated (dirty), it affects the accuracy of the reading displayed.

The probe surface is where the instrument takes the reading of the solution.
The information is sent back from the probe to the electronic brain of the instrument.
A calculation is then done in the instruments brain or micro computer and a reading is then displayed. If the information sent back from the probe is inaccurate due to probe surface contamination then the reading will be inaccurate. Cleaning the probes is a very easy task and prolongs the life of the probes.




The IWS Minute/Second Timer

The IWS minute/second timer is an easy to operate precision timer which can be switched from seconds to minutes. It has been designed with the grower in mind and gives you a greater degree of control over electronic products without the hassle of digital timers.

CO2 equipment, air and water pumps, dripper systems and fan control.

Plug & Grow 13 amp Timer

This heavy duty plug-in timer from Plug & Grow is a 24 hour, 15 minute segmental timer that is capable of switching high loads and it can control the on and off periods for one 600w HID light.

Plug & Grow timer

Most household plug timers cannot take the load required to strike a HID lamp and the contacts inside the timer will burn and weld themselves together, keeping your timer fixed in the on position and your grow light permanently running.
The 13 amp rating of this plug-in timer solves this problem and allows it to control your grow light without a lighting contactor being required.
