PRELIMINARY EXAMINATION

pH is a pH meter specially designed to meet

the needs of operators in hydroponics and greenhouses.

The housing has been completely sealed against vapors and

humidity. It also floats so that it can be quickly retrieved if

accidentally dropped in the tank.

The HI 1219 rugged pH electrode supplied with the meter, is

constructed using the latest double junction technology and

the HANNA instruments® exclusive replenishable fiber junc-

tion. The electrode can be easily replaced by the user, and

the rubber sleeve protects the connector against humidity and

spills.

Measurements are highly accurate and the meter can be

calibrated at one point.

• Ideal for hydroponics and greenhouses

• Waterproof housing floats for quick retrieval

• Manual one point calibration

• Renewable, pull-out junction

• Long battery life (up to 2000 hours)
