PRELIMINARY EXAMINATION
COMBO
is a combined pH/temperature/EC/TDS
meter specially designed to meet the needs of growers in
greenhouses and hydroponic applications.
You can simply install the meter above the sample to be
tested for continuous measurement.
The HI 1293D pH-electrode & the EC/TDS/Temperature
probe have been molded with pipe thread (1/2’’ NPT),
which allows the user to attach them to an in-line system.
Measurements are accurate and the meter can be calibrated
at one or two points for pH and at single point for EC/TDS.
You no longer need to worry about battery changes either:
the unit runs without interruption on 12 VDC power supply.

SPECIFICATIONS
Recommendations for Users
Before using this product, make sure that it is entirely suitable for the
environment in which it is used. Operation of this instrument in residen-
tial areas could cause unacceptable interferences to radio and TV equip-
ment.
The glass bulb at the end of the electrode is sensitive to electrostatic dis-
charges. Avoid touching this glass bulb at all times. During operation, ESD
wrist straps should be worn to avoid possible damage to the electrode by
electrostatic discharges.
Any variation introduced by the user to the supplied equipment may degrade
the instrument’s EMC performance.
To avoid electrical shock, do not use this instrument when voltages at the
measurement surface exceed 24 VAC or 60 VDC. To avoid damages or burns,
do not perform any measurement in microwave ovens.
