PRELIMINARY EXAMINATION
The waterproof EC/TDS indicators
HI 993301
and
HI 993302
have been designed to meet the grower’s need for equipment
suited to the aggressive environments of agricultural and
hydroponics applications.
The instruments feature a large, dual-level, backlit LCD to
give instantaneous readings of both EC/TDS and temperature
even from a distance.
Calibration and temperature compensation are automatic,
while the TDS factor and temperature coefficient are user
adjustable for application specific measurements.
The
HI 7630
probe is provided with built-in temperature
sensor, and has been molded with pipe thread (1/2’’ NPT)for
an easy in-line installation.
Choose the indicator according to the proper EC/TDS ranges for
your application:
•
HI 993301
measures EC from 0 to 3999 µS/cm and TDS
from 0 to 2000 ppm
•
HI 993302
measures EC from 0.00 to 20.00 mS/cm and
TDS from 0.00 to 10.00 ppt
