Hanna Instruments, HI 981408: pH GRO'CHEK

• Ideal for hydroponics, greenhouses and nurseries
• Robust enough to mix the fertilizer solution itself!
• Waterproof housing floats for quick retrieval

HI 981408 pH Gro'Chek^® has been specifically designed to address the needs of the operators in hydroponics, greenhouses and nurseries. The meter has all the characteristics necessary to check the pH of the fertilizer mix during preparation. HI 981408 is sturdy and water proof. The HI 1219 rugged pH electrode supplied with the meter is constructed using the latest double junction technology and a Hanna exclusive replenishable fiber junction. In addition, the HI 1219 probe measures 25 cm and can be even used to mix the fertilizer solution! When the need arises to change the electrode, simply detach and replace it without taking it to a specialist. To resolve the problem of batteries going down and requiring frequent replacement, our R&D team has produced a meter that will run for 2000 hours continuously on the common AA-type batteries that come with it. This translates into more than 2 years of continuous service if the meter is used for up to 2 hours a day, every day of the week! Calibration has been simplified to one-point through a dial right on the front of the meter.

HI 981408 is supplied complete with HI 1219 pH electrode, pH 7 buffer solution, batteries and instructions.
