PRELIMINARY EXAMINATION

EC and TDS

are meters specially designed to

meet the needs of hydroponic and greenhouses.
The housing has been completely sealed against vapors and

humidity. They also float so that they can be quickly

retrieved if accidentally dropped in the tank.
The HI 1220 rugged EC/TDS probe incorporates a fast

responding temperature sensor. This means that readings

are quickly compensated for the temperature effect and they

are accurate every time. The probe can be simply replaced

and the rubber sleeve protects the DIN connector against

humidity and spills. The probe measures 25 cm (10”) and

can even be used to mix the fertilizer solution.

• Ideal for hydroponics and greenhouses

• Waterproof housing floats for quick retrieval

• Automatic calibration

• Auto switch off for longer battery life

• Fertilizer mixer (long and rugged probe)
