GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION
HI 993310 is an instrument that has been specifically designed for
rapid measurement of conductivity of liquids and soil. The meter is
supplied with two probes, HI 76305 with a stainless steel, conic tip
for direct soil measurement, and HI 76304 for fertilizer enriched
solutions.
The meter allows you to read two different scales with two LED lights,
on the front mask indicating which parameter is being tested. In
addition, HI 993310

HI 993310 is equipped with an alarm LED that
automatically comes on if the soil is too dry, or nutritive substances
are lacking.
Calibration for conductivity measurements can be performed with a
simple dial located on the front mask. It is not necessary to calibrate
the meter for salinity measurements.
Both probes incorporate a temperature sensor and the meter compen-
sates for the temperature automatically.

HI 993310 HI 993310 HI 993310 HI 993310 comes in a rugged splashproof case for outdoor
measurements and the 9V battery lasts 100 hours of continuous use.
Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any noticeable damage, notify your Dealer or the nearest
Hanna office immediately.
Each meter is supplied with:
• HI 76304 conductivity (plastic) probe
• HI 76305 soil (stainless steel) probe
• 9V battery
• Screwdriver
Note: Save all packing materials until you are sure that the
instrument functions correctly. Any damaged or defective item
must be returned in its original packing materials together

Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environ-
ment in which they are used.
Operation of these instruments in residential area could cause unacceptable interfer-
ence to radio and TV equipment, requiring the operator to take all necessary steps to
correct interferences.
The metal band at the end of the probe is sensitive to electrostatic discharges. Avoid
touching this metal band at all times.
During calibration of the instruments, ESD wrist straps should be worn to avoid possible
damage to the probe by electrostatic discharge.
Any variation introduced by the user to the supplied equipment may degrade the
instruments' EMC performance.
To avoid electrical shock, do not use these instruments when voltages at the measure-
ment surface exceed 24VAC or 60VDC.
Use plastic beakers to minimize any EMC interferences.
To avoid damage or burns, do not perform any measurement in microwave ovens.
