PRELIMINARY EXAMINATION

HI 981409

 and 

HI 981410 

TDS and EC meters have been

specially designed to address the needs of operators in
hydroponics, greenhouses and nurseries.
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 supplied 

HI 1220

 probe incorporates a fast responding

temperature sensor and is made with a rugged body ideal for
measurements in fertilizer mix. It  measures 24 cm (9.4”) and
can even be used to mix the solution!
The DIN connector is protected against humidity and spills by
a rubber sheath.
• Ideal for hydroponics and greenhouses
• Waterproof housing floats for quick retrieval
• Automatic calibration
• Auto shut-off for longer battery life
• Fertilizer mixer (long and rugged probe)
