Hanna GroLine Waterproof EC/TDS Tester - HI98318

HI98318 is our latest pocket meter for measuring the EC/TDS of a hydroponic nutrient solution. This modern looking meter is only 0.7" thick and extremely ergonomic, fitting comfortably in your hand. The HI98318 has a very large easy to read LCD display that shows both EC or TDS and temperature along with calibration, stability and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on/off and the other for automatic one point calibration.

The GroLine Waterproof EC/TDS Tester is made specifically for hydroponics, provides a simple, inexpensive solution to measure fertilizer concentration in a nutrient solution.

The HI98318 EC/TDS tester has a graphite sensor that reduces the polarization effect common with amperometric testers that use two stainless steel pins.

Automatic calibration is achieved easily. Simply submerge the sensor in calibration solution and the meter will automatically detect the calibration standard (5.00 mS/cm in Quick Cal mode or 1.41 mS/cm in standard calibration mode). Temperature is automatically compensated for with the integrated temperature sensor.

250 hour battery life

Attention Valued Customer:

Ph testers and Ph probes are sensitive scientific equipment. They will require extra care and maintenance from the user (you) to ensure accurate readings, measurements and valid warranties.

Ph testers (without replaceable probes) and Ph probes are electrical sensors and considered a consumable item. You should aim to be replacing these over time as you do media, nutrients, etc. Probes and Pens (without replaceable probes) only have a 6-month warranty from date of purchase and will not be honoured without receipt of purchase.

Probes and Pens with proper care can last for years, but as it is a live charge in the electrode it can be finished from 6 months. More so, if correct care procedures have not been maintained. Hydroponic nutrients in particular degrade Ph probes much faster than other disciplines.

Probes must always be re-hydrated before use in storage solution, available for purchase in store

Probes must be kept in storage solution when not in use (in tank monitors excepted)

IF IT DRIES….IT DIES

Please read the entire contents of the booklets and handouts that come with all Ph instruments carefully.
