Grow Room : pH, TDS, PPM Testers and Controls
Whether using soil or hydroponics for your gardening, the proper
balance of your growing environment can be the life or death of your
plants. This area helps with the proper maintenance of:
pH: (chemistry) p(otential of) H(ydrogen) TDS: total dissolved solids PPM: parts per million EC: electrical connectivity
The Bluelab pH Truncheon has an auto-on and auto-off feature to preserve battery life. It uses 3-AA batteries. There area no external switches or adjustable buttons. Comes factory calibrated for instant use.
The EC Dipstick dissolved salts pen operates on 3 common inexpensive AA alkaline batteries.Measures in PPM, EC and CF scales. No calibration required. It calibrates itself each time you replace the batteries.
The Checker® supplies you with fast and accurate readings from 0 to 14 pH with a resolution of 0.01 pH. This compact tester features a large easy-to-read LCD and simple to perform 2-point calibration.
This durable tester offers replaceable pH electrode cartridge and cloth renewable junction. The Hanna Instruments Combo provides both adjustable ß and TDS ratio.
The casing of the popular DiST1 tester has been redesigned for increased strength, to better fit your hand and also offer a much larger LCD for easier viewing. The graphite sensors provide better repeatability since they do not oxidize.
The rugged pH electrode supplied with the meter is constructed using the latest double junction technology and a Hanna exclusive replenishable fiber junction.
A rugged all-round waterproof meter, the HI 9813 has a fast response probe to test pH from 0.0 to 14.0, EC from 0.0 to 4.00 mS/cm and TDS from 0 to 1999 ppm (mg/L).
Large LCD so measurements are easier to read from any angle. With the latest innovation of a nonclogging fiber junction the new pHep® meters last much longer.
It provides a battery level indicator with an automatic shut-off. Batteries last for about 250 hours of continuous use. The pH Electrode Cartridge is replaceable.
Hesi recomments a pH value is 6, but can range from 5.8 - 6.2, depending on your plants requirements and other growing conditions. If it falls much lower the roots can be damaged. If the pH value runs too high the plant cannot absorb all of the needed nutrients.
This floating, waterproof meter lets you choose between Fahrenheit and Celsius temperature readings, performs calibration and temperature compensation automatically, and has a replaceable probe.
When passing light trough a liquid the refracted angle will be shown on the scale determining the amount of dissolved solids in the liquid, letting you find how your plants are utilizing the nutrients.
The Milwaukee Sharp pH51 model provides a range of 0.0 - 14.0 pH with a resolution of 0.1 pH. It offers manual calibration of 2 points and is accurate at ± 0.1 pH. Environment 0 – 50°C / 100% RH.
It gives a range of 0 - 1999 ppm with a resolution of 10 ppm and is accurate at ± 2% full scale. This TDS tester gives you a manual calibration of 1 point and provides automatic temperature compensation of 0 - 50°C.
This waterproof EC / TDS / TEMP combination meter features an easy-to-read LCD screen, five-minute auto-off, data-hold functions and low-battery indicator. Expect battery life of about 100 hours of usage. The TDS Expert Plus meter even has Automatic Temperature Compensation (ATC) to ensure accurate readings.
